K13765.DO PREFACE To pursue the recommendations for further study that were prescribed in the Metropolitan Anchorage Urban Study, completed by the U.S. Corps o7 Engineers in 1979, the of Anchorage engaged CH2M HILL to conduct the Eagle River Water Resource Study. The purpose of the study is to investigate the potential sources of water supply from the Eagle River Valley. The original scope of the study comprised four tasks: Task I Well Drilling Program Task 2 Preliminary Damsite Investigation Task 3 Flour Water Treatment Study Task 4 Transmission Main Design Task 5, Eklutna Lake Alternative Water Source Evaluation, was added to the scope after the completion of the first four tasks. The report for each task is bound separately and is an appendix to the Executive Summary of the entire study. This Appendix III is the report for Task 3, Flour Water Treatment Study. ACKNOWLEDGMENTS We wish to express our appreciation to the Anchorage Water and Sewer Utilities staff for their contributions at the weekly meetings, updating of task scopes, and overall administrative assistance. Also, we thank Eklutna, Inc., for providing pertinent information at the weekly meetings and ready access to its property. v SUMMARY AND CONCLUSIONS The objectives of Task 3 are to (1 ) determine whether surface water from the Eagle River can be treated by conventional pro- cesses to remove glacial rock flour in order to meet current drinking water standards and (2) estimate costs for such treatment. Field and laboratory testing indicated that Eagle River water is treatable. Treatment facilities will require two different seasonal treatment processes that can be provided in a single water treat- ment plant. Transition between processes would occur in June and September correlating with melting of the glaciers at the river's headwaters. The recommended treatment processes are: (1) flocculation, sedi- mentation, high-rate filtration, and disinfection for the high-tur- bidity, glacial melt period; and (2) coagulation, high-rate filtra- tion, and disinfection for the low-turbidity period during the colder months. To provide flexibility and to meet increasing water demands, the treatment plant could be constructed in three equal increments of 23.33 mgd each until the full capacity of 70 mgd was reached. Additions could be made when needed with little disruption to continuing operation of existing facilities. Capital costs and annual operation and maintenance costs were estimated in January 1981 dollars for a 23.33-mgd and a 70-mgd plant. These estimated costs are $17.4 million (capital) and $1 million (operation and maintenance) for a 23.33-mgd plant and $41.4 million (capital) and $2.7 million (operation and maintenance) for a 70-mgd plant. Prior to starting final design but after selection of Eagle River surface water as the source for additional water supply, we recommend the following: � Pilot treatment plant tests for a full year, using at least a 1-mgd plant, to determine applicable process design criteria. This testing program should address iron, color, and turbidity removal; chemical dosages required over the full range of raw water parameters; filtration rates and media selection; and effectiveness of the recommended treatment processes. � Investigation of disinfection alternatives to identify their trihalomethane formation potential (formation of poten- tially carcinogenic substances during the disinfection process). vii 0 Identification of sludge disposal alternatives and the associated cost research. 0 Selection of a treatment plant site. 0 Groundwater quality analysis and monitoring program for the old Eagle River dump. viii on NO DEFINITION OF TERMS Alum Metallic salt, aluminum sulfate, coag- ulant used in removal of turbidity from water Coagulation A chemical process for combining particles into larger aggregates Degrees C Degrees centigrade 71 C = 450 F (Fahrenheit) and 200 C 680 F EPA United States Environmental Protection Agency Flocculation The process of gentle mixing following coagulation so that particles come in contact with one another, aggregating or growing into larger more dense particles that settle readily Flour Material ground by glaciers Jar Testing A bench-scale procedure using multiple stirrers to compare coagulation and settling results in beakers having varying coagulant dosages mgd million gallons per day mg/I milligrams per liter Micron Unit of measure equalling one thousandth of a millimeter NTU Nephelometric Turbidity Unit - unit for measuring turbidity Sedimentation Process by which coagulated or suspended matter separates from the water by subsidence and deposition THM Organic compounds formed when certain (trihalomethane) natural organic compounds (particularly humic acids) come in contact with chlorine.

