             Contract # CZI:92.03PD


             CONTRACTOR: American Littoral Society/Riverkeeper








            Background
            Riverkeeper, an affiliate of the American Littoral Society (ALS), has been
            working since 1988 to help protect and restore water quality and natural
            resources in the Delaware River Watershed. The watershed encompasses
            over 12,750 square miles from Delaware Bay to Hancock, NY.
            Riverkeeper volunteers monitor 87 stations in the watershed from the
            Bay to the headwaters near Hancock, New York. All but seven of the
            Riverkeeper stations are located on Delaware tributaries.

            This report reflects data collected at ten monitoring stations located on
            Delaware River tributaries in the estuary. These sites were established
            for Riverkeeper and the Pennsylvania Coastal Zone Management
            Program. In addition to the ten Riverkeeper / PACZM sites, 5 estuary sites
            in Pennsylvania have been monitored by Riverkeeper for the past two
            years. A copy of the Annual Estuary Data Report (May 1992-May 1993)
            which contains data from those sites will be be provided to PACZM
            January 1994.

            Three of the Riverkeeper/PACZM sites have become permanent additions
            to the Riverkeeper estuary monitoring program. They are Marcus Creek,
            Otter Creek, and Stony Creek. Monitoring at the remaining 7
            Riverkeeper/PACZM sites was terminated.

            PACZM Program Design
            Former Estuary Field Coordinator Tim Merkel began the site selection
            process and contact of potential volunteers monitors in November 1992.
            He left Riverkeeper early on in the study (January 1993) which created a
            delay in the volunteer training process. Fred Stine was hired as Estuary
            Field Coordinator in mid-January 1993 and saw the program through
            until monitoring for seven of the CZM sites ceased September 30, 1993.

            Seven of the Riverkeeper-PACZM sites were monitored by high school
            students under the direction of their science teachers. The monitoring
            program served both as a hands-on experience for the students in their
            respective. science classes and as a means of creating a sense of
            awareness and appreciation for their local streams. The remaining three
            sites were monitored by individuals who were recruited through press
            releases and public service anouncements.

            While the stream monitoring was conducted every two weeks, extreme
            weather conditions (freezing and heavy rains) conspired to reduce the
            frequency of testing during late winter and early spring. In addition
            continuity of testing for some of the sites monitored by high school
            students deteriorated during the summer when schools were out of
            session.









                      Results and Amalysis of Water Quality Parameters and
                                              Observations
                Results collected by the volunteer monitors for the Riverkeeper -
                PACZM program are presented here. Summary data for each station
                are presented in tabular form for each parameter, as well as
                observations and general comments.

                Volunteer Observations and Comments
                Volunteers were trained to observe wildlife, weather conditions and
                general water and habitat conditions. Overall, the observations
                reported by volunteers paint a portait of degraded streams, which is
                consistent with reports by volunteers from other Riverkeeper estuary
                sites located in the Philadelphia region. Typical water quality
                problems occuring in Pennsylvania's Delaware Estuary Coastal Zone
                include: trash/litter; combined sewer overflows, wastewater
                discharges; polluted runoff; and streambank erosion. While most of
                the coastal zone streams flow through urban or industrial landscapes,
                some creek watersheds, such as Neshaminy and Ridley are undergoing
                rapid development resulting in increased wastewater discharges,
                stormwater flows and sediment pollution.

                Most of the Riverkeeper/PACZM monitoring stations        reported
                problems with litter and garbage in and along the streams. Five of the
                sites reported serious sediment pollution. Heavy algal blooms were
                also observed at some of the sites. Oil sicks were reported at Tacony-
                Frankford, Darby and Chester Creeks; and a soapy discharge was
                reported at Marcus Hook Creek. Wildlife sightings were mostly
                limited to urban species such as pigeons, gulls and rats. However a
                Double-crested Cormorant was observed at the Schuylkill River site.
                Reports for those stations that reported significant observations are
                included with the monitoring data.

                Water Depth
                Water depth in the Delaware River Estuary tributaries is influenced by
                a number of factors. The river is tidal below Morrisville, and water
                depth in the tidal portion of the river and its tributaries exhibits large
                fluctuations during the tidal cycle. In addition, seasonal variations in
                runoff and rainfall also affect water depth. Water depth is normally at
                a maximum during the spring, when snow-melt from upstream areas
                and spring rains make significant contributions. Storm events can
                have localized, short-term effects on water depth.

                No specific trends or relationships between water depth and the other
                parameters measure were noted. The very dry conditions throughout
                the region during the late spring and summer of 1993 resulted in
                lower than normal levels for most area streams and the minimum
                depth at most stations was recorded during that period.








