Effects of Sea-Level Rise and Climate Change on the Groundwater-Flow System of Martha’s Vineyard, Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Department of Environmental Protection (MassDEP), is investigating the effects of sea-level rise and climate change on the groundwater resources of Martha’s Vineyard, Massachusetts.
Water Quality Monitoring of Merrimack River Watershed
The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection (MassDEP), is currently conducting a 4-year water-quality investigation in the lower portion of the Merrimack River watershed, April 2020 – October 2024.
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...
Flood Documentation and Inundation Mapping of the January and March 2018 Nor’easters in Coastal Massachusetts
2018 Nor’easters in Coastal Massachusetts
Embayment Monitoring to Support Nutrient Management Activities in Connecticut for Long Island Sound
The USGS, in cooperation with the Connecticut Department of Energy and Environmental Protection will be collecting water-quality and hydrologic data at four embayments from April 2021 to March 2025: Mystic, Norwalk, Saugatuck, Sasco-Southport complex, and Farm.
Remembering Tropical Storm Irene in New England
On August 28, 2011 Tropical Storm Irene made landfall in New England, leading to coastal storm surge, significant riverine flooding, sediment transport to Long Island Sound, and major infrastructure damage and destruction. Ten years later, the USGS New England Water Science Center looks back at Irene, the data collected by our Center during the event, the response by our employees before, during...
Assessment of Nutrient Transport and Discharge to Coastal Embayments, Wickford, Rhode Island
In 2020 the USGS began a partnership with the U.S. Environmental Protection Agency (EPA) Region 1 Southeast New England Program for Coastal Watershed Restoration (SNEP) and EPA Office of Research and Development (ORD), Atlantic Coastal Sciences Division, Narragansett, RI in support of water-quality and ecological monitoring being conducted by ORD in the coastal waters around Wickford, RI. The USGS...
Monitoring Merrimack River Mainstem and Tidal Reaches in Massachusetts to Evaluate Water Quality Conditions, May to September 2020
The Merrimack River watershed, the 4th largest watershed in New England (Massachusetts Executive Office of Environmental Affairs, 2001), has seen substantial growth and development in recent years.
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...
Development of a Water Quality Monitoring Strategy for Mount Hope Bay and the Taunton River Estuary, Massachusetts
The U.S. Geological Survey (USGS) and Massachusetts Department of Environmental Protection (MassDEP) are collaborating on a study to develop a water quality monitoring strategy for Mount Hope Bay and the Taunton River Estuary.
Development of a Regional-Scale Model to Simulate Groundwater Flow and Nitrogen Loading in Watersheds Along the Connecticut Coast of Long Island Sound
In 2018 USGS began work on the development of regional-scale groundwater flow and nitrogen transport models of areas along the Connecticut coast. The model will be used as a quantitative tool to evaluate groundwater flow and nitrogen loading to Long Island Sound.
Hydrologic Site Assessment for Passive Treatment of Groundwater Nitrogen with Permeable Reactive Barriers, Cape Cod, Massachusetts
In 2019 USGS completed a study designed to develop and evaluate a phased site-assessment approach for determining the hydrologic suitability of sites being considered for permeable reactive barrier installation on Cape Cod. The approach provides a template for town officials and other stakeholders to follow when considering PRBs for passive treatment of nitrogen in groundwater on Cape Cod and...
