Does USGS regulate drinking water?
No. The U.S. Geological Survey (USGS) is a non-regulatory agency under the U.S. Department of Interior and is the primary Federal agency responsible for providing scientific information on the quality of the Nation’s water resources. USGS information is intended to facilitate effective management of water resources and ensure long-term availability of water that is safe for drinking and recreation and is suitable for industry, irrigation, and fish and wildlife.
