               RqTRODUCTION


                      In recent years preservation and protection of Chesapeake Bay has been a focus of
               attention in Virginia. As a result of concern over these environmental issues, the
               Commonwealth of Virginia mandated local governments to implement legislation and
               regulations to control land use practices in their respective jurisdictions. These regulations are
               designed to protect water quality. A number of governmental agencies and other organizations
               routinely conduct water flow and water quality monitoring within the Commonwealth.
               However, none of these monitoring programs focuses on describing the efficacy of emerging
               land use regulations in protecting water quality.

                      In April 1993 CBLAD initiated a water quality monitoring program in the Polecat
               Creek drainage. The primary goal of the monitoring program is to describe the efficacy of
               emerging land use regulations and policies in protecting adjacent water quality during urban
               development activities. Of course, the land use regulations and policies being tested are those
               developed by the CBLAD and the county governments in response to the Chesapeake Bay
               Preservation Act. The Polecat Creek monitoring system will provide information about the
               background state of water quality and about trends in water quality responsive to local land use
               regulations. This will be accomplished by measuring baseline levels of chemical, physical,
               and biological parameters and statistically evaluating any changes as the drainage is developed.

                      The Polecat Creek watershed lies in the south central section of Caroline County,
               Virginia (Figure 1). The headwaters rise in the piedmont, flow through the fall zone, and
               converge with the Mattaponi River in the coastal plain. The drainage area is about 30,000
               acres and is located in the headwaters of the Mattaponi River which is one of the main
               tributaries to the York River. The predominant land cover in the watershed is forest, followed
               by open fields and pastureland. About two thirds of the watershed is designated as primary
               growth area in the Caroline County comprehensive plan. Significant urban development
               activity is expected in the area over the next ten years.

                      The project is divided into three components: a system of water quality monitoring
               networks that will provide quantitative information about chemical, physical, and biological
               parameters; a database of land use activities and land cover characteristics in the watershed
               with a method to monitor changes in each over the life span of the project; and a geographic
               information system (GIS) which will link water quality data and land use/land cover data to a
               digital geographic base map.

                      The system of water quality monitoring networks is comprised of two different types of
               station networks, "axle" stations, and "wheel" stations. The "axle" is a network of stations
               that comprise the "back bone" of the monitoring program, and it is data collected from these
               stations which will be used to perform statistical trend analyses. These are fixed stations (that
               means that the station location does not change) at which samples are taken using standard
               operating procedures describing collection techniques at specific time intervals, using specific
               collection, preservation, and analytical techniques. These methodologies will not change over
               the life of the project (with the possible exception of chemical analytical methodologies).

                        Trend ("axle") monitoring will occur in four networks of stations in the Polecat Creek
                drainage (Figure 2). These will include:

                1.      a network of five stations equipped with automatic sampling equipment which will
                        monitor chemical and physical parameters (among those constituents to be monitored
                        will be flow, a suite of nutrients, temp, pH, DO, fecal coliform and fecal streptococci
                        bacteria). Data from these stations will be used to identify long-term changes or trends
                        in water quality. Flow data are essential in identifying long term trends in water
                        quality data because they allow concentration data to be converted to loading data and
                        allow concentration data to be normalized for season. Routine trend monitoring water
                        samples will be collected every 28-35 days.

                2.      a network of ten bionionitoring sites, including two off-stream sites. Biomonitoring
                        efforts will include monitoring benthic macroinvertebrate community structure (EPA's
                        Rapid Bioassessment Protocol III) and fish community structure (Index of Biotic
                        Integrity - IBI). These monitoring efforts will in the short-term describe biological
                        community structures and in the long-term record any changes in the community
                        structures. Biomonitoring is integral to any water quality monitoring program, but is
                        particularly important to the Polecat Creek project since this project will assess the
                        effectiveness of best management practices and land use regulations in the watershed.
                        It has long been recognized that "assessing the integrated response of biological
                        communities to highly variable pollutant inputs offers a particularly useful approach for
                        monitoring nonpoint source impacts and the effectiveness of certain BmPs (USEPA
                        1989). " Data analysis will be performed using the EPA recommended metrics
                        analysis. Samples for RBP III and fish IBI will be collected quarterly and three times
                        per year, respectively.

                3.      an off-stream network of rainfall gages and a weather station. These will record
                        quality, quantity and intensity of rainfall. Water quality parameters will include
                        nutrients, pH, and sulfate. These data are required in an effective nonpoint source
                        monitoring program for two reasons. Rain water is a potential source of nutrients as
                        well as pH and temperature changes to surface water. Secondly, quantity and intensity
                        of rain fall will describe how much and in what time frame water moves through the
                        system.

                4.      a network of ground water monitoring stations. CBLAD is currently planning the
                        implementation of a ground water monitoring component to this project.

                        In the network design, "wheels" are networks of stations that are actually special
                studies or intensive stream surveys. Typically, a special study network is an intensive
                sampling effort with a limited time frame and a specific information purpose related to a
                particular water quality problem that needs further definition. The "wheels" of the Polecat
                Creek project will be used to determine the potential sources or reasons for the changes in
                water quality. Examples of some special study networks include: monitoring during highflow

               events; monitoring logging and/or construction activities; monitoring base flow and high flow
               events near potential agricultural, commercial, or industrial nonpoint sources; and monitoring
               septic system discharges through groundwater to nearby streams.

