Groundwater Use Databases

The Contaminant Fate and Transport team conducts research on the transport and fate of contaminants in groundwater through the unsaturated and saturated zones using innovative and proven USGS methods. The team's research focuses on the often complex processes that affect contaminant fate and transport, and includes expertise in wetland environments. Performing both field and laboratory studies to...

The U.S. Geological Survey (USGS) estimates water use by state, source of water, and category of use every 5 years. The withdrawals for Maryland, Delaware, and the District of Columbia are available in the tables below. In 2010, 1,472 million gallons per day (Mgal/d) of freshwater were withdrawn from surface water and groundwater sources in Maryland, 300 Mgal/d in Delaware, and 0.10 Mgal/d in the...

The Anacostia River has been subjected to dredging, filling, contamination, and other human influences for over 200 years. The result of these activities is that the river has been seriously degraded from its natural state. Many groups have been working to reduce the effects of environmental degradation on the water quality and living resources of the Anacostia River, primarily by focusing on...

The U.S. Geological Survey provides unbiased, timely, and relevant information, studies, and data about groundwater resources of the Nation. The USGS monitors groundwater levels in thousands of wells across the U.S. Hundreds of these wells are located in Maryland, Delaware, and the District of Columbia. The MD-DE-DC Water Science Center logs data on approximately 370 groundwater wells throughout...
