What is NPS Pollution
Nonpoint source (NPS) pollution comes from many sources in both urban and rural areas. Runoff from cropland, parking lots, lawns, mines, and septic systems often contribute to NPS pollution. NPS pollutants are transported to the surface and ground water by precipitation. During large storms, the runoff to surface water and infiltration to ground water increases and so does the rate of NPS movement (or transport).

About NPS Investigations
The study of nonpoint source pollution in Ohio has been an ongoing effort for state, local, and federal governmental agencies. The Ohio Department of Natural Resources, Division of Water has participated in several projects funded by grants under Section 319 of the Clean Water Act of 1987. These funds are awarded by the United States Environmental Protection Agency (U.S. EPA) to study nonpoint source pollution in Ohio. Since 1990, this program has used federal funds at the state level to support projects that study and help reduce nonpoint pollution. Projects are awarded to non-profit organizations or agencies that can provide a 40% match for the federal funds appropriated. The products of these studies are a series of reports that are available from the Division of Water.
