- The 75th Annual Water Quality Survey of the New York Harbor was performed ::lY the New York City Department of Environmental Protection during the 1984 summer season. Biochemical oxygen demand, Cl)liform bacteria (total and fecal), dissolved oxygen, - salinity, and temperatnre were meas11recl weekly in snrface ann bottom waters from firty-Lwu Blaliuns lur twelve Wf~ekH. Six nutrients, seven metals, twenty volatile organic compounds and plankton were also measured in samples from each station. Metal concentrations were measured in sedime:! 1 from most stations. A tidal cycle study and an investigation of coliform concentrations before and during seasonal disinfection were also performed this year. Coliform bacteria, BOD, and metals (except mercury) tended to increase this year over 1983 levels. Ten-year trends suggest favorable changes in lead, nutrient (orthophosphate and ammonia), and D.O. levels, but unfavorable changes in chromium levels for the harbor. Other parameters did not show any clear ten-year trends. Average D.O. levels were usually in compliance with NYS-DEC standards, but individual measurements show one or more violations at 81\ of the stations, especially in bottom waters. Bacterial concentrations exceeded the standards at about half of the stations. All metals, except chromium, exceeded DEC standards at some or all stations.

ii - INTRODUCTION
The ~5th Annual Water Quality Survey of the New York Harbor was performed by the New York City Department of Environmental Protectio:t' s Bureau of water Pollution Control between May 7, 1984 and October 15, 1984. The extensive historical database produced by this project shows trends in Harbor water quality, some dating back to 1909. The purpose of this report is to describe patterns of ambient water quality in the New York Harbor in 1984, and to present the latest Len-year trends. Ongoing computerization of historical harbor surveY. data will allow more complete presentations of trends in future reports.
Twelve new sampling stations located near tributaries in the New York Harbor were added to the forty stations sampled last year. The fifty-two stations were sampled at least twelve times each for dissolved oxygen (D.O.), biochemical oxygen demand (BOO), temperature, salinity, and total and fecal coliform bacteria in surface and bottom waters. Concentrations of - nitrogen (NH3, N03, and N02), phosphorus (total and dissolved orthophosphate), and total organic carbon (TOC) were measured in two samples collected on different days from each station. Metal - concentrations (Cd, Cr, Cu, Pb, Hg, Ni, and Zn) were measured once in sediment and water samples from each station. Twenty volatile organic compounds were measured in three top and bottom water samples from each station. Tidal cycle studies and a special pre-chlorination coliform study were also performed this year.
- METHODS
Harbor Survey personnel routinely sampled each of 52 - stations (Appendix A) once or more a week for salinity, temperature, dissolved oxygen, biochemical oxygen demand, total coliform concentrations in top and bottom water, and fecal coliforms in samples composited from top and bottom. Surface and bottom samples were collected on May 7 and 9 from the Jamaica Bay stations and were analyzed for total and fecal coliforms to provide background bacteriological data before the NYC WPCP disinfection season. Routine sampling trips, covering all fifty two stations each week, began on June 11 and ran through October 15.
A special tidal cycle study measured top and bottom dissolved oxygen, water temperatures, salinity, and total coliform concentrations for 12 hours (6 am to 6 pm) during an ebb - and flood tidal cycle at each of the three limits of the harbor: the Hudson River at Mount St. Vincent, the East River at Throgs Neck, and The Narrows in New York Bay. Samples were collected on each side of the waterway and in midstream every hour, except for coliforms which were sampled every other hour. As many samples as possible were collected to track thP ti~~l ~yrlP, ~imQ Lt:hilr·aluts on lllt:! ollli:Jlt:! ocuupllW:J Vt:!bbt:!l ana 1ucal conllltiom; determined the exact frequency of sampling and total number of samples collected. - - -1- - Water samples were collected while on board the R/V Harbor Survey, a steel-hulled 55 foot twin-engine diesel craft. Water - samples wel:e collected from top depthg (about two feet he 1ow the water surface) and bottom depths (about two feet above the sediment surface but no more than 40 feet below the water -- surface) •1sing Kemmerer "bomb" samplers. Dissolved oxygen samples were placed in BOD bottles without aeration and were analyzed immediately after collection using the azide modification of the Winkler m· thod. Temperature and salinity were measured on board immediately after collection using a combination mercury thermometer/temperature-corrected - specific gravity hydrometer assuming specific gravity of 1 .0250 at 60•F as 100 percent (33.7 ppt salinity) seawater.