                      The development of a land use/land cover data base and a GIS are integral components
               of the Polecat Creek Project. These will allow the linkage of land use/land cover data, water
               quality data and geographic data. The GIS will also be used to develop a nonpoint source
               pollution model for the watershed (using soils, digital elevation model, stream network, land
               use, land cover, flood plain, USF&WS wetlands, and other available digital data sets).

               PROJECT DELIVERABLE


                      This project proposal was written to fund chemical analysis of water quality data
               collected in the trend monitoring network of the Polecat Creek project. Samples were taken
               from five surface water stations (Table 1) and one rain gage. Samples were analyzed for a
               suite of nutrients, temp, pH, DO, and fecal coliform bacteria (Table 2).

                      All data (1994 and 1995) from the five surface water stations and rain gage are in
               Appendix A. Quality assurance, operating procedures, and analytical methodologies are
               located in Appendix B, Appendix C, and Appendix D, respectively.

                      This checklist is adopted from Taylor (1987) for use by the Audit Committee to appraise the program of the field and
                      laboratory. Each item should be considered individually and the appropriate score entered in the box. Intermediate
                      values may be chosen.

                      An average score of 3.5 is acceptable, but not laudatory. A score of 2.5 or lower is considered to be unacceptable and
                      indicates that serious risk exists in filed and laboratory operations. Inter-mediate scores will require a review of the QA
                      program to identify and rectify major deficiencies.

                      Even in the case of an acceptable average score, a low score for any item (<3) should be considered for possible
                      corrective actions.

                   ANALYTICAL EQUIPMENT










                CA. General Operating Procedures for Technicon AutoAnalyzer H

                This analyzer is a dual channel system: one channel is dedicated to orthophosphorus analysis, the
                other to total phosphorus analysis.

                System Startup:

                I .    Tighten tubes across pump so that the end blocks are in the end position on each side; put
                       on the pump cover (paten).
                2.     Turn on the pump power switch; allow distilled water to run through the analyzer.
                3.     Turn on sample power.
                4.     Check and make sure the water flow is going through the correct channel. Hookup the
                       sample flow tube; pull through tube and waste tube in the correct channel. Check and
                       make sure the 660 n@ filter is in the correct channel. Turn the polarity switch in the
                       correct direction.
                5.     Place the correct reagents lines in the specific reagents (the lines are labeled for each
                       reagent).
                6.     Turn on recorder and set amplitude to 50%. Allow 15 minutes to warm up.
                7.     Turn on colorimeter light source; allow 15-20 minutes to warm up.
                8.     Empty all waste containers into the appropriate waste jugs and make sure there is plenty
                       of fresh wash and reagents available.
                9.     Plug in heating bath.

                System Calibration and Operation:

                The Auto Analyzer H is calibrated using prepared standards before each analysis run.
                Orthophosphorus and total phosphorus are analyzed on the Auto Analyzer H. The same
                maintenance is performed on the Auto Analyzer II as is performed on the CFA 200. Additional
                information can be found in the attached "Technician Autoanlzyer Troubleshooting Guide". All
                calibration and maintenance operations are recorded in the Technician AutoAnalyzer II
                calibration/maintenance log books when performed.

                1 .    Set-the node switch to normal position.
                2.     Adjust the baseline using the alignment adjust knobs on top of the colorimeter. Turn the
                       channel adjust clockwise to lower the baseline, counter clockwise to raise the baseline. If
                       a baseline cannot be obtained use the opposite channel Adjustment in the reverse manner.
                3.     Insert pen in recorder and adjust chart paper.
                4.     Load standards and samples in the samples (clockwise). Standards are analyzed form
                       highest to lowest value.
                5.     Start the sampler by hitting the power button.
                6.     Adjust the standard peak height so that the highest level standard is at least 70% full scale.

                8.     Turn on colorimeter and light source; allow 15-20 minutes for warm up.
                9.     Empty all waste containers and make sure plenty of wash and reagents are on hand.

                System Calibration and Operation:

                The CFA 200 auto analyzer is calibrated using prepared standards before each analysis run.
                Ammonia, nitrate, and total Kjeldahl nitrogen tests are run on the CFA 200. The following items
                should be inspected routinely during each run: tightness of fittings, cleanliness and integrity of
                tuning, and proper fit and operation of mechanical parts. The pump tubes should be changed
                monthly or whenever they show signs of wear. The lamp should be dusted with a lint free cloth
                every 3 months and connections should be tightened. If the lamp shows blackness, it should be
                replaced. Every week a 5N sodium hydroxide solution should e run through the analyzer for 3
                minutes followed by 15 minutes of deionized water. Next, a IN hydrochloric acid solution should
                be run through the analyzer for 7 minutes followed by 15 minutes of deionized water. Every
                other week, air should be pumped through the analyzer. All calibration and maintenance
                operations are recorded when performed in the CFA 200 Calibration/Maintenance Log Book.
                Additional information can be found in the "Operation and Service Manual for CFS 200".

