| Groundwater and Streamflow Information Program, National Ground-Water Monitoring Network | The United States Geological Survey (USGS) Groundwater and Streamflow Information Program is offering cooperative agreement funding to government and Tribal agencies that collect groundwater data, to support participation in the National Ground-Water Monitoring Network (NGWMN). The funding supports connecting new data providers to the NGWMN and helping existing providers maintain reliable, long-term data services and improve their data contributions. The NGWMN is designed to be a compilation of selected wells and springs from existing monitoring efforts to create a network to assess long-term water-level and water-quality trends at a national scale. USGS will provide guidance to existing data providers on techniques for collection of site information, on well maintenance activities, and on well drilling to support development of the NGWMN. Therefore, these awards will be in the form of cooperative agreements. This funding supports projects that help build and maintain a national network for tracking groundwater levels and quality. Specifically, it covers connecting new agencies to the network by setting up digital data sharing services and maintaining those connections for existing partners. | State Government Local Government, including Acequias Federal Recognized Tribes/Pueblos | • City or township governments • Federally recognized Native American tribal governments • County governments • State governments • Special district governments | Water Administration Capacity/Technical Assistance | $300,000 | $5,000 | 3/26/2026, 8:00:00 PM (UTC) | Open | Federal | US Geological Survey | Sara Roser, sroser@usgs.gov | https://www.grants.gov/search-results-detail/361219 | ||
