Background Industrial discharges of toxic and bio-accumulating compounds to the Niagara River and its tributaries have occurred over many decades. High concentrations of polychlorinated biphenyls (PCBs) have been found in samples of fish tissue from many locations, including three tributaries to the Niagara River: Tonawanda Creek, Two mile Creek, and Rattlesnake Creek (study reaches listed in Table 1). Study site for SPMD sampler in a tributary to the Niagara River High PCB concentrations have also been found in mussel tissues during in situ experiments in the latter two creeks PCBs have been detected in sediments from many locations, but they were generally lower than expected given the elevated PCB concentrations...
Background The Esopus Creek is located in the Catskill Mountains of New York State and is part of the New York City (NYC) drinking water supply system. The basin was dammed in 1915 to form the Ashokan Reservoir splitting the creek into Upper (upstream of the reservoir) and Lower segments. The drainage area of Upper Esopus Creek, between the source (Winisook Lake) and the Ashokan Reservoir is approximately 192 mi2. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, also supplies water to Upper Esopus Creek (and to the Ashokan Reservoir) via the Shandaken tunnel. Waters from the Schoharie watershed enter Upper Esopus Creek at the Shandaken portal and travel 18 km before entering the Ashokan...

Background Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses may be impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The plankton (phytoplankton zooplankton) Beneficial Use Impairment (BUI) was so designated because impairment metrics were unavailable or inconclusive. Recent investigations, however, suggest that plankton communities are relatively healthy and no longer threaten the local ecosystem. Thus, the BUI for plankton may now be outdated in all, or parts of, the St. Lawrence River in the Massena AOC. The primary goal for the Massena (and Cornwall) Remedial Action...
Problem - Acidic precipitation has affected forested and aquatic ecosystems in New York, particularly in the Adirondack and Catskill regions. Acidification of surface waters and deleterious effects on fish and other biota have been well documented in both these regions. Despite reduced levels of acidity in atmospheric deposition over the past 20 years across New York and the northeastern United States, the most acid-sensitive streams and lakes have not yet begun to recover, and many show continued declines in acid-neutralizing capacity, an indicator acid-base status. Many studies have documented the effects of acid precipitation in New York, but thus far, there has been no comprehensive effort to synthesize and...
Background: Eighteenmile Creek was designated as an Area of Concern (AOC) in 1985 because water quality and bed sediments were contaminated by past industrial and municipal discharges, waste disposal, and pesticide usage. Five Beneficial Use Impairments (BUIs) were identified in the Eighteenmile Creek AOC, including BUI #3 - the degradation of fish and wildlife populations. The remedial action committee (RAC) for the Eighteenmile Creek AOC has identified the following removal criteria for this BUI: · Fish and wildlife diversity, abundance, and condition are statistically similar to diversity, abundance, and condition of populations at non-AOC control sites; AND · PCB levels in bottom-dwelling fish...
Background Watersheds of the Great Smoky Mountains National Park (GRSM) receive high levels of acid deposition resulting from atmospheric emissions of nitrogen and sulfur oxides. Acidic deposition has been shown to reduce acid neutralizing capacity (ANC) and calcium concentrations and increase acidity and aluminum concentrations in soils and surface waters and affect forest health as well as fish and macroinvertebrate assemblages across the GRSM. In fact, 12 streams on the Tennessee-side of the GRSM National Park are listed on the Clean Water Act’s 303d list of impaired surface waters for failing the pH standard (<6.0) as a result of atmospheric deposition of air pollutants (mainly nitrogen and sulfur). In the...

This project provides weekly wet-only mercury deposition samples at the Mercury Deposition Network (MDN) station in the Biscuit Brook watershed at the Frost Valley YMCA. The station has been in operation since 2004 and is currently funded by New York State Energy Research and Development Authority (NYSERDA). This is the only MDN station located in the Catskill Mountains and one of only 3 stations in New York State. The Catskill Mountains supply 85% of New York City’s drinking water through a system of surface water reservoirs. All of these reservoirs have fish consumption advisories because of the high level of mercury (Hg) in fish in the reservoirs and atmospheric Hg deposition is the main source of Hg to the...
BACKGROUND Watersheds of the Adirondack Mountains receive high levels of acid deposition resulting from atmospheric emissions of nitrogen and sulfur oxides. Acidic deposition has been shown to reduce acid neutralizing capacity (ANC) and calcium (Ca) concentrations, and increase acidity and aluminum (Al) concentrations in soils and surface waters, and affect forest health as well as fish and macroinvertebrate assemblages across the region. The U.S. Environmental Protection Agency (EPA) is currently developing secondary standards for nitrogen and sulfur emissions that will indirectly protect terrestrial and aquatic species and their communities from further adverse impacts and promote recovery of acidified ecosystems...
Problem The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern NY. Waters throughout upper reaches of both rivers currently range from neutral to severely acidic due to deposition of acid rain throughout their watersheds. Fish surveys conducted by the USGS during the late 1980s and early 1990s found that some fish species and entire assemblages were absent or depressed in many tributaries and second and third order reaches of both rivers. Recent decreases in acidity of atmospheric deposition and changes in hydrologic and thermal regimes are now affecting water chemistry (e.g., pH, acid neutralizing capacity, dissolved organic...

Background Acidification of lotic and lentic environments has been found to adversely affect the integrity of resident biological assemblages. These effects have been particularly severe in poorly buffered regions like the Western Adirondacks. Although the Clean Air Act and its amendments have greatly reduced levels of atmospheric deposition, many streams in this region are still chronically or episodically acidified. In-stream and watershed-wide liming are two directed-mitigation techniques which could be used to accelerate ecosystem recovery and help restore the condition of biological assemblages. The costs and abilities (as well as effective duration) of these techniques to improve water and soil chemistry,...