The biochemical oxygen demand analysis required vigorous - shaking of approximately two liters of sample in a three liter polyethylene bottle followed by carefully filling two 300 mL BOD - bottles with the aerated sample. One of the bottles was - evaluated for initial DO using a YSI DO meter and the other BOD bottle was placed into a rack and held at ambient air temperature in darkness until the boat docked at mid-day. Thereafter, it was immediately transported by car to · the shore laboratory and incubated for five days at 2o•c followed by DO determination.
The multiple-tube fermentation technic for total coliform - bacteria was begun on board by aseptically inoculating five tubes of lauryl tryptose broth in three serial decimal dilution portions, for a total of 3 x 5 = 15 tubes per sample. The amount of sample water used depended on expected coliform concentrations for each stat ion. After docking at mid-day, the tubes were immediately transported to the shore laboratory for 35•c incubation. The presumptive test was followed by the confirmed - test using brilliant green bile media (Standard Methods 15th ed.). Data were reported as coliform MPN/100 ml.
The membrane filter technic was used to determine the fecal coliform concentrations in the harbor waters. Equal portions of top and bottom samples from each station were composited immediately after sampling and were then aseptically filtered - through a 0. 7 micron membrane with the aid of a hand vacuum pump. The amount of sample filtered depended on expected fecal coliform concentration. The membrane was aseptically removed from the filter holder and placed into a 50 mm Petri dish - containing M-FC (fecal coliform) media. After mid-day docking, the samples were transported to the shore laboratory and incubated at 44.5•c for 24 + 2 hours of incubation; the - appropriate colonies were then counted and reported as fecal coliforms/100 ml (Standard Methods 15th ed.).
The geometric mean is used in place of the median as an - estimate of central tendency of coliform concentrations. The geometric mean is used for comparison with standards, some of - which are based on median values.
- -2- - - concentrations of cadmium, chromium, copper, lead, mercury, nickel and zinc in harbor waters were determined by atomic absorption spectrophotometry. Equal volume composites. of th: t<:>P - and bottom samples from each station were placed 1nto v1rg1n polyethylene bottles containing concentrated nitric acid as a preservatjve. Mercury concentration was determined by the - standard flameless absorption technique on the acidified water sample. Because of interfering substances in seawater and the expected low levels of metals, an ion exchange resin column {Chelex 100) was used to adsorb the metals and remove the - interfering substances prior to ~he atomic absorption spectrophotometric analyses for cadmium, copper, nickel, lead and zinc. Chromium was detrermined on the raw seawater samples by the method of additions because Chelex 100 resin does not adsorb this metal. Metal concentrations in sediment were determined by atomic absorption spectrophotometry according to EPA region II - procedures (July 1977). Nutrient concentrations were measured in samples acidified with H2S04 to pH < 2 using a Technicon Auto Analyzer II according - to Methods for Chemical Analysis of Water and wastes (EPA-600/4-79-020r Revised March 1983).
Sediment metal analyses, except for mercury, were performed - on dry sediment after removal of all large organisms and shells and passage through a 9.5 mm mesh seive. Mercury analyses were performed on wet sediments subjected to the same removal and - sieving. Mercury concentrations for dry sediments were calculated from the solids percentage.