                Several. stations exhibited wide variations in water depth. The widest
                variation occurred at Schuylkill River where the minimum water depth
                recorded was .7 meters and the maximum depth was 13.2 meters. Other
                stations with differences between maximum and minimum depths
                exceeding 2 meters included Chester Creek, Darby Creek, Marcus Hook
                Creek, and Stony Creek.

                Transparency
                The transparency, or clarity of water is most often reported as the Secchl
                depth. This measurement is taken by lowering a circular white or black-
                and-white disk, 20 cm (8 inches) in diameter, into the water until it is no
                longer visible. Secchi disc transparency, or Secchi depth, corresponds to
                the depth where light intensity is 10 percent or less of surface levels, and
                approximates the lower limit of ma or photosynthetic activity. Through
                Its effect on the photosynthesis process, light intensity helps determine
                the species of plants and other aquatic organisms that can survive.
                Although somewhat simplistic and subjective, Secchi depth probably best
                represents the conditions which are most readily visible for recreational
                uses.


                Transparency is related to the transmission of light in water, and
                depends on both the absorption and scattering of light. The absorption
                of light in dark-colored waters reduces light transmission. Light
                scattering is usually a more important factor than absorption in
                determining transparency. Scattering can be caused by color, by
                particulate organic matter, including algal cells, and by inorganic
                materials, such as suspended clay particles in water. Suspended
                particulates are often the factor determining transparency in rivers.

                Most transparency readings were between . I and 1.0 meters, but no
                apparent trends were noted and the periods of both minimum and
                maximum transparency occurred at different times for different stations.
                Ridley Creek had the highest overall transparency with a mean of 2.7
                meters for the sampling period. The maximum transparency recorded
                was 3.8 meters at Neshaminy Creek, where the mean transparency was
                1.3 meters. The station with the lowest mean transparency was Stony
                Creek with a mean of 0. 5 meters and a low value of 0. 1 meters.

                Temperature
                Temperature affects a number of physical, chemical, and biological
                processes in natural waters. The temperature regime of a river is
                primarily a function of ambient air temperatures. Valile temperature is
                controlled primarily by climatic conditions, human activities such as
                wastewater and/or thermal discharges, can also have an influence. One
                of the most biologically-impottant temperature effects is the decrease in
                oxygen solubility with increasing temperature.








                Temperature results for the monitoring period followed expected seasonal
                trends. Maximum temperatures for all stations were between 20.0 and
                28.1 C and minimum temperatures were between 0.0 and 4.0 C at all
                stations (Note: these results do not include Ridley Creek and Chester
                Creek because of sparse data).
                Many stations were sampled less frequently during the winter months,
                which tended to skew the annual means toward higher values. The mean
                temperatures for stations reporting data on most dates appeared to be in
                the range of 13 to 20 C.

                pH
                The hydrogen ion activity in water provides an indication of the balance
                between acids and bases in solution. Hydrogen ion activity in water is
                usually reported as its negative logarithm, or pH. The pH of natural
                waters is an important general water quality indicator because pH is a
                major factor affecting most chemical and biological reactions. Accepted
                water quality criteria indicate a pH of less than 6.5 units may be harmful
                to many species of fish. The pH observed in water is determined by a
                number of complex interactions and provides an overall measure of the
                intensity of the various acid/ base interactions which are occurring.

                The pH scale ranges from 1 to 14 standard units. A pH of 7 indicates
                neutral conditions, while waters with a pH less than 7 are acidic and
                those with pH values greater than 7 are basic. Since pH is expressed on
                a logarithmic scale, each I unit change in pH represents ten-fold
                increase or decrease in hydrogen Ion concentration. Therefore, a pH of 6
                would be 10 times more acidic than a pH of 7 and 100 times more acidic
                than a pH of 8. The pH of normal rainwater (containing no pollutants)
                is about 5.6. As the rainwater travels over and through rocks and soil,
                chemical reactions with minerals affect the pH and buffering capacity of
                the water.


                The observed pH for most stations was usually between 6 and 8, but both
                high and low values were observed. Both the lowest and highest pH
                observed were readings of 6.0 pH units and 8.5 units at Darby Creek.
                The lowest mean pH was 6.5 for Stony Creek and Otter creek. Exact
                reasons for these low readings are uncertain.

                Readings at or above pH 8 were recorded at four stations. High readings
                are often associated with algal blooms because algae remove carbon
                dioxide, a weak acid, from water as part of the photosynthesis process.

