Trends in Nitrate Concentrations in Public Water-Supply Wells, Suffolk County, New York, 1982-2008 Introduction High nitrate concentrations are a common concern among many purveyors, including the Suffolk County Water Authority (SCWA), the largest supplier of water to residents in Suffolk County. 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. This information is essential...

The existing science being used to inform decisions on remediation is biased toward activities are necessarily focused on the immediate aftermath of storms An assessment of the sources of contaminants that may have been introduced from inundation is needed to provide a context with which the Tribal community can better understand how to prioritize and manage the sources and minimize risk. Objectives This project will evaluate key human- and ecological-health concerns related to transport and persistence of...

An extensive ground-water and surface-water monitoring program is necessary to provide a comprehensive hydrologic data set for use in ongoing and future ground-water investigations. Objective The project will provide a continuous hydrologic data set needed for resource assessment, planning, and protection. To meet this objective the U.S. Geological Survey (USGS), in cooperation with the New York City Department of Environmental Protection, maintains and operates a network of approximately...