Purgeable, volatile, organic priority pollutants in surface - and bottom water samples were determined using us EPA, July 1982, test method 6 24. the Purge and Trap device was attached to a Hewlett-Packard Gas Chromatograph/Mass Spectrometer/Electronic - Data System and run in the very sensitive, quantitative, select ion mode. Except where indicated three samples collected on different days were analyzed for each station.
RESULTS - A total of 46 regular sampling cruises producing 559 data records, 3 cruises for tidal cycle studies producing 156 data records, and 2 cruises for the special pre-chlorination study - producing 12 data records were performed this year. Each data record contained station number; date; time; current direction; top and bottom measurements of salinity, temperature, D.O., BOD, and total coliforms; and top and bottom average concentration of -- f~cal coliforms. Addition'll c'l Coliform Bacteria Average concentrations of total coliform bacteria ranged from a low of 40 MPN/100 ml at Little Neck Bay (Ell) to a high of 145000 MPN/100 ml at Flushing Bay south (E15). Coliform concentrations exceeded 10,000 MPN/100 ml at all stations in the -3- central harbor {except N6 and N7) bounded on the north by N2, on the east by E7, on the south by NB, and on the west by K5. -- Twenty-three surface and fifteen bottom stations on average exceeded the NYS-DEC standard for coliform. Fecal coliforms were most concentrated in Gowanus Canal (4230/100 ml) and The Kills, station K1 through K4, (3210/100 ml). Long Island Sound, parts of Jamaica Bay, and stations off Coney Island {N9, N9A, N16, and J11) had acceptable low concentrations of fecal coli forms ( <200/100 ml). Average fecal coliform concentrations exceeded NYS-r" .... standards at three of our fifty two stations (K5A, J3, and G2). - Total coliform concentrations increased this year in all branches of the harbor except Long Isl~nd sou~d and the Upper E st River Col iforms increased drastlCally ln the Upper New a . · • in the Harlem River.

Further deta1ls are 1n Appendlx - c. Dissolved Oxygen Minimum average 1984 dissolved oxygen for the harbor was 2.4 mg/1 in surface waters at Gowanus Channel. Maxmium average D.O. was 7. 7 in surface waters at Orchard Light in Lower New York Bay. D.O. levels were least in the southern half of the East River, in Gowanus, and in Fresh Kills. High levels were recorded - in Jamaica Bay, Lower New York Bay, and Long Island sound. Compliance with NYS 1984 standards for D.o. (season averages) was observed at all stations except G2, E15, and E8 - (Fig. XX). Gowan us Channel ( G2) sur face waters had an average D.O. of 2.4 mg/1 which is only 60\ of the required 4 mg/1; G2 bottom waters contained 3.8 mg/1 or 95\ of the NYS standard concentration. Flushing Bay South (E 15) bottom waters contained -- 3. 7 mg/1 D.O., 93\ of the standard. Throgs Neck (E8) bottom waters contained 4.9 mg/1 D.O. or 98\ of the required 5.0 mg/1. - Absolute compliance, since the standards state that D.O. "Shall not be less than ( x) at any time", was determined for ten of the fifty-two stations located in or near the Lower New York Bay. All other stations had D .0. 1 evels in viol at ion of the standards one or more times (see page D-5 for details). - -4- Surface waters usually contained more D.O. than bottom waters, except at downstream locations in New York Bay and in the - Kills east of Staten Island. Well-oxygenated ocean water moving upstream t-elow oxygen-deficient fresh water flow is responsible for this effect. Oxygen stratification was minimal at most stations ~xcept in the Hudson River north of the Battery. Dissolved oxygen has generally increased over the past ten years, but showed slight decreases in all branches of the Harbor - this year, except in the Hudson and Lower East Rivers. Further details are in Appendix D. - METALS: Water Column Concentrations Cadmium concentrations ranged from 0.1 ug/1 in the Raritan River (KSA) to 7.5 at Newtown Creek (E2A). Long Island Sound, - the lower East River, and much of the