USGS Recognizes "National Groundwater Awareness Week"
The USGS conducts groundwater activities in every state and in the US territories. Recent activities around the Nation include:
USGS New England Water Science Center - Massachusetts staff analyze groundwater samples at the USGS Toxic Substances Hydrology Program research site at Massachusetts Military Reservation.
Improved our understanding of how pumping groundwater wells can affect streams.
This information can be used by scientists and water resource managers to estimate the rate, locations, and timing of streamflow depletion in response to groundwater pumping. Learn more in the new factsheet.
Added spring data to our popular Groundwater Watch.
The Active Springs Monitoring Sites web pages provide data from more than 100 springs in the USGS active measurement program.
Produced a national assessment and on-line interactive maps of groundwater-quality trends,
showing how contaminant concentrations have changed over the last twenty years. View the maps and learn more.
Created the first the first comprehensive groundwater flow model for the entire Yakima River in Washington.
Tribal, State, and Local agencies use the model estimates to inform their management of water resources and to protect streamflows for sockeye salmon and other critical aquatic species. A detailed report about the study is online.
Documented for the first time the occurrence of groundwater that is more than a million years old in a major water-supply aquifer along the Atlantic Coast.
USGS findings revealed that modern pumping in southern Maryland west of the Chesapeake Bay and on the Eastern Shore is tapping groundwater resources that have accumulated in the aquifer over multiple cycles of climate change and are not quickly recharging. A detailed journal article explains the USGS research.
Continued Development of a Collaborative National Groundwater Monitoring Network.
Through the Advisory Committee on Water Information Subcommittee on Ground Water, and in partnership with other federal agencies, state agencies, and non-governmental organizations, the USGS continued development of a collaborative National Groundwater Monitoring Network.
Collaborated with the U.S. Environmental Protection Agency to create a new online portal that includes both USGS and EPA water-quality data.
Stakeholders can access over 150 million water-quality records at the Water Quality Portal (WQP).