                Dissolved Oxygen
                The dissolved oxygen (DO) concentration of a river is an important
                indicator of the overall "health" of the system. A great amount of
                information can be obtained solely through the analysis of this








                parameter. Dissolved oxygen concentrations are related to the
                photosyn'thetic activity of algae and weeds and., therefore, provide
                insight into productivity. Dissolved oxygen gradients provide an
                indication of mixing patterns and the effectiveness of mixing
                processes. Dissolved oxygen concentrations also have an important
                bearing on other physical and chemical properties, and on the
                composition of the biota in the river. For example, pollution sensitive
                species such as stoneflies (Plecoptera) and caddis flies (Tricoptera)
                require high oxygen levels, while other species such as midges
                (Diptera) can tolerate low dissolved oxygen levels. In general, species
                diversity increases with increasing dissolved oxygen concentration.

                The amount of oxygen which can dissolve in water is subject to
                fluctuations caused in part by variations in temperature,
                photosynthetic activity, and stream flow. Respiratory processes,
                oxidation of inorganic wastes, and the decomposition of organic
                matter deplete oxygen, while photosynthesis and re-aeration by
                contact with the atmosphere increase oxygen concentrations in water.
                Dissolved oxygen concentrations are of concern because oxygen is
                essential for the survival of fish and many other aquatic organisms.
                Most desirable aquatic organisms require a dissolved oxygen
                concentration of 4.0 ppm or greater for long-term survival.

                Dissolved oxygen concentrations were usually greater than 6 ppm at
                most stations; however, concentrations less than 5 ppm were
                observed at Stony Creek during August. Crum Creek, Marcus Hook
                Creek and Neshaminy Creek also recorded relatively low
                concentrations. Low flow conditions and high temperatures are a
                common cause of low oxygen readings during the summer months. It
                should be noted that all of these stations are in the Philadelphia
                metropolitan. area, where numerous wastewater discharges and CSO's
                have historically been responsible for low oxygen readings.

                High dissolved oxygen concentrations were observed at most stations
                in the winter months when the solubility of oxygen in water increases
                as a result of lower water temperatures. Several stations recorded
                dissolved oxygen concentrations of 13.0 ppm or higher.

                Dissolved Oxygen Saturation
                In addition to concentration, dissolved oxygen can be expressed in
                terms of percent saturation. The amount of oxygen that can dissolve
                in water decreases with increasing temperature and dissolved solids
                concentration. For this reason alone, dissolved oxygen concentrations
                in surface waters usually increase significantly during the winter'
                months. By eliminating the seasonal variations caused by temperature,
                dissolved oxygen saturation can provide a better comparison of
                dissolved oxygen in water between different sampling dates than
                dissolved oxygen concentrations.








                Dissolved oxygen saturation was closely related to dissolved oxygen
                concentration, but some differences were noted in station means.
                Sampling stations with an average dissolved oxygen saturation of less
                than 80 percent included Crum Creek and Stony Creek.

                Nitrate (N03-N)
                Nitrogen compounds are important nutrients for algae and aquatic
                macrophyte growth. The common inorganic forms of nitrogen in
                water are nitrate (No2) and ammonia (NH3), The form of inorganic
                nitrogen present depends largely on oxygen concentrations. Nitrate is
                the principal form of nitrogen in most surface waters, but high
                concentration of nitrate may reflect unsanitary conditions because
                human and animal wastes are major sources of nitrate. Nitrite is an
                intermediate form which in unstable in surface waters,. Ammonia is
                the nitrogen form stable under anaerobic conditions. Nitrate and
                nitrite are often analyzed together and reported as No3 + No2-n.,
                although nitrite concentrations are usually insignificant. 'Total
                KJeldahl nitrogen (TKN) concentrations include ammonia, organic
                nitrogen and particulate organic nitrogen. Nitrogen concentrations in
                algal cells are typically 10 to 20 times higher than phosphorous
                concentrations, and many natural waters have similar nitrogen to
                phosphorous ratios.


                Most reported nitrate concentrations were in the range of 0.8 to 3.0
                ppm. This concentration is typical of unpolluted surface waters. High
                nitrate concentrations (>4 ppm) were observed at 5 different stations
                at some point during the sampling period.

                Phosphate (P04)
                Phosphorous is an essential nutrient and is often the factor limiting
                additional growth of aquatic organisms. Total phosphorous represents
                the sum of all phosphorous forms, including dissolved and particulate
                organic phosphates from algae and other organisms, inorganic
                particulate phosphorous from soil particles and other solids,
                polyphosphates from detergents and dissolved orthophosphates.
                Soluble orthophosphate levels are more likely to be affected by algal
                consumption during the growing season.

                Some of the important external sources of phosphorous are fertilizers,
                septic leachate, sewage effluent, detergents and soaps, particulate
                materials transported by stormwater, and even phosphorus.

                Phosphate concentrations at most locations were generally less than
                1.0 ppm. Chester Creek had a mean phosphate concentration of 0.7
                ppm and was the only station wiih a mean phosphate concentration
                greater than 0.5 ppm.
