Groundwater is not a single vast pool of underground water; rather, it is contained within a variety of aquifer systems. Each of these aquifers has its own set of questions and challenges. From large drawdowns in the Great Plains aquifer to arsenic in some wells in New England, this episode of CoreCast highlights six different USGS groundwater studies all across the United

Development can have negative effects on streams in urban and suburban areas. As a watershed becomes covered with pavement, sidewalks, and other types of urban land cover, stream organisms are confronted with an increased volume of storm water runoff, increased exposure to fertilizers and pesticides, and dramatic changes in physical living spaces within the stream itself.

USGS scientists measured the concentrations of select endocrine disrupting chemicals (EDCs) in Spirit Creek, Georgia, as part of an assessment of the effects of the closure of a wastewater treatment plant. Sprit Creek is typical of a stream in coastal environments.

Scientists from the USGS South Atlantic Water Science Center are sampling Sope Creek, Cobb County, west of Atlanta, Georgia. 

Chemical and physical consituents can vary from bank to bank even in a small creek like this. Just taking a single sample from a chosen horizontal and