Presently, surface water from Ship Creek and groundwater wells in the Anchorage Bowl supply most of the municipality's water. However, if pres- ent growth trends continue, these sources will not meet future needs. In 1974 the United States Congress authorized the U.S. Army Corps of Engineers to perform the Metropolitan Anchorage Urban Study (MAUS), which was completed in 1979. -TFe--purpose 7-T-e- 9-AUS was "to evaluate the adequacy of the developed water sup- ply in the metropolitan Anchorage area, to determine future water demands, to assess sources for water supply development, and to formulate water supply plans to meet the increased future demand" (U.S. Army Corps of Engineers, 1979). The MAUS study area comprised the Anchorage Bowl and the area northeast to the town of Eklutna (Figure 1-1). The projected future water demand increases, determined in the MAUS, are shown in Figure 1-2. It is expected that by the year 2025 an additional 81.5 million gallons per day (mgd) of water will be needed to meet the increased demands in the area. The MAUS report identified many potential sources of supply: Eagle River @Valley groundwater; Anchorage Bowl groundwater; and surface water from Campbell Creek, Ship Creek, Eagle River, and Eklutna Lake. Two plans were recommended by MAUS for future study. Plan IV, which ranked first environmentally and socially, included a combination of supply from Ship Creek, An- chorage Bowl groundwater, and Eklutna Lake. Plan VI, which ranked first on an economic basis, included an increased supply from Ship Creek, winter diversion from Eagle River, further de- velopment of Anchorage Bowl groundwater, and exploration for Eagle River Valley groundwater. To implement portions of these plans, the Municipality increased the water supply from within the Anchorage Bowl by recently con- structing a 36-inch supply main to its water treatment plant from the military diversion facility on Ship Creek. Future develop- ments are expected to include new wells to increase groundwater supply and the expansion of the capabilities of the plant that treats Ship Creek water. However, rapidly growing demands in Anchorage will require development of a new source outside the Anchorage Bowl within the next 10 years. The Eagle River- Chugiak-Eklutna area, northeast of Anchorage, needs a new source now. 1-1 /17 b "o 'o A4 CP 0 P ip KNIK Prv"R 'A GLENN 0 LI) 2 I H OD PETERS CREEK RI EKLUTNA LAKE CHUGIAK TOWN OF EAGLE RIVER RR -AMPGROUND BRIDGE ......

On the basis of the MAUS population projection, this diversion would satisfy the demands of the entire study area through the year 2012. The future increases in water supply capacity that are expected to be developed within the Anchorage Bowl will delay the need for the full 70-mgd capacity of the new water source outside the Bowl until approximately the year 2020 or later. The Eagle River Valley is one possible source of water from out- side the Anchorage Bowl that was suggested in the MAUS, Plan VI. To investigate the potential of this valley to supply the 70-mgd requirement, the Municipality engaged CH2M HILL to con- duct the Eagle River Water Resource Study. The original scope of the study comprised four separate tasks: � Task 1, a well drilling program to study the feasibility of developing the Eagle River Valley as a groundwater source � Task 2, a preliminary damsite investigation to determine the feasibility of developing the Eagle River as a sur- face water source � Task 3, an investigation of the suitability of conven- tional treatment processes for removal of glacial rock flour from the Eagle River water � Task 4, a preliminary design of a pipeline to transport groundwater or surface water from the Eagle River Valley to Anchorage Each task was conducted independently. The results of the first four tasks clearly indicate that a substan- tial dam and reservoir are required to develop Eagle River as a water source. Before committing itself to this dam and reservoir project, the Municipality of Anchorage increased the study scope to include Task 5, Eklutna Lake Alternative Water Source Evaluat- ion. The purpose of Task 5 was to analyze the capability of Eklutna Lake to supply the 70 mgd of water to the area. Eklutna Lake is included in Plan IV of the MAUS. The lake is 30 miles northeast of downtown Anchorage and 16 miles northeast of the Eagle River (Figure 1-1). The report for each task appears as an appendix to the Executive Summary of the enti.re study. This Appendix III is the report for Task 3, Flour Water Treatment Study. 1-4 PURPOSE AND SCOPE The objective of Task 3 is to investigate the suitability of the Eagle River as a potable water supply source, especially during the summer glacial melt period. It is intended to complement the MAUS and to augment water quality data collected by the United States Geological Survey (USGS) between 1948 and 1973. If the 70-mgd source of water for the Municipality of Anchorage is to come from Eagle River surface water (assuming it can be made potable), a plant to treat this water should be located near the river. This will allow potable water to be pumped south to the Anchorage Bowl and north to various communities as far away as Eklutna (Eagle River, Chugiak, Birchwood, Peters Creek, and Eklutna). Initially, when demands are still low, untreated water could be pumped to the existing Municipal Water Treatment Plant. However, it is likely that the Eagle River treatment plant would be constructed when the ' dam (Appendix 11 of this study) is constructed so the areas north can be served. To provide flexibility and to meet increasing demands, the treatment plant could be constructed in stages. This appendix contains the following: � Results and evaluations