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...
Assessment of Hydrologic and Water-Quality Changes in Shallow Groundwater Beneath a Coastal Neighborhood Being Converted from Septic Systems to Municipal Sewers
The U.S. Geological Survey and the U.S. Environmental Protection Agency are collaborating on a study to better understand changes to groundwater quality beneath a densely developed coastal neighborhood as it undergoes conversion from onsite wastewater disposal to municipal sewering.
Groundwater and Surface-Water Monitoring in the Mill Creek Watershed, Wellfleet and Truro, Massachusetts
The Herring River estuary and salt marsh system, within the Cape Cod National Seashore in Wellfleet, Massachusetts, has been diked off from the ocean for more than 100 years. The National Park Service is now preparing to restore the 1,100 acre estuary-marsh system.
Characterization of Water Quality in the Sakonnet River, Rhode Island, 2018-19
Sections of Narragansett Bay and its eastern arm, the Sakonnet River, are considered impaired for shellfishing, aquatic habitat and recreational use by the State of Rhode Island. Aquatic habitat and water quality in the western portions of Narragansett Bay are relatively well understood, but there is comparably limited information available in the Sakonnet River. To address concerns about the lack...
