When groundwater is extracted from an aquifer, a cone of depression is created around the well.As the drafting of water continues, the cone increases in radius. Extracting too much water (overdrafting) can lead to negative impacts such as a drop of the water table, land subsidence, and loss of surface water reaching the streams.
The Center for Urban Environmental Research and Education (CUERE) is located at the University of Maryland, Baltimore County (UMBC) in Catonsville, Maryland. The center's focus is primarily on the relationship between natural and socioeconomic processes that occur in urban environments.
In 1973 it became the Center for Environmental and Estuarine Studies and in 1997 it assumed its current name. The center focuses on environmental research and education in Maryland, United States, with special attention to problems of the Chesapeake Bay , [ 1 ] [ 2 ] and includes climate research. [ 3 ]
Groundwater can be considered one of the last free resources, as anyone who can afford to drill can usually draw up merely according to their ability to pump (depending on local regulations). However, as seen in the figure, pumping-induced draw down causes a depression of the groundwater surface around the production well.
The Smithsonian Environmental Research Center (SERC) is a United States 2,650-acre (10.7 km 2) [1] environmental research and educational facility operated by the Smithsonian Institution. It is located on the Rhode and West Rivers near Edgewater in Anne Arundel County, Maryland , near the western shore of Chesapeake Bay .

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
The Leopold matrix is a qualitative environmental impact assessment method developed in 1971 by Luna Leopold and collaborators for the USGS. [1] It is used to identify and assign numerical weightings to potential environmental impacts of proposed projects on the environment. [1]