of field and laboratory tests � Identification of treatment criteria and the best treat- ment processes for both the summer glacial melt period and the winter clear water periods � Estimated project and annual operation and maintenance costs for a treatment plant suitable for operation of the recommended processes The Municipality of Anchorage suggested that we study flour con- centration, exchange capacity, particle size, mineral concentra- tion, solution characteristics, and treatment agents and methods. These suggested areas of the study, except for the exchange capacity and particle size, influence the treatment required to produce potable water and were considered throughout this task. Exchange capacity relates to ion exchange, which is a common process in water softening. Eagle River water is naturally soft and does not require softening. Particle size, though of interest, does not relate directly to its removal. Particle size distribution was measured but is not considered as having a direct bearing on either the jar tests performed or the treatment conclusions result- ing from these tests. Data were collected during the entire glacial melt period, June through September 1980. During this period, data were gathered regularly, and observations were made of variations in river water quality. 1-5 SITE DESCRIPTION The Eagle, River, situated about 10 miles northeast of Anchorage, is fed primarily by the Eagle Glacier at the upper end of the Eagle River Valley (Figure 1-1). During the summer, melt water from the glacier contributes to high flows. This melt water con- tains glacial rock flour, which produces high turbidity in the water. In the winter months when the glacier is frozen, stream- flow and turbidity are low. Its turbidity makes the Eagle River water unsuitable for drinking. A method for reduction of tur- bidity must be determined before the Eagle River can be identified as a potential drinking water source. LIMITATIONS This report was prepared for the use of the Anchorage Water and Sewer Utilities for specific application to the Eagle River Water Resource Study, Flour Water Treatment Study, in accordance with generally accepted engineering practice. No other warranty, ex- pressed or implied, is made. In the event of any changes to the conditions considered under this study, the conclusions and rec- ommendations contained in this report will not be considered valid unless the changes are reviewed and the conclusions or recommen- dations are modified or verified in writing by CH2M HILL. The purpose of this task is to investigate whether conventional treatment processes can remove glacial rock flour from Eagle River water. No design criteria were developed. The treatment con- cepts presented in this report are believed to be workable but are not refined enough for incorporation into a final design. Additional investigations, such as pilot testing, will be required prior to final design. 1-6 No Chapter 2 DATA COLLECTION AND EVALUATION SAMPLING SITE All samples for testing were collected from the right bank of the Eagle River immediately upstream of both the Glenn Highway bridge and the confluence of Meadow Creek with the Eagle River (Figure 1-1). This site was readily accessible during all weather conditions and permitted an undisturbed location to park the mobile laboratory. Because the river at this location is extremely turbulent; grab sampling from the river bank was considered as representative of the entire river. This was confirmed by taking samples upstream, near the center of the river, and measuring turbidity. Other sites further upstream were considered for regular sampling but were eliminated because they were less convenient and re- quired permits for access. No significant tributaries enter the river between the sampling site and either of the two prospective damsites, identified in Appendix 11 of this study. EQUIPMENT The mobile laboratory was equipped with a four-paddle stirrer, a Hach Model DREL turbidimeter, a pH meter, and miscellaneous other glassware and equipment for titrating. TESTS The testing started on June 11, 1980, and continued into Sep- tember, covering the entire rock flour, glacial melt period. Temperature, pH, hardness, alkalinity, and turbidity tests were performed at the sampling point. Also, jar testing was used to determine optimum coagulant dosage, effects of rapid and slow mixing, and floc settling rate. These tests were conducted daily until repeatable results to primary variables were established. Testing frequency was then reduced to 3 days per week unless significant changes in weather or stream condition occurred. In addition to on-site testing, samples were collected and trans- ported to an off-site laboratory for particle size analysis and other routine chemical and physical analyses. These tests were performed bimonthly throughout the testing period. Results of the on-site and off-site tests are shown on Table 2-1. Additional Eagle River raw water quality data, obtained between January and June 1981, is contained in Exhibit B at the end of this appendix. 2-1 Table 2-1 CHEMICAL AND PHYSICAL ANALYSES SUMMER 1980 Dates 7-23 7-28 8-8 B-15 8-25 8-29 9-5 9-19 Ca (mg/1) 12 11 12 13 19 19 21 12 Fe (mg / 1) 4.4 4.6 1.6 1.0 0.5 1.3 0.4 4.2 Mn (mg/1) 0.07 0.08 0.04 <0.05 <0.05 0.06 <0.05 0.07 Si (mg/1) 13.2 14.4 - - - - 2.8 10.4 M __F_ T8_ TO-.9 _@78 7@._l _777 - 22.3 U2 M9 11) Nitrate (mg/1) 0.26 <0.10 0.18 0.26 0.17 0.19 0.21 0.67 Sulfate (mg/1) 8.4 < 1 4.5 0.5 7.5 9.5 9.0 3.5 Total Dissolved Solids 137 79 99 71 92 110 105 85 (Mg / 1) Turbidity (NTU) 160 300 180 80 35 26 12 - 56 suspencled oriTs- M TOT Tff @T W TF -T.T T6 -I (Mg1l) Hd CACO 3 (Mg / 1) 44 - 43 55 64 70 78 52 Alkalinity as CaC03 Bicarb.