               C.3.   Digestion Block - Technicon BD-40

               Calibration and Maintenance


               The digestion block should be calibrated once per quarter. Insert a digestion tube filled with 3 5
               mL of mineral oil and a high temperature thermometer into the block. Set the block for 380'C
               and allow it to reach the entered temperature (at least one hour). Read the temperature from the
               thermometer, it should be within ï¿½ 5% of the set temperature. If the temperature is outside of the
               5% range, the procedure should be repeated after the block has cooled. If the temperature is still
               outside of the 5% range on the second trial, the block cannot be used and the manufacturer should
               be contacted for repair. The holes in the digest block should be cleaned of foreign material every
               month. Addition information can be found in the "Operation Manual for the Technicon Block
               Digester". All maintenance operations are recorded in the Block maintenance log. On the week
               of May 22, 1989, every position in the digestion block was tested and found to be within ï¿½ 5% of
               each other.











               CA      Incubator - Precision


               Calibration and Maintenance


               The incubator temperature is checked twice per day while the incubator is in operation.
               Temperatures are recorded in the incubator maintenance log. If the incubator temperature
               deviates by more than 5% from the desired temperature, it is sent to Laboratory Services for
               service and repair. Any spills are cleaned up immediately; the incubator should be cleaned once
               per quarter, or as needed. The incubator is used in the biological (bacterial) testing of water; it is
               operated at 35.0'C at all times. The then-nometer was calibrated by measuring the boiling and
               freezing pints of water. It was found to be accurate.

               C.5. Oven - Fisher Isotemp 300 Series

               Calibration and Maintenance


               The oven motor blower is oiled once per month using household mechanical oil. The oven should
               be cleaned once per month. The oven temperature is checked once per day and recorded in the
               Oven Log Book. If the temperature deviates more than 5% for the desired set temperature , the
               oven must be returned for repair. The temperature range for this oven is 40'C tp 200'C. The
               range for the thermometer is -5'C to 230*C. The thermometer was calibrated by measuring the
               boiling and freezing points of water. It was found to be accurate.


               C.6. pH Meter - Fisher Accurnet Model 750 [Laboratory Unit]

               Calibration and Maintenance:


               The pH meter is calibrated daily using prepared purchased buffer solutions. The buffer solutions
               are stored capped at room temperature. Subaliquots are taken weekly to calibrate the pH meter
               (or as needed). The buffers are replaced before they reach their expiration date. The pH probe
               and meter are checked quarterly using EPA quality control standards. The meter is calibrated and
               the EPA standard is measured in the same manner as a normal water sample. The pH reading
               should fall within the 95% confidence interval provided by the EPA; if the reading falls outside of
               the confidence interval, the pH meter is recalibrated using new standard buffers. The EPA
               standard is measured again. If the reading is still not within the confidence interval, the probe is
               checked. Make sure the probe is filled with plenty of KCL/AgCl saturated solution and check to
               see if the ceramic wick is clean. Recalibrate the meter after corrections have been made to the
               probe and retest the EPA standards. If the reading is still out of bounds, replace the pH probe
               and try again. If this does not work, send the pH meter to the manufacturer for repair.

               The pH probe is stored in electrode storage solution when the meter is not in use. The pH meter
               should be cleaned every month. Additional information can be found in the attached "Fisher
               Accumet Model 750 Operating Manual".











               C.7. Water Bath - Precision


               Calibration and Maintenance


               The temperature of the water bath is checked twice per day when it is in operation. The
               temperature should not fluctuate by more than ï¿½ 2*C from the set temperature. If the
               temperature exceeds this, the experiment must be repeated to ensure accuracy. The bath is filled
               with distilled ionized water so that the water level is within two inches from the top. The water in
               the bath should be checked daily during the experiments. The bath is emptied and cleaned
               quarterly. If the bath fails to maintain the desired temperature [ï¿½ 2'C] it should be sent to
               Laboratory Services for repair. See Precision Water Bath Operating Procedures Manual for more
               information. The water bath is used in the biological (bacterial) testing of water; it is maintained
               at a constant temperature of 44.5'C. The thermometer is calibrated manually and found to be
               accurate.


               C.8. Conductivity Meter - Fisher

               Calibration and Maintenance


               The conductivity meter is calibrated electronically every quarter. The calibration is checked with
               and EPA Quality Control standard every quarter. If the results are outside of the 95% confidence
               interval, the meter is recalibrated and the standards are retested. If the results are still not
               acceptable the meter should be returned to the manufacturer for repair or a new conductivity
               probe should be used. The conductivity probe is rinsed well with deionized distilled water after
               each use. Additional information can be found in the "Fisher Digital Conductivity Meter
               Operating Manual". The EPA conductivity standards are also used to check the conductivity
               meter during daily operation, the readings should be within the 95% confidence interval. If the
               reading is outside the 95% interval, the conductivity meter is recalibrated.

