National Water Quality Program

About

The National Water Quality Program (NWQP) is one of four Water Investigations Programs funded by Congress to identify, measure, and assess the Nation’s water resources. The NWQP is the principal USGS Program for monitoring the quality of the Nation’s freshwater resources including streams, rivers, lakes, reservoirs, and groundwater.

The National Water Quality Program (NWQP) brings together four large projects that evaluate the quality of our Nation’s waters: the National Water Quality Assessment (NAWQA) Project, the National Atmospheric Deposition Program (NADP), the USGS-National Park Service (USGS-NPS) Water-Quality Partnership, and cooperative projects.
