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.
In 2016, 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 water-quality projects joined to form the NWQP.
Welcome to the National Water Quality Program (NWQP), where we collect data and provide information about the quality of our Nation’s water resources to support science-based policies and effective management strategies.