               C.9. Automatic Diluter - Hamilton Micro Lab M


               Calibration and Maintenance


               The pipet in the diluter is washed with deionized-distilled water before and after each dilution is
               performed. The diluter is calibrated automatically each day the diluter is used. The calibration is
               checked by diluting standards and EPA control samples of known value. The samplers are tested
               for reproducibility and recovery within the limits of the tests. If the samples do not fall within the
               accepted limits for reproducibility (ï¿½ 3%) and recovery for all tests, the diluter is recalibrated and
               the samples are rediluted and retested. If the samples still do not meet the accepted requirements,
               the diluter must be sent to the manufacturer for repair. The diluter is cleaned once per moth. All
               calibration results and maintenance operations are recorded in the diluter maintenance notebook.
               Additional information can be found in the Harriilton Micro Lab M diluter manual.

               Calibration and Maintenance


               The laboratory refiigerators/walk-in cooler are maintained at 4'C _+ 2'C. To ensure this setting,
               the thermometer is monitored with a laboratory grade, liquid filled thermometer having and
               accuracy of ï¿½ I 'C or better and a resolution of I 'C or better and placed in each unit. Placement
               of the thermometer is in the approximate center of the samples/stocks within the reffigerator. The
               temperature is monitored and recorded (in refrigerator by log book) each day. Adjustments to the
               thermostat setting are made if required. If adjustments are made, more frequent monitoring is
               performed until the temperature has stabilized.

               CAL Balance -Fisher Scientific Series XA


               Calibration and Maintenance


               The balance should be calibrated once per day for every day that it is in operation. The balance
               should be kept free of dust and dirt; it should be cleaned once per week. Chemicals should never
               be weighed directly on the balance, they should be placed in an aluminum or plastic weight boat.
               Additional information can be found in the attached "Fisher Scientific Series XA Instruction
               Manual". All calibration and maintenance operations are recorded in the Fisher Scientific XA
               balance log book when it is perfon-ned. The balance is calibrated with an interval I OOg or a 50g
               NBS class S weight. The balance is checked with the 50g NBS weight. The balance range is
               0.0001 to 50g and 0.001 to 250g.

                     Purpose:       The purpose of this procedure is to ensure sample infcgtity,.Iccountability, and sample
                                    custody responsibility.


                                    1. Samples are retrieved at the sampling sitcs by the field observer; they are then
                                       assigned field numbers which are recorded on the log-in sheets. The bottle
                                       -numbers for the samples are also recorded oil the log-in sheets. Each sample will
                                       have an individual field number and bottle number. The retrieval dates, times,
                                       and methods are also recorded on the log-in sheets. After the samples are re-
                                       trieved and checked-in they are transported to the rcrrigerator located at the main
                                       site and stored at 4'C.
                                    2. The samples are retrieved and transported to Virginia Tech on a monthly basis.
                                       The samples are collected by the field technician and are checked off against the
                                       log-in sheets. Any missing samples or any sample problems are recorded in tile
                                       trip log kept by the field technician. After the samples have been checked off, the
                                       field technician records a field out date, his initials, and any comments on each
                                       log-in sheet. The samples ate then transported by truck to Virginia Tech and are
                                       stored in the walk-in cooler at 4'C upon arrival. Sample problems ate discussed
                                       with the project engineer and the lab managcr within 24 hours of sample arrival.
                                    3. Log-in sheets are separated by the lab manager by site; each sample is assigned a
                                       separate lab number, and all samples are assigned a group code. All nutrient
                                       water samples have letter prefixes before their lab numbers (i.e. Z1234). The
                                       samples are numbered by site in tile order of their Field numbers. Lab numbers
                                       for all samples are recorded on the log-in sheets. If there are more than 120
                                       samples, the samples are separated into two groups; each group code consists of
                                       two letters (i.e. AH).
                                    4. Samples are retrieved from the cooler and brought to the lab. The samples are
                                       separated by site and a lab number is recorded on the top and side of each sample.
                                       Samples are checked off on the log sheets as they are numbered. If there is more
                                       than one bottle for a sample (Feld number), a composite sample is required.
                                       (Precipitation is often shipped in mote than one bottle because of the large
                                       amount of sample collected for each rainfall event.) The number of bottles con-
                                       taining a sample is listed on the log-in shect; an equal portion of sample from
                                       each bottle is required for the composite sample. The volume of the composite
                                       sample never exceeds 500 ml,. I'Ach sample bottle is shaken vigorously and a
                                       portion of the sample is measured out using a graduated cylinder. The sample
                                       portion is then added to a clean sample container. This procedure is repeated for
                                       every sample bottle that has the same field number. The composite sample is
                                       then labeled with a lab number, field number, and site code.
                                    5. Any sample irregularities are recorded in the laboratory log-in noteb, onk. After
                                       all samples for each shipment have been logged in, tile log sheets are assigned a
                                       log-in date and initiated by the lab manager. Copies (if the original log sheets are
                                       made and passed on to the project engineer. At this time sample problems are
                                       discussed with the project engineer; all decisions (in sample status are made.
                                       Sample numbers and reasons for nonanalysis arc recorded in the lab log-in note-
                                       book. After the samples are analyzed, they are stored in the walk-in cooler at 4
                                       'C for six months. The samples are stored so that information recorded on bot-
                                       tles can be cross checked with lab, log-in, and electronic information.









                     Appendix D-2 Sample Preparation/Sample Storage

                     Scope:         This operating procedure will describe the methods for sample analysis and sample
                                    storage preparation.

