The National Ground-Water Monitoring Network (NGWMN) started as 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 design for the National Ground-Water Monitoring Network is presented in the document 'A National Framework for Ground-Water Monitoring in the United States'.

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.

Funding to support data providers to the National Ground-Water Monitoring Network is  provided through  USGS Cooperative Agreements. Agencies can also find  information about the status of the  USGS cooperative agreements .