upper East River had elevated cadmium levels. The Harlem River, Hudson River, and upper and lower New York Bay st~tions tended to have moderate to low cadmium concentrations. Kill Van Kull, Arthur Kill, and - western Raritan Bay stations had very low levels of cadmium. Jamaica Bay concentrations varied spatially, but tended to be moderately low. The 1983 New York State standard for cadmium was - exceeded at three of the fifty two stations (EB, 9, 10) and was exactly met at one station (E6). Cadmium concentrations increased in seven of the ten major harbor branches this year over last year: Kill Van Kull, Arthur Kill and Upper New York Bay - had lower concentrations. Chromium concentrations ranged from 17.0 ug/1 at Orchard - Light (K6) to 4.2 ug/1 at Spuyten Duyvil (N2) and were well below the NYS standards at all stations. Chromium concentrations increased in eight of the ten major harbor branches this year over last year: Arthur Kill and Long Island Sound had decreased concentrations. Compared historically, chromium concentrations were high in 1984. Copper concentrations ranged from 130 ug/1 in Long Island Sound (E10) to 41 ug/1 at Spuyten Duyvil (N2). Tributaries in the upper East River, lower New York Bay, Gowanus, seven of ten Jamaica Bay stations, and miscellaneous other stations had - veryhigh copper concentrations (>90 ug/1). New York State standards for copper were exceeded at all stat ions. Copper at - the Kills, lower East River and North Harlem River stations exceeded the standards by factors of three to four. Concentrations at all other stations exceeded the standards by factors of ten to thirty three. Copper concentrations increased - in eight of the ten major harbor branches this year over last year1 Upper New York Bay decreased; Kill van Kull was unchanged. Compared historically, copper concentrations were moderatley high - in 1984. · Lead concentrations ranged from 17 ug/1 at Gowanus Bay to 46 ug/1 ~HS, N9A, and E10. Concentrations were four to twelve - times the New York State standards. Lead concentrations - -5- - increased in nine of the ten major harbor branches this year over last year~ Upper New York Bay had decreased concentrations. Compared historically, lead concentrations were moderately low in 1984 continuing the decreases first noted in the mid -1970's. Mercu.u concentrations ranged from the detection 1 imi t of - 0. 10 ug/l at seven stations to 1. 10 ug/1 at Spuyten Duyv il. General spatial trends among branches are not readily apparent, except possibly that the western Long Island sound and portions - of the upper East River had slightly lower concentrations. Of the forty-one stat ions which had mere:., 1 standards, E7, 8, 10, 11, and J8 and 9 were within the New York State standards, while mercury concentrations at K5, N8, N3A, N3, E15, E9 and H2 were - equal to the standard. Twenty-six of forty-one stations exceeded the New York State standard by 0.5 to 5.5 times. Mercury concentrations decreased in eight of the ten major harbor - branches this year compared to last year; Harlem River had increased concentrations; Lower New York Bay was unchanged. Compared historically, mercury concentrations were moderatley low - in 1984. Nickel concentrations ranged from 4. 3 ug/1 in Long Island Sound (E9) to 660 ug/1 west of Wards Island (H5). Two stations, - E10 and J5, had exceptionally high values of 2800 and 1000 ug/1, respectively which are probably erroneous readings. The upper East River, numerous Jamaica Bay stations and occasional other stations had elevated nickel concentrations. Thirty-six of the - fifty valid measurements contained nickel concentations in excess of the New York State standards. Acceptable nickel concentrations were found primarily in Kill van Kull, Arthur - Kills, and the lower East River. Nickel concentrations increased in five of the ten major harbor branches this year over last year: Lower East River, Upper East River, Long Island Sound, Harlem River and Jamaica Bay. Compared historically, nickel - concentrations in 1984 were high