Regional Aquifer System Analysis Program

Project Description
Regional Aquifer System Analysis Program (RASA) is a National Program
which reports provide the results of studies of regional groundwater
systems. The studies concern the occurence, movement, and quality of
groundwater in major aquifer systems.

The objective of the RASA Program is to define the regional
geohydrology and establish a framework of background
information--geologic, hydrologic, and geochemical--that can be used
for regional assessment of ground-water resources and in support of
detailed local studies.

The project began in 1978 and was completed in 1995.