While air temperatures were gen- erally in the 15-degree- to 20-degree-C range, water tempera- tures held fairly constant at 6 degrees to 7 degrees C. During the test period there was a general relationship between air and water temperature. This is illustrated by the drop in both air and water temperature between August 29 and Septem- ber 8. Turbidity Turbidity ranged from 30 to 400 NTU, with the normal at about 150 NTU (Figure 2-2).

The river appears greyish in color, which is typical of the rock flour solids that create the turbidity. Periodically, samples were analyzed for both dissolved and sus- pended solids. Occurrence of these solids was plotted against turbidity (Figure 2-3). This plot indicates a rough correlation between turbidity and suspended solids, a turbidity of 75 NTU equaling approximately 100 mg/l of suspended solids. Dissolved solids remain more or less constant regardless of turbidity or suspended solids. Suspended solids particles that cause turbidity were analyzed for size distribution. The six samples analyzed showed that 90 per- cent of the particles were smaller than 2 microns, and 87 percent were larger than 0.5 micron. The particle count mean averaged 0.86 micron. The data from tests taken during the summer of 1980 closely re- semble water quality data gathered by the USGS during the period 1948 to 1973. (The USGS data are included as Exhibit A at the end of this report.) Suspended solids measurements and turbidity generally agree with historic data; however, the pre- vious high suspended solids loadings of 1,200 to 1,400 mg/l were not observed. Our maximum observation was 400 mg/l. Either the high loadings did not occur this year or they were missed, even though a conscious effort was made throughout the summer to take samples when changes in temperature, runoff, and rainfall were observed. pH The pH of Eagle River water was fairly constant, generally be- tween 7.3 and 7.5. This information is plotted in Figure 2-4. Alkalinity and Hardness Alkalinity and hardness vary seasonally and seem to correlate with turbidity. Both alkalinity and hardness decrease during the summer months, which are associated with higher streamflow and turbidity. Alkalinity varies from 50 to 60 mg/l in the winter to 30 to 45 mg/l in the summer. Similarly, hardness varies from 70 to 80 mg/l during the winter to 40 to 50 mg/l in the summer. Both the alkalinity and hardness of the Eagle River water during the sampling period are expressed in milligrams per liter as CaCO 3 in Figure 2-5. Jar Testing Jar testing is a bench-scale test that gives insight into full-scale coagulation and settling processes.

The effects of chang- ing water temperatures, rapid and slow mixing rates, and rapid and slow mixing durations were then investigated to refine the treatment requirements of the Eagle River water. Initial jar testing showed that two separate alum dosage ra nges achieved coagulation and clarification within a broad range of alum dosage. Figure 2-6 shows alum dosage plotted against turbidity after mixing and settling. The plot shows four distinct zones that occur frequently in treating highly turbid river water. When proceeding from left to right the zones can be described as follows: (1) insufficient alum, thus no coagulation, (2) effective alum dosage that achieves coagulation-clarification through desta- bilization of turbidity particles, (3) another zone of ineffective coagulation, and (4) a second zone of effective coagulation- clarification, this time resulting by adsorption and enmeshment of turbidity particles.

