Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for swimming on the basis of the previous day’s E. coli concentration. Sanitary conditions may change overnight and even throughout the day (Boehm and others, 2002) making decisions made from previous days information incorrect.

Typically, the amount of nitrate in groundwater is related to land use, where the greatest concentrations are observed in agricultural regions. In many areas, the nitrate concentration has increased steadily in recent years, even in areas that are no longer farmed and are now sewered. A statistical analysis for trends of over 20 years in nitrate concentration data from SCWA wells is needed to determine the susceptibility of supply-wells to exceed the Maximum Contaminant Level (MCL) for nitrate.

Systematic sampling of water wells for dissolved methane is needed to determine if the topographic and hydrogeologic setting of a well is related to methane occurrence. Objective and Study Area - The objective of this study is to characterize the natural occurrence of dissolved methane gas in groundwater from water wells within four different topographic and hydrogeologic settings (upland and major valley areas where bedrock is confined or unconfined by glacial deposits)....

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...

Onondaga County Soil and Water Conservation District (SWCD) has promoted best-management practices to decrease loads of nutrients and sediment from agricultural lands. Onondaga County Department of Water Environment Protection has abated many of the outflows from combined sanitary-and-storm sewers in the city of Syracuse and has upgraded treatment capabilities for removal of nutrients in effluent from the county's Metropolitan waste-water-treatment plant.

Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...

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...

The mixed land uses (residential, commercial, industrial, agricultural, and recreational) of Nassau County contribute point and non-point sources of aquifer contamination. Nassau County water purveyors currently operate supply wells screened in the upper glacial, Magothy, and Lloyd aquifers. The protection and long-term sustainability of all three aquifers are vital concerns for the Nassau County Department of Public Works (NCDPW).

Thus it is not surprising that associated effects on surface-water quality and ecosystems in lakes and streams of the southwestern Adirondack Mountains of New York were investigated to various extents over the past 35 years; first to document acidification effects and then to evaluate potential recovery. In fact, evidence of adverse impacts on water quality and aquatic ecosystems across the region provided much support for implementation of the Clean Air Act (CAA) of 1990.
