Project Contact(s)

The DGS has been a data provider for the National Ground-Water Monitoring Network (NGWMN) since 2016. NGWMN is a consortium of state and local agencies and the U.S. Geological Survey (USGS) that was established in 2013 to create a single web portal for scientists, engineers, policy makers, and the public to view and acquire important physical and chemical data on the nation’s groundwater resources. The network allows users to view both state- and federally-collected groundwater data to evaluate current status and trends in groundwater quality and availability in a local, regional or national context. NGWMN resources are managed by the USGS Center for Data Analytics and can be accessed at

DGS staff members Changming He, Tom McKenna, Rachel McQuiggan, Steve McCreary, and David Wunsch participate in DGS efforts to maintain the monitoring well infrastructure and to collect, manage, and distribute data to the NGWMN. Resources provided by the USGS will help to modernize and improve state-led monitoring activities.