Figure 2-6 Coagulation of Water With High Turbidity 2-9 Plant-scale operation would use zone 2 rather than Zone 4 because less alum is used and a reduced volume of sludge is produced.Subsequent testing focused on this tower dosage to establish how dosage requirements varied with changing river turibity and temperature. The optimum alum dosage for the summer's test program was between 10 and 15 mg/l.The jar testing results showed that turbidity can be removed effectively through use of coagulation,flocculation, and sedimentation. The settled water produced from these procedures has a turbidity of 10 NTU or less for raw river water temperatures between 3 degrees and 7 degrees C regardless of turbidity.Fig 2-7 shows a typical plot of alum dosage against turbidity after settling. Figure 2-7 Settled Water Turbidity vs Alum Dosage Once the optimum dosage of 10 to 15 mg/l of alum was esta- blished, testing then turned to identifying whether an increase in water temperature above the natural river temperature would have a significant effect on coagulation, flocculation, and sedimentation (Figures 2-8, 2-9, and 2-10). In general, settling occurred more rapidly as the water temperature increased; however, the end 2-10 turbidity was the same. There is a possibility that river water could be preheated as it enters the treatment plant by waste heat energy from a future fossil-fuel-fired electric power plant being considered. Additional testing established, in a general sense, the effect of varying either or both rapid mixing and slow mixing on floc for- mation and settling characteristics. Rapid mixing performed best with the stirrer set at 90 rpm for 3 to 5 minutes, and the slow mixing appeared to be most effective at 30 rpm for 12 to 15 min- utes. Using optimum rapid and slow mixing, the best observed settled water characteristics resulted after 20 to 25 minutes. No attempt was made to correlate the jar stirrer with plant-scale mixing equipment. Because the alum dosage requirement was so low, little subse- quent testing was done using polymers as a substitute coagulant or as a coagulant aid. Use of alum as a coagulant has a side effect of lowering the pH of the water, which often increases the corrosiveness of the water to piping systems and household plumbing. Because the decrease of the pH using 10 to 15 mg/l of alum was observed to be small (from 7.5 to 7.2), it may not be necessary to add lime to raise the pH after coagulation to reduce corrosion. Lime systems are typically a nuisance to both operate and maintain. Further in- vestigation of this matter should be conducted during pilot plant testing. 2-11 50 Turb. = 62 NTU Temperatures: T, - at start of test 40- T2 - at completion of test T 1 7.50C, T2 = 9.5qC T 10.50C, T = 12.50C 1 2 Z T 12.50C, T = 146C 1 2 T 150C, T L 1 2 160C 30 cc F- 411 cc Lu NJ 20 Lu F- LU Cn 10 Aft. 0 5 10 15 20 25 30 ALUM DOSAGE (mg 1) Figure 2-8 Settled Water Turbidity vs Alum Dosage at Various Water Temperatures 150 RAW WATER TURBIDITY 400 NTU, T = 6.50C 300 NTU, T = 70C 240 NTU, T = 6.50C 170 NTU, T = 80C V 92 NTLI, T = 60C 20 NTU, T = 3.50C Alum Dosage 15 mg I 100 L z cc cc w Lu -j w 50- (n V: 0 T 0 5 10 15 20 25 30 35 40 45 SETTLING TIME (Min.)

Table 3-1 lists several of the more common water quality param- eters and shows both EPA Maximum Contaminant Level (MCL) requirements and natural levels of these parameters in the Eagle River. The Eagle River water exceeds MCL requirements in only turbidity, color, iron, and manganese.

The results of these analyses (conducted from January to June 1981) are documented in Exhibit B of this report. These results also indicate an excess of color in Eagle River water. During the eight coldest months when glacial melt ceases, the river is cold (zero to 4 degrees C) with low turbidity (2 to 40 NTU). During the summer, streamflow swells considerably, reflecting glacial melting. In the summer, the river exhibits tem- peratures ranging from 6 to 8 degrees C and turbidities ranging from 50 to over 400 NTU. The high turbidity caused by glacial flour may seem to present a treatment problem, but highly turbid water actually is more readily treatable. It is cold, low-turbidity water that generally presents the greatest treatment problems. Experience with Ship Creek water at the Municipal Water Treat- ment Plant indicates that removal of color and turbidity during periods of low raw water turbidity requires special treatment be- yond the addition of 10 to 15 mg/I of alum. The same may be true of Eagle River water. To enhance the coagulation, sed ,i- mentation, and filtration processes for effective color and low turbidity removal, lime addition at the headworks or other treat- ment methods might be required. In general, Eagle River raw water should be an excellent source of potable water but, prior to final design, it is strongly recom- mended that a full 1-year pilot plant testing program, using at least a 1-mgd plant, be conducted to establish process design criteria. This testing program should address iron, color, and turbidity removal; chemical dosages required over the full range of raw water parameters; filtration rates and media selection; and effectiveness of the recommended treatment processes. TREATMENT PROCESSES To satisfy the water treatment requirements most efficiently, the plant will require different operational modes to accommodate summer and winter variations. Figure 3-1 illustrates three pos- sible operational modes: conventional treatment, direct filtration, and in-line filtration. Conventional treatment uses flash-mixing of coagulants, flocculation, sedimentation, and filtration processes. This mode would be applicable during the summer months when the river turbidity is high--over 50 NTU. Direct filtration uses most of the above processes but would bypass the sedimentation basins. In-line filtration would bypass the flocculation and sedimentation basins but would move the coagulant application point closer to the filters.

