USGS Groundwater Programs
The Groundwater Resources Program (GWRP) is one of eight Water Resources Investigations Programs funded by Congress to identify, measure, and assess the Nation’s water resources. The GWRP is the principal USGS Program for assessing issues related to groundwater resources at the regional scale.
The National Research Program (NRP) conducts basic and problem-oriented hydrologic research in support of the USGS mission. The NRP is designed to encourage pursuit of a diverse agenda of research topics aimed at providing new knowledge and insights into varied and complex hydrologic processes that are not well understood.
The Toxic Substances Hydrology Program provides objective research and scientific information on environmental contamination to improve characterization and management of contaminated sites, to protect environmental health, and to reduce potential future contamination problems. The Program produces new analytical methods, scientific simulation models, and an understanding of the physical, chemical and biological processes that control contaminant source loading, transport, and transformation in the environment.
The National Water-Use Information Program compiles and disseminates the Nation's water-use data. The USGS works in cooperation with local, State, and Federal environmental agencies to collect water-use information. USGS compiles these data to produce water-use information aggregated at the county, state, and national levels.
The National Water-Quality Assessment (NAWQA) Program describes the status and trends in the quality of a large representative part of the Nation's groundwater and surface-water resources, and develops an understanding of the natural and human factors affecting the quality of these resources.
