Groundwater Sustainability of the Long Island Aquifer System
The U.S. Geological Survey (USGS) has partnered with the New York State Department of Environmental Conservation (NYSDEC) to conduct a comprehensive study of the Long Island aquifer system. The major findings of this investigation include: The location of the boundary between fresh and salty groundwater is much closer to the shoreline than previously thought. The historical onshore saltwater...

Water Quality Sampling and Monitoring of the Pawcatuck River Watershed
The Pawcatuck River and the Pawcatuck River Estuary and Little Narragansett Bay form part of the boundary between the States of Connecticut and Rhode Island. Both states have identified water quality impairments within these waters related to nutrients (insufficient oxygen) and bacteria. Studies of the eutrophication potential of Long Island Sound embayments have identified that the Pawcatuck...
Surface Water Quality Monitoring in Connecticut
The 2,983 miles of streams in Connecticut support a range of uses, including drinking water, recreation, and fish and shellfish habitat. The State is required by the Clean Water Act to assess the health of these waters every two years.
Comprehensive Delineation of Groundwater Source Areas and Times-of-travel to Long Island Streams and Estuaries
Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an...
