Research on Per- and Polyfluoroalkyl Substances (PFAS) in the New England Water Science Center

Per- and polyfluoroalkyl substances (PFAS) are a diverse group of over 4,000 different compounds. Since the 1940s, PFAS have been manufactured and used around the globe, including in the United States. PFAS are resistant to chemical and thermal breakdown and impart stain and water-resistance properties, making them useful for a variety of commercial applications, but also persistent in the...

Water Quality Sampling in the Tributaries of the Long Island Sound

Coastal estuaries in southern New England and New York show the effects of excess nutrients and coastal eutrophication. These include excessive growth of macroalgae, excessive blooms of phytoplankton, oxygen depletion, hypoxia and deteriorated substrates. State and Federal regulators have responded to these nutrient-caused impairments by requiring more stringent permit limits for National...

Chloride Data for Streams in Connecticut, Massachusetts, and Rhode Island

As part of water-quality data collection activities in New England, water samples are analyzed for chloride in monitoring networks and projects across Connecticut, Massachusetts, and Rhode Island. Chloride is of interest because high concentrations may affect aquatic life in streams or affect water quality of reservoirs and aquifers used for drinking water.

Measurement and Modeling of Nitrogen Discharge to Cape Cod Rivers to Identify High-Priority Nitrogen Reduction Areas

In 2019 USGS and the U.S. Environmental Protection Agency (EPA) Region 1 initiated a study to measure spatial and temporal patterns of nitrogen loading in selected rivers on Cape Cod and then determine whether the measured patterns can be related to nitrogen source areas in the surrounding watersheds to prioritize nitrogen reduction efforts. Study results will improve understanding of nitrogen...