                     Purpose:       The purpose of this procedure is to dcrinc the correct methods for sample preparation
                                    and storage so that all obtained results are as accurate and correct as possible.
                                    After all samples are brought into the lab and logged in, they are prepared for analysis
                                    and storage. Samples are filtered in the lab within 48 hours of receipt from the field.
                                    The samples are fdtcred for ammonia, nitrate, orthophosphorus, filtered TKN and
                                    filtered total phosphorus. The remaining sample is acidified with 112@S(), to lower the
                                    p1l below two, and it is stored at 4'C. The Filtered portion of the sample is not
                                    acidified due to interferences caused by acidification. The filtered portion of the
                                    sample, used for filtered TKN and filtered total phosphorus testing, is acidified to a
                                    pil below two and stored at 4'C.

                     Procedures:
                                    1 . Samples to be filtered are removed from the refrigerator. No more than thirty
                                        samples should be removed at one time.
                                    2.  Filtered sample storage containers (Dilutc-it vials) arc numbered for every sample
                                        that is removed from the refrigerator. A duplicate filtered sample is required, and
                                        duplicates are filtered for all samples whose lab numbers are multiples of ten.
                                        Spikes are also created and are Filtered ror all samples whose lab numbers are
                                        multiples of ten.
                                    3.  A cone folded filter paper is placed in the top or cach storage container (particle
                                        retention size of 2.5-1.6 microns, Whatmin Cjl-,-A; Getman type A/E,;
                                        Fisherbrand G6). One sample is shaken vigorously (at least twenty times) and
                                        poured into the filter on the appropriately numbered storage container. An in-
                                        dentation is made in each filter to allow proper flow of filtered sample into its
                                        storage container. A spatula is used to indent the filter, it is rinsed with
                                        distilled-deionized water between each sample. For every new package of filters
                                        that is used, a filter blank is created. Distilled-deionized water if filtered and the
                                        filtrate tested for nutrient contamination. If a filtered sample shows contam-
                                        ination from solid materials (cloudy appearance or particulate material in Filtered
                                        portion of the sample), the sample must be refiltered using a new filter and the
                                        previous filtrate discarded,
                                    4.  The filtered samples are transferred from the simple storage containers to
                                        autoanalyzer cups. Three cups are needed for each sample, dup6cate, and spike.
                                        The autoanalyzer cups are labeled with the appropriate lab numbers and the fil-
                                        tered samples are transferred so that no contamination between samples can oc-
                                        cur. The filtered samples stored in autoanalyzer cups are capped and kept a(
                                        4"C until they are analyzed.
                                    5.  The unfiltered samples are again shaken and filtered as in step 3; the same filter
                                        can be used. At least 20ml. of filtered sample is collected for each of the samples.
                                        The filtered samples are acidified with one drop (measured with a Pasteur pipet)
                                        of cone. 11,SO4. These -samples arc capped and stored at 4'C until they are ana-
                                        lyzed. The unfiltered samples arc acidified with -,even drops of cone. II,S04
                                        (sample volume of 450-850 ml,). These sample-, are stored at 4'C until they are
                                        analyzed.
                                    Ammonia, nitrate, and orthophosphorus arc analyzed within seven working days of
                                    sample Mtration. TKN and total phosphorus (Filtered and non-Filtered) arc analyzed
                                    within 28 days of sample receipt. All samples are stored in polypropylene containers.
                                    Samples stored in autoanalyzer cups are stored in containers made of polystyrene.
                                    All types of water samples used for nutrient analysis -ire treated in the same manner.

                      Appendix D-3 Procedures for the Determination of Total Suspended Solids

                      A well-mixed water sample is filtered through a weighed standard glass-fiber and the residue retained
                      on the filter is dried to a constant weight at 103-105'C. The increase in weight of the filter represents
                      the total suspended solids.

                                   3. Add 1.5-2.0 g catalyst to each tube with a spoon
                                   4. Add 3 mL of concentrated sulfuric acid to each tube with a calibrated auto-pipet.
                                   5. Heat in a digestion block overnite at 120'C to drive off 1120 -
                                   6. Raise the block temperature to 200*C for I hour.
                                   7. Cap each tube with a small funnel.
                                   8. Raise the block ter@perature to 3RO'C and digest samples for 3 hours.
                                   9. Turn off digestion block and allow sample,; to cool (2-3 hours). After thesamples
                                      have cooled transfer them from the block to the fume hood.
                                   10. Rinse the funnels with distilled water.
                                   11. Slowly add distilled water to the samples. Bring the volume in the tube up to
                                      approximately 35 mi. and let stand overnitc.
                                   12. Vortex mix the samples until the solids are dissolved. Add distilled water to each
                                      sample so that the volume of sample is exactly 50 ml-
                                   13. Cover and invert 20 times.

                       Appendix D-5 Procedures for the Determination of Orthophosphates

                       This method covers the determination of orthopliosphatcs in water. The range for this method is
                       0.01 to 1.0 mg P/L

                       Ammonia molybdate and antimony potassium tartrate react in an acid medium with dilute sol-
                       utions of phosphorus to form an antimony phospho-molybdatc complex. This complex is reduced
                       to an intensely blue colored dye by ascorbic acid. Orthophosphate is the only form of phosphorus
                       to form a blue dye in th,is method.

