National Ground-Water Monitoring Network

The National Ground-Water Monitoring Network (NGWMN) is a product of the Subcommittee  on Ground Water   of the Federal Advisory Committee on Water Information (ACWI). The  NGWMN is a compilation of selected groundwater monitoring wells from Federal, State, and  local groundwater monitoring networks across the nation.

The NGWMN Data Portal provides access to groundwater data from multiple, dispersed  databases in a web-based mapping application. The portal contains current and historical data  including water levels, water quality, lithology, and well construction. The NGWMN is currently  in the process of adding new data providers to the Network. Agencies or organizations collecting  groundwater data can find out more about becoming a data provider for the Network here.

Funding to support data providers to the National Ground-Water Monitoring Network is  provided through USGS Cooperative Agreements. Information about the latest status of the  USGS cooperative agreements is available here.
