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.
Water Quality Data Collection to Support Aluminum Criteria Development in Massachusetts
The U.S. Geological Survey (USGS) and Massachusetts Department of Environmental Protection (MassDEP) are collaborating on a study to collect water-quality data at streams and ponds in Massachusetts that receive aluminum discharges from wastewater treatment (WWTF) or public-water supply (PWS) facilities. The objective of this study is to inform the development of MassDEP guidelines on discharge...
NorEaST: A Tool to Understand the Responses of Fish to Changes in Stream Temperature
Climate change is expected to alter stream temperature and flow regimes over the coming decades, and in turn influence distributions of aquatic species in those freshwater ecosystems. To better anticipate these changes, there is a need to compile both short- and long-term stream temperature data for managers to gain an understanding of baseline conditions, historic trends, and future projections.