                       Interferences:
                                      1. High concentrations of iron can precipitate and cause a phosphorus loss.
                                      2. Turbidity must be removed from the sample before it can be analyZed.

                                   tration is greater than 1.5 mg1I., the sample can be diluted and rerun so that the
                                   mg/L value wil fall within the analytical range for this test.

                   Appendix D-10 Methods of Using Laboratory Notelmoks
                   There are several types of notebooks used in lab to store various types of information. Notebooks
                   are used to store raw data read from strip charts, data read directly from instruments, and infor-
                   mation regarding samples status and equipment maintenance. All notebook entries are made in ink.

                   personal notebooks are used to store results read from a strip chart. The tests that are recorded in
                   personal notebooks include Total kjeldahl nitrogen (filtered and nonfiltered), total phosphorus
                   (filtered and nonfiltered), ammonia, nitrates, and orthophosphorus. The first two pages of the
                   personal notebook are used as a table of contents. The table or contents includes the type Of tests
                   recorded in the notebook, the page number, and from which chart the data was read. Each page
                   of the lab notebook has 3 columns: the first for the lab number, the second for the peak height,
                   and the third for the calculated value of the data. The chart number and the data of reading are
                   recorded on each page of the personal notebook.

                   The p 1-1 -conductivity notebook is used to record test results directly rrom instrument readouts. The
                   results are tabulated using 3 columns: the first for the lab number, tile second for the pil reading,
                   and the third for the conductivity reading. The analysts initials and date are also recorded in the
                   notebook for every set of samples tested.

                   The COD notebook is used to store COD data. The first column is used for the lab number, the
                   second is used for the percent transmittance reading for the first duplicate, the third column is used
                   for the second dupficate reading, and the fourth column is used to record the calculated ppm value.
                   The analysts initials and date of testing are recorded for each set of testing.

                   The solids notebook is used to record the results of the calculated values for nonfilterable solids
                   tests. Five columns are used to record the solids data: the first column is used for the lab number,
                   the second is used to record the dry filter and pan weight, the third is used to record the dry filter,
                   pan, and sample weight, the fourth column is used to record the volume of sample filtered, and the
                   fifth column is used to record calculated grams/litcr data.

                   Notebooks used to store sample status and equipment maintenance information are recorded in
                   paragraph form. All entries are signed and dated by lab personnel.

                     Appendix D-11 Methods        for Laboratory Data Collection, Reporting, and Storage

                     The purpose of this procedure is to define methods for data collection, data reporting, and data
                     storage so that all reported data is correct and accurate. The procedure also provides investigators
                     and outside agencies with a method for data tracking and validation.
                     Water samples are analyzed for various chemical species, including: orthophosphorus, ammonia,
                     nitrate, total kjeldahl nitrogen, soluble total kjcldahl nitrogen, total phosphorus, soluble total
                     phosphorus, total suspended solids, chemical oxygen demand, pit, and conductivity. There are
                     various methods for recording and calculating the results from these tests. After the results have
                     been processed, they are entered on the main report rile and then transrcrred to the HAS SAM data
                     base. This procedure will describe individual methods for collecting and reporting the various forms
                     of data.

                     A large majority of data is collected on a strip chart recorder. The strip chart consists of a toll of
                     graph paper on which peaks corresponding to samples and standards are recorded. Data for
                     orthophosphorus, ammonia, nitrates, total kjedahl nitrogen, and total phosphorus tests are all re-
                     corded using strip charts. Every strip chart used in the lab is assigned a lab number that consists
                     of a lab number with a C prefix (i.e. C21). After the,chart has been assigned a lab number, data
                     can be recorded on it. When all the data has been collected from a sample run, the chart is removed
                     from the recorder. The data, test identification, chart lab number, and initials of the analysts are
                     recorded on the end of the chart paper. The strip chart roll is then placed in the 'To Be Read File'
                     kept by the lab manager. The chart is now ready to be read. The data from the chart is read,
                     calculated, and recorded in a lab notebook. The itrip charts are stored in the "Read File' by the
                     lab manager. 'Me charts are stored by lab number and are kept for a minimum of one year.

                     The CFA-PC data handling system is also used to collect data from orthophosphorus, ammonia,
                     nitrate, total kjcdahl nitrogen, and total phosphorus tests. (See CFA-11C operation manual.) A rile
                     is created for each set of samples that is going to be run on tile Scientific auto analyzer. Each file
                     is given a lab number that consists of the test abbreviation code and a rile number (i.e. TKN53).
                     After the file has been created, data generated by the analyzer for each sample and standard is re-
                     corded directly into a CFA-PC file. When the analysis is complete, tile raw data is calculated using
                     the CFA-PC system software. A report of the calculated data is created and stored by the lab
                     manager. The report includes the filename, data, analysts initials, and data for each sample and
                     standard. Tile results are transferred from the CFA-PC report to the main report file by laboratory
                     personnel and verified by the lab manager.