The feasibility of using direct and in-line filtration should be confirmed by the pilot testing program. Conventional treatment is compatible with either the direct or in-line process. The transition, seasonally, from one process to the other would be easy. Bypass channels or piping is all that is needed to achieve operational flexibility. As might be expected, operational cost for either direct or in-line filtration will be substantially lower than for conventional treatment because of lower chemical dosages, reduced sludge production, and less equipment maintenance. TREATMENT PLANT Figure 3-2 shows a typical filtration plant flow schematic, and Figure 3-3 shows a preliminary layout for a 70-million-gallon-a-day plant. The plant could be constructed in increments with basins and filters added when needed with little disruption to continuing operation of existing facilities. From the layout, it can be seen that a 7-acre site will be required. Although plant site selection is beyond the scope of this task, desirable sites would be those that provide easy access during all weather conditions, minimize pumping requirements through careful site selection at the proper elevation, and eliminate the need for either raw or finished water pumping. Elimination of raw water pumping is more desirable, providing construction cost savings and reduced equipment wear. Finished water pumping can facilitate customer service along the transmission pipeline. Headworks The headworks contains facilities for application and mixing of chemicals plus a metering device to measure raw water flow into the plant. Chemicals can be mixed by using either an "in-channel rapid mixer" or a metering device such as a Parshall flume. Flocculation Floc nuclei (aluminum hydroxide) resulting from coagulation join together through numerous contacts and envelop suspended particles in the process. Upon sufficient mixing, the floc grows to a size and density that settle readily. It is important in both the flash-mixing and flocculation zones that equipment be furnished with variable-speed drives to allow variation in energy inputs. Because optimum mixing requirements vary from season to season, chemicals may be wasted if proper adjustments cannot be made. 3-4 HEADWORKS FLOCCULATION /SEDIMENTATION FILTER CLEARWELL BASIN BYPASS PUMP STATION . . . .

Because of the heavy rock flour load, the sed- imentation basins should be equipped with mechanical sludge re- moval equipment. It is anticipated that between 50 and 150 tons of dry solids sludge will be produced daily during the summer. Filtration System The settled water from the sedimentation area, containing a small amount of unsettled floc, proceeds to the filters. The filters re- move the remaining floc. Granular media filters consist of either two or three layers, each exhibiting a different size and specific gravity. The largest grain -media having the lowest specific gravity is located at the top of the filter with progressively smaller and heavier sizes toward the bottom. This arrangement permits floc and sediment particles to be removed throughout the entire filter rather than mostly at the surface as typically occurs in sing le-gra in-media filters. The addition of polymer as a filter aid immediately ahead of filtration improves floc removal within a filter, even at higher filtration rates. A nominal filtration rate of 6 gallons per minute per square foot is suggested for an Eagle River filtration plant. Pilot filter testing is needed to (1) verify the design filter rates, both summer and winter; (2) select filter- ing media specifically for local conditions; and (3) identify which chemicals are needed to aid filtration and in what quantity. Wastewater Disposal Sludge containing rock flour and sediment from the river is pro- duced in two locations in the plant: the sedimentation basin un- derflow and the filter backwash water. At a plant flow rate of 70 mgd and a raw water turbidity of 150 NTU, the quantity of sludge produced would equal 55 tons per day of dry solids, which would equal approximately 730 cubic feet per day of solids. Re- moval of solids. from sludge for ultimate disposal is often the most 'complex problem to be solved in the design of a water treatment plant. Generally, there are two means for clewatering sludge solids, either by natural means such as evaporation, percolation, and freezing or by mechanical means using such devices as vaccum filters, filter presses, and centrifuges. The cost for mechanical dewatering is usually three to ten times the cost for natural drying. Natural drying in drying beds or lagoons is the practical choice where climatic conditions permit drying to the degree that the sludge exhibits the characteristics of a solid that can be readily loaded for landfill disposal. Usually two or more beds or lagoons are provided to permit use of one while the other is drying. 