USGS Regional AquiferSystem Analysis (RASA) studies were conducted between 1978 and 1995 to define the regional geohydrology of the Nation's important aquifer systems. Maps showing dissolvedsolids concentrations were published for many of these aquifer systems and compiled for the USGS Ground Water Atlas of the United States ( Geological Survey, 2000).