                     Data for chemical oxygen demand tests are recorded in the COD notebook. Raw data for the
                     samples and standards, the date of the tests, and the analysts initials ire recorded for each run. The
                     raw data is calculated and stored in the COD notebook. The calculated data is transferred to the
                     main report file by lab personnel and verified by the lab manager.

                     pit and Conductivity tests results are recorded in the pit notebook. The date of the tests, and the
                     initials of the analysts are recorded for each set of tests. The result,; of these tests are entered directly
                     into the I IAS SAM data base.

                     Data from the total suspended solids tests are recorded in the solids iiotebook. Three values are
                     requited for solid measurements: dry pan and Filter weight; tile dry pan, Filter and sample weight,
                     and the volume of filtered sample. The amount of solids for each sample is calculated and recorded
                     in the solids notebook. The calculated solid-, data is then transferred to tile main report file by
                     laboratory personnel and verified by the lab manager.

                     The main report file is used to store the results obtained from the various tests. The rile is used to
                     enter completed data on the HAS SAM system and is also used as a backup to the TIAS SAM
                     System. The main report rile consists of pages that contain simple identification information and
                     test results for each sample. The pages have areas to record the lab number, site code, group
                     number, field number, and test results for each sample. (See attached sample file page.) After all
                     the sample information and results have been entered for one group of samples; that information
                     is transferred to the HAS SAM system. Once the data has been transferred, it is verified for cor-
                     rectness by lab personnel. Verification is accomplished by having one person read the values from
                     the original lab books while another person compares the spoken values with those written in the


                                                                                                                               24









                  HAS SAM system riles. All incorrect entries and sample problems are recorded in the IIAS SAM

                  Appendix D-12 Distilled- Deion ized Water/Glas-sware Cleaning

                  Scope:       This operating procedure will discuss methods for the production of distilled-dcionized
                               water and the cleaning of glassware in the Water Quality I ab.

                  Purpose:     The purpose of this procedure is to ensure the proper quality of reagent grade water
                               is produced and that all glassware is cleaned in the correct fashion.

                  Procedure:   Tap water is distilled using an electric still (Corning MP3-A) and a stem still
                               (Barnstead A 1013). Distilled water is collected in two 100 gallon polypropylene
                               containers. The distilled water is then gravity fed through a mixed bed high-resistance
                               cartridge (Barnstead Ultrapure) into a ten gallon storage carboy. Dist i tied -deionized
                               water is tested every week for conductivity. The conductivity of the water is required
                               to be less than I micromho/cm. If the distilled-deionized water has conductivity
                               greater than I micromho/cm, the deirinization column is replaced and the water re-
                               tested.

                               Glassware is washed with tap water and a laboratory detergent (Versa-clean). The
                               glassware is then rinsed with tap water. Next (fie glassware is rinsed in an acid bath.
                               The acid bath is a 150@6 IICL solution; IICL is used to prevent nitrogen contam-
                               ination. The glassware is thoroughly rinsed with the acid solution so that all surfaces
                               are coated. The glassware is then rinsed with distilled -dcionized water and allowed to
                               air dry so that no dust can fall into the glassware. After the glassware is dry, all
                               openings are coveted with parafilm and the glassware is stored.

                   Appendix D- 13 Laboratory Quality Control Procedura; for Nittrient Data
                   This procedure discusses the use and theory of control charts. It also defines the methods used for
                   quality control in the different analysis performed by the laboratory. Definitions and calculations
                   ate also provided in this procedure.

                   Quality Control Charts:

                   Quality control charts are used to help determine if a set of data is accurate and precise. One ad-
                   .vantage of control charts is that sample sets that are incorrect (out or control) can quickly be de-
                   tected. Control charts can also visualize trends in sample analysis. Two types of control charts are
                   used; X -charts and R-chatts. X-charts are used to record statistical data for check standards and
                   spikes. R -charts are used to record statistical data for duplicate analysis.
                   R - charts use a calculated mean and the standard deviation to determine whether as set of samples
                   is out of bounds. For check standards, a mean value is calculated anti compared to the theoretical
                   value of the check standard. (Check standards are EPA quality control samples; the mean should
                   fall within the 95% intervals provided by the EPA). The standard deviations of the check standards
                   are then calculated; the 95% confidence interval for the standards is equal to Xbar:e.ffpml.965,
                   where X is the mean and S is the standard deviation. The upper and lower control limits are de-
                   termined by R ï¿½2.58S, this is equivalent to the 99% confidence interval. There is a 5% chance that
                   the calculated data point will fall outside the 95% interval but only = 0.3% chance that the data
                   will fall outside the UCL or the LCL (upper and lower control limits). Any check standard that
                   falls outside the control limits is suspect; the check standard and the set of samples that was ana-
                   lyzed with it should be rerun. The values of the check standards should fall equally above and
                   below the mean value. There is only a 13% chance that 3 consecutive data points will fall on one
                   side of the mean. If more than 5 data points fall on one side of the mean, some action should be
                   taken to correct the analysis so that no samples will go out of control (prepare new reagents, cali-
                   brate instruments, etc.).
                   R -charts use the absolute value of the difference between two duplicate samples to determine
                   whether a set of samples is out of bounds. The mean value of the variance is calculated (R) and
                   plotted on" a graph; also lines ate plotted for 0.945 R, 2.456-Rthe 95% confidence limit, and 3.27
                   R the 99 % confidence fimit. 50% of the calculate variance should fall above the 0.845'ff line. Data
                   that falls outside the 99% confidence limit is suspect and the sample group should be reanalyzed.
                   The   -chart is interpreted like the X-chart.