in Long Island Sound, Harlem River, and Ja~aica Bay, and were moderate in all other branches. - Zinc concentrations ranged from 17 ug/1 in Kill Van Kull (K2) ~890 ug/1 in Mill Basin (J2). "Mid-way" East River stations (E3, E4, E5, H5), half of the Jamaica Bay stations, Hart Island (E10), and the Hudson River at 72nd Street (N3A) had high zinc concentrations, while Arthur Kills and Kill Van Kull stations had low zinc concentrations. Seventeen of the fifty-two stations had zinc concentrations in excess of the New York State standards while two stations had zinc concentrations equal to the standards. Zinc concentrations increased in six of the ten major branches this year over last year, i.e., Lower New York Bay, Lower East River, Upper East River, Long Island Sound, harlem River, and Jamaica Bay. Compared historically, zinc concentrations in 1984 were high in the East, Harlem, and Hudson Rivers, in Long Island Sound, and in Jamaica Bay; zinc concentrations were moderately low in New York Bay and the Kills. Further details are in Appendix E. - -6- MB~ALS: Sediment Concentrations Metal concentrations in sediments from New York Harbor are provided in Appendix F. The data indicate moderate to strong enrichment of trace metal concentrations in Harbor sediments as would be expected from water column metal concentrations. - Patterns of enrichment will not be discussed until data or sediment grain size is available. - Nutrients Ammonia nitrogen (NH3) concentrations ranged from 1.66 mg/1 at Fresh Kills to 0.19 mg/1 in the Lower New York Bay (N16). - Nitrate nitrogen (N03) concentrations ranged from 0.62 mg/1 at Spuyten Ouyvil to 0. 81 mg/1 at N9A and E 10. Nitrite nitrogen (N02) ranged from 0.14 mg/1 in the Raritan River to <0.005 (limit - of detection) at numerous stations. Ammonia nitrogen concentrations were exceptionally high (>1.0 mg/1) at Fresh Kills (K4), B & 0 RR Bridge (K3), Paerdegat - Basin (J10), and Spring Creek (J8). Moderately high NH3 concentrations (0.7 to 1.0 mg/1) were found at Tottenville (K5), Shooters Island (K2), Gowanus Channel (G2), Spuyten Duyvill (N2), - Hells Gate (E4), Flushing Bay to Throgs Neck (E6-8), westchester Creek (E13), Fresh Creek (J9), and Jamaica Bay RR Trestle (J5). Lowest concentrations (<0.3 mg/1) were found near the Atlantic Ocean (K6, H16, N9, N9A, J11 ), west of Manhattan (N2, N3B, N3A, - N4), the NW Harlem River (Hl & 2), and Little Neck Bay (E11). The "Oceanic" and Little Neck Bay stations had low nitrate as well as ammonia concentrations, but Hudson (W. of Manhattan) and - NW Harlem River stations had nitrate concentrations substantially greater than the ammonia concentrations. With the exception of the above sites, nitrate concentrations were generally less than ammonia concentrations. Nitrite concentrations were relatively - low at all stations. Total phosphorus concentrations ranged from 0. 355 mg/1 at - Flushing Bay s. (E15) to 0.044 mg/1 at N16. Dissolved ortho-phosphate ranged from 0.230 at Fresh Creek to 0.031 mg/1 at - N16. Highest concentrations of total phosphorus (>0.25 mg/1) were measured in samples ·form Bergen Basin, Fresh Creek, Paerdegat Basin, Little Neck Bay and Flushing Bay south. Lowest concen~ration of total phosphorus (<0.10 mg/1) were reported in samples from N16, N9, & N8. - Dissolved ortho-phosphate accounted for most of the phosphorus in Kill Van Kull, Arthur Kills, Raritan Bay and miscellaneous other stations. Dissolved ortho-phosphate accounted for about half of the phosphorus at most of the - remaining stations. Total organic carbon ranged from 2.0 mg/1 at Spuyten uuyvil - and N16 to 8.5 mg/1 at Flushing Bay. - -7- Compared historically, ammonia, nitrite, and total organic - carbon concentrations in 1984 tended to be moderately low to extremely low. Total phosphorus, and dissolved ortho-phosphate concentration in 1984 tended to be moderate in comparison to previous years, while nitrate concentrations were high to very - high. Fucther details are in Appendix G. - Oxygen Demand, Biochemical BOD tended to be greater