The National Groundwater Monitoring Network (NGWMN) is a compilation of selected groundwater monitoring wells from Federal, State, and local groundwater monitoring networks across the nation. The NGWMN is designed to be a curated network of wells that are of known quality and can provide insight to groundwater araciality. The NGWMN Data Portal provides access to data in the Network; monitoring locations must be added to the network through a manual process. Each Water Science Center can select wells they deem appropriate for inclusion in the NGWMN. This session will cover criteria for wells to include in the NGWMN, give tips on how to determine if wells should be added or deleted, and review the application that can be used for this process.