                     Procedures:

                                   A. Quality control methods for ammonia, nitrate, orthophosphate, TKN, and total
                                   phosphorus tests.


                                   I -A series of standards are prepared for each set of tests. Standard curves are gen-
                                      erated from these standards and are checked for accuracy. The correlation of each
                                      curve must be greater than 0.99 and less than or equal to 1.0. If the correlation
                                      is not correct; standards that seem to be inaccurate are remade and the curve is
                                      regenerated.
                                   2. An EPA quafity control sample is run with each set of new standards. The con-
                                      centration of EPA sample is calculated using tile generated standard curve. The
                                      value of the EPA sample must all within the 95% confidence interval provided
                                      by the EPA. If the sample falls outside the interval, it should be rerun and recal-
                                      culated. If it is still not within the limits, a new set of standards is made and an-
                                      other EPA quality control sample is analyzed. The VPA sample is sent to another
                                      lab to verify its accuracy.
                                   3. Every month a X-quality control chart is prepared fn    Ir check standard results; an-
                                      other chart is prepared for spiked sample rcsults. ff-quality control charts are
                                      prepared monthly for duplicate result data.
                                   4. Results from check standards and spiked samples are compared to the previous
                                      months R-control charts. The data should fill within the 95% confidence inter-
                                      vals, if it does not, the sample set associated with the standard or spike should be
                                      rerun.
                                   5. Results from duplicate samples are compared to the previous months K -control
                                      chart. The data should fall within the 95% confidence interval, if it does not, the
                                      sample set associated with the duplicate should be rerun.

                                   B. Qua1ity control methods for Solids analysis

                                   L  A R-control chart is prepared monthly for duplicates run during solids testing.
                                      The duplicate results are compared to the previous months control chart and the
                                      results should fall within the 95% confidence interval. If the data does not fall
                                      within the expected range, the set of samples associated with the out of control
                                      duplicate must be rerun.
                                   2. An EPA quafity control sample is run for ever), 200 samples. The value of tile
                                      solids should fall within the provide(] 95"n confidence interval. If the value fall,-,
                                      outside the expected results, the procedure and Icclmician techniques should be
                                      reviewed.

                                   C. Quality control methods for COD analysis
                                   1. A standard curve is prepared for each sct of sampics that are analyzed; the corre-
                                      lations of the curve should he between OAR and 1.0. If the correlation is low, the
                                      standards that seem to be incorrect should dropped out.
                                   2. An R-control chart is prepared using ETA quality control standards; the control
                                      chart is prepared quarterly. The control standards ire compared with the X-corl-
                                      trol charts, the values should fail within the 95% confidence intervals. If the re-
                                      sults fall outside the confidence interval,-,, the sample set associated with the out
                                      of control standard are rerun.

                                   D. General quality control methods
                                   1. Performance evaluation samples are analyzed quarterly and the results are tabu-
                                      lated by an independent testing lab. The result-, arc tabulated by an independent
                                      lab. The results from these tests are used to determine the quality of tile lab re-
                                      sults.
                                   2. Bfind samples are run monthly for each test parameter; the results are compared
                                      to the control charts for each test. Blind sample.-, are used as a measure of the
                                      laboratory's quality.


                                                                                                                         29

                              1.  3 mL of a water sample to be used as a spike is removed from its autoanalyzer and
                                  transferred to a new auto analyzer cup. The sample is transferred in 3 aliquots
                                  using a calibrated I mL pipet.
                              2.  1 ml, of a mid to high range standard is added to the autoanalyzer cup that con-
                                  tains the 3 ml. of sample. The sample is capped ind shaken vigorously.
                              3.  The spike sample is run as a normal sample.

                   4.    Spike and Check Standard Calculations

                         Mean (X) = average standard value of check standards or avcrigc value of percent recovery
                         for spikes

                         95% confidence interval = X          1.965 where S is the standard deviation


                         99% confidence interval = X         IOS where S is the standard dcviation.

                         Percent recovery - the actual value obtained from an analyzed spike divided by the theoretical
                         value times 100;
                                                             actual     x 100 = % recovery

                       Theoretical value - the calculated value of a spiked sample.

                       i.e. One sample is run twice and an average of the results is taken. A spiked samples i prepared
                       by adding 1/4 of a known standard to 3/4 of the analyzed sample. A theoretical value can then
                       be obtained.

                       Average value = 3.0 ppm
                       Standard = 10.0 ppm 3.0 (.75) + 10.0 (.25) = 4.75 ppm theoretical value.

                  5.   Calculations for COD analysis

                       a.  convert % T to absorbance using A = log (1/I)

                           i.e. 93%T = log (110.93) = 0.032A
                       b.  plot the calculated absorbance values versus the concentrations of the measured standards.
                       c.  calculate the unknown sample concentrations using the standard curve.