in surf...n.:e waters than in bottom waters and generally ranged from two to three mg/1. Peak average values occurred in surface waters of Gowanus channel (4.6 mg/1 at G2), south Flushing Bay (4.3 at E15), Eastchester Bay (4.0 at E12), Bergen Basin (3.7 at J7), and Mills Basin (3.6 at J2). Low average values of less than 2 mg/1 were found in bottom waters at - K-1, 2, 3, 4, & 5: E-8, 9, 10: and G-1. Spatial patterns of BOD are interesting because high BOD's appeared to predominate in areas of very high or very low D.O. BOD increased in 1984 in all branches of the harbor, except in Long Island sound, Jamaica Bay, - and Arthur Kills. BOD has been generally increasing in the harbor since 1980. Further details are in Appendix B. - Bottom BOD had a weak direct correlation with bottom D.O. ( R= o. 24 ~ P=O. 0001 ) ; and a weak inverse correlation with water temperature (R=-0.15: P=0.0001) and time of day (R=-0.25; P=0.0001). Surface and bottom BOD had a moderate correlation - ( R=O .44; P=O. 0001 ) but surface BOD otherwise showed very weak relationships with all other variables. Further details are in - Appendix L. Plankton - Thirty five species of diatoms, seven species of green algae, and ten species of dinoflagellates were identified from one hundred sixty-seven samples of harbor waters. Total number of cells per ml ranged from 40 to 5800: species diversity (H1) - ranged from 0.46 to 1.67. Nannochlorus atomus (36\), Skeletonema costatum (28\), and Thalass10S1ra nordenskioldii (13\) were dominant in 77\ of the samples. N. atomus and s. costatum were also dominant species in the 1983-collections. -Further details ·- are in Appendix H. Temperature and Salinity Salinity in New York Harbor ranged from 9.4 ppt in surface waters of an upstream Hudson River station ( N2) to 30.7 ppt in bottom waters off Coney Island. A halocline exists inthe Hudson River transect above The Narrows caused by downstream flow of fresh surface water and upstream flow of saline bottom water. Salinity stratification apears to be non-existent in the East and - Harlem Rivers and minimal in the Kills and Jamaica Bay. Fresh flow from the Hudson River appears to determine Harlem River salinity and may, vial the Harlem River, serve to dilute the - Lower East River which obtains salinity from Long Island Sound. - - -8- Water temperatures were low in Long Island sound; moderating into the East River; higher in the Hudson River, Harlem River and - Jamaica Bay; and highest in the Kills. The thermocline was most pronounced in the Hudson River above the Battery, but was found at a majority of the sampling stations. water temperature does - not ident~fy water masses as well as does salinity, but tends to support t~e flow regimes indicated by salinity. Further details are in hppendix I. - Tidal Cycle Surveys Dissolved Oxygen, salinity, and total coliform concentrations were measured over tidal cycles at three limits of the harbor (Mt. St. Vincent, the Narrows, and Throgs Neck). Dissolved oxygen tended to increase during the afternoon, presumably due to photosynthesis, but did not show clear tidal - effects. Total coliform concentrations at the Narrows tended to increase slightly at low tide suggesting coliform inputs from the upper harbor. Coliform concentations at Throgs Neck and Mt. St. Vincent fluctuated, but did not show obvious effects of coliforms - from the harbor. Further details are in Apendix K. - Volatile organic Compounds Concentrations of volatile organic compounds in water column samples are provided in Appendix J. Of the twenty compounds considered, seven were rarely encountered ( 1, 1, 2, 2, - tetrichloroethane; n-propyl benzene; styrene; iso-propyl benzene; and 1, 2, dichloropropane), ethyl benzene was occasionally encountered; and the remaining twelve were usually encountered in - water samples. None of these substances is included in EPA or NYS-DEC standards. - Numerical Analysis Principal components analysis (PCA) based on covariances among the measured parameters indicates a strong contribution to - the