Background Fish communities of the mainstem Mohawk River and Barge Canal have been well-documented (Carlson, 2015; George et al., 2016) but comparatively less information is available regarding the current status of fish communities in tributaries to the Mohawk River. This information gap is problematic because long-term shifts in species distributions or abundances due to climate change, eutrophication, or other anthropogenic stressors may go unnoticed in the absence of baseline data. More importantly, an approaching invasive fish species, the Round Goby (Neogobius melanostomus), is expected to colonize much of the Mohawk River and the lower portion of many major tributaries. Introductions of Round Goby have had...

The U.S. Geological Survey (USGS) is collaborating with the New York Department of State (NYDOS) Office of Planning and Development to prepare a new Long Island South Shore Estuary Reserve (SSER) Coordinated Water Resources Monitoring Strategy (CWRMS). Since 2000, when the last CWRMS was published, numerous research projects and studies are demonstrating several new threats to the ecologic health and resilience of the SSER. Contemporary threats include: Eutrophic conditions brought on by high levels of nutrients from sewage treatment plant discharges, stormwater runoff, groundwater seepage, and atmospheric contributions; Increased occurrences of harmful algal blooms in the past 15 years; and, Growing concern...
The growth of temperate forests is typically limited by the availability of nitrogen. Elevated concentrations of nitrate in some Catskill Mountain streams, which are tributary to New York City's water-supply reservoirs west of the Hudson River, indicate that the forests of this region are at the early stages of nitrogen saturation. That is, nitrogen is available in excess of the amount utilized by vegetation and soil microorganisms in the forests. Nitrogen saturation is a concern because the mobile nitrate that moves through soil is accompanied by other nutrients such as the base cations calcium and magnesium that are necessary for forest growth but are present in short supply in some Catskill soils. And, nutrient...
Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal trends and potential recovery of fish assemblages in less acidic or less toxic streams. Though the effects of acidification on fish assemblages have been qualified in several streams of the eastern Adirondacks during 1979, the 1980s, and early 2000s, (Schofield and Driscoll 1987; Simonin et al. 2005) quantitative impacts were...

The Ellison Park wetland, a 423-acre, predominantly cattail marsh at the mouth of Irondequoit Creek in Monroe County near Rochester, N.Y., was evaluated for its potential role to decrease phosphorus loads that are derived from a 151-square-mile largely urbanized area and that ultimately enter and exacerbate efforts to ameliorate the eutrophic conditions in Irondequoit Bay. Monroe County's water-quality management plan included (1) modification of flow patterns upstream from and within the wetland by diverting storm runoff into backwater areas of the wetland, and (2) construction of a flow-control structure midway through the wetland that would cause short-term rises in water levels and increased dispersion of...

Problem The Adirondack region of New York has 128 lakes that are listed as impaired by acidity under section 303(d) of the Clean Water Act. Acidity can limit the survival and reproduction of native fishes such as brook trout (Salvelinus fontinalis). Chronic and episodic acidification also stresses fish, aquatic macroinvertebrates, and other biota of inflowing tributaries of these and many additional lakes. Acidification of these tributaries can also affect the health of fish populations in receiving lakes, by limiting suitable spawning and nursery habitat. Although many Adirondack lakes have shown decreased acidity resulting from decreases in atmospheric sulfur and nitrogen emissions, the ecological improvements...
Problem Over the past century, the Harlem River watershed has become highly urbanized with 90 percent of the waterway constrained by infrastructure, which has limited access for recreational use. Bound by New York (Manhattan) and Bronx Counties, the Harlem River is a tidal strait between urbanized estuaries to the north (Hudson River) and south (East River). Direct inputs include the more than 50 combined sewer overflows (CSOs) that discharge runoff from impervious surfaces and untreated sewage to the Harlem River during precipitation events. Historic uses of the Harlem River included swimming, boating, and fishing, as well as horseback riding and hiking through adjacent parklands. As urban sprawl continued...
Background: The USGS propose a collaborative investigation with the NYSDEC and NOAA to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Niagara River Area of Concern (AOC). Using a probabilistic study design, sediment-toxicity data compiled by the USGS, invertebrate community data collected by NYSDEC, and sediment-chemistry data collected by NOAA will be assimilated using a Sediment Quality Triad approach (Chapman et al., 1992; USEPA, 1992) to provide a sediment-quality baseline needed to gauge changes expected to follow remediation of contaminated sediments in parts of the AOC. These data will also be used directly to confirm that the macroinvertebrate...

Background Discharges from non-point sources, municipal and industrial point sources, and combined sewage overflows over the last century resulted in elevated levels of heavy metals, conventional pollutants, phosphorus, and toxic organic contaminants in water and sediments of the Lower Genesee River and Rochester Embayment. As a result, the zooplankton and phytoplankton or “plankton” communities were designated as one of fourteen Beneficial Use Impairments (BUI); i.e., the resource was either impaired or in need of assessment in the Rochester Embayment Area of Concern (AOC). The Rochester Embayment Remedial Action Committee (RAC) was formed by the New York State Department of Environmental Conservation (NYSDEC)...
Problem - There is a stated need to provide information on loading of persistent toxic pollutants to Lake Ontario from New York tributaries. The information is specifically required for the Lake Ontario Mass Balance Model, which is an integral part of the long-term Great Lakes research. The project described here is designed to demonstrate a cost-effective approach for estimation of loads of polychlorinated-biphenyls (PCBs) through use of a relatively small number of large-volume whole-water samples for PCB analysis. The Black River basin was selected to demonstrate the feasibility of the approach because it is the largest New York contributor of PCBs to Lake Ontario. Objectives - The objective of this project...