3-7 More thorough evaluation of the local climatic and geologic condi- tions is required before a decision can be made regarding sludge disposal. Disinfection With the addition of disinfection, the water leaving the filters is of potable quality and ready for transmission and distribution to the public. Although chlorine has been the universal disinfectant in public water works, further consideration should be given to the use of other disinfectants for preliminary disinfecting while continued use of chlorine or hypochlorite will likely remain the choice for post disinfection as the water enters the transmission and distribution systems. Further investigation is required prior to selecting disinfectants and their application points within the plant. Trihalomethane formation potential needs to be determined upon selection of Eagle River surface water as supply source. ALTERNATIVE TREATMENT METHODS Alternative treatment methods were considered, some of which were reported by others in previous studies. These methods in- clude hydroclone separators, screening with microstrainers, and precoat filters. Only precoat filtration is applicable for the Eagle River conditions and could be considered an alternative to gran- ular media filtration. Historically, granular media filtration is the choice for public water supplies, especially installations over 5 mgd. The disadvantage of precoat filtration is the possibility of loss of the precoat from the filtering septum, allowing raw water to short circuit through the filter. Loss of precoat can be caused by hydraulic surges, changing flow rate, power failure, and operator error. Granular media filters are subject to operator error only. Further consideration of the precoat filtration is not considered worthwhile. 3-8 00 Chapter 4 COST ESTIMATE Table 4-1 shows the total project costs for a 70-mgd plant as well as a 23.33-mgd plant, which provides for ultimate plant develop- ment in three equal increments.

The estimated construction costs and operation and maintenance costs are based on actual experience for plants constructed and operated in the Pacific Northwest and have been adjusted to reflect costs for Alaska. They are also based on the EPA Esti- mating Water Treatment Costs, Volumes 1 and 2, and on the MAUS, Volume 2. These estimates are considered as order of-magnitude estimates with a -30 to +50 percent reliability range. Construction costs reflect the use of reinforced concrete construc- tion with all basins and filters being enclosed. The estimates 4-1 include finished water pumping (without standby power) but exclude both raw water and finished water transmission piping and raw water pumping. Construction costs are in January 1981 dollars using an Engineering News Record Construction Cost Index of 347. Although land costs are not included in the estimates, the site requirements are 7 acres for the plant and 23 acres for the lagoons--a total of 30 acres. 4-2 NO Chapter 5 NO BIBLIOGRAPHY U.S. Army Corps of Engineers, Alaska District, in conjunction with the Municipality of Anchorage.

NUMqER OF MISSING DAYS OF RECORD EXCEEDED 20% OF YEAR a Exhibit B Additional Testing 00 Exhibit B 00 ADDITIONAL TESTING It was concluded from Task 1, Well Drilling Program, that no sig- nificant groundwater supply exists in the Eagle River Valley. Emphasis was then placed on the study of Eagle River surface water as a potential means to meet the growing water demands of the Municipality of Anchorage. To supplement the data presented in this report for Task 3, Flour Water Treatment Study, samples of water were taken from eight sites along the Eagle River between January and June 1981 and were tested for quality. This Exhibit contains the data from this supplemental testing. The water sampling sites are shown on Figure B-1. Site A, Eagle River 200 Feet Upstream of Glenn Highway, Right Bank, corres- ponds to the Task 3 testing site. Other sites were chosen at various points to identify potential contamination sources. Coliform tests were performed on samples from all the sites; how- ever samples from Sites C and E were not tested on a regular basis. The results of these tests are shown in Table B-1. Complete State of Alaska drinking water standard tests were per- formed on water from Sites A and D on a regular basis, and from Sites E and H less frequently. The results of these tests are summarized in Tables B-2 and B-3. I Analysis of the results of the additional testing indicates that the Eagle River surface water should be suitable for human consump- tion if the proper treatment is applied to it. If this water is selected as a future drinking water source, it is recommended that further, more detailed water quality tests be conducted. Additionally, there are indications that groundwater is moving from the vicinity of the old Eagle River dump to the river.