overall variance from total coliform concentrations in surface waters. Bottom total coliforms and fecal coliforms also contributed significantly to data variance. The extremely wide range of coliform concentrations measured in Harbor water is the - cause of this covariance loading pattern. PCA based on the correlation matrix (Table) provides more - interesting results since these loading patterns are independent of the magnitude of measurement ranges. Principal component 1 (PC1) explains 24\ of the overall variance in the data and is based mainly on physical relationships between specific gravity, - temperature, and D.O. Interestingly, there is also a positive loading on PC1 from bottom BOD suggesting possible effects from increasing sediment oxygen demand as temperature decreases and/or - as salinity increases. PC2 explains an additional 14\ of the variance in the data and is based mainly on time-related effects. This component - shows that D.O. generally increased through the day, most likely - -9- - due to photosynthesis; but decreased as the sum~er. progr~s~ed, - possibly dJe to increased temperatures and/o.r b1ot1c act1v1t~. Interest in-:~1 y, this component suggests sl1ght decreases . 1n col iforms as time of day and as the season progressed, poss 1bly - due to in,:reased die-off rates as temperature increased. PC3 amplifies PC2, explains an additional 12\ of the - variance in the data, and is strongly controlled by "time-of-day" effects. Temperature and D.O. in•~ '"ased as time of day increased, while coliforms {especially in surface waters) decreased as time-of-day increased. Further details are in - Apendix L. - SUMMARY water quality in the New York Harbor over the past ten years h~s generally improved in terms of lead, nutrients {ortho-phosphate and ammonia), and dissolved oxygen, but has declined in terms of - chromium concentrations, though chromium concentrations were always within the acceptable range. Fluo:tuations in the levels - of other measured parameters mask any trends. Average 1984 DO concentrations in surface waters were in compliance with NYS-DEC standards at all stations except Gowanus Channel. Total coliform geometric mean concentrations exceeded - DEC standard values at 23 of the 52 stations while fecal coli forms exceeded the standards at only 4 of the 52 stat ions. Chromium concentrations were in compliance at 100\ of the - stations; cadmium at 92\; zinc at 63\; Nickel at 27\; Mercury at 11\; lead at 0\; and copper at 0\. Water column metal concentrations tended to be evenly distributed - among the branches of the harbor with the except ions of nickel and zinc. Nickel was most highly concentrated in Long Island sound, J arnica Bay, and the Harlem River. zinc was most highly concentrated in Jamaica Bay and the Lower East River. Dissolved oxygen tended to be less concentrated in bottom waters than in surface waters except at the Narrows and in the Upper New - York Bay where inverse DO stratification was consistantly measured. Surface DO was greatest in the Lower New York Bay, Jamaica Bay, Long Island Sound and the Hudson River with - concentrations dropping sharply in the Upper New York Bay, East River, Harlem River, and in the Kills. Total coliforms were least concentrated in Long Island Sound, Lower New York Bay, Jamaica Bay, and the Upper East River becoming progressively more -- concentrated in the Kills, the Hudson River, the Lower East River, . the Upper New York Bay, and the Harlem River , - respect1vely. - - -10- - A special study of the effects of effluent chlorination on - ambient coli form concentrations was performed in Jamaica Bay. Ambient coliform concentrations before the disinfection season were about one order of magnitude greater than during the disinfecti )n season. The effect of effluent disinfection was greatest tt stations having the highest coliform concentrations. - - - The City of New York Department of Environmental Protection - Bureau of Water Pollution Control Division of Plant Operations - - Report prepared by: - 7~~d~ Thomas L.
