Non-point Source Pollution

Non-point source (NPS) pollution (stormwater runoff) is defined as pollution that comes from many diffuse sources and is caused by rainfall or snow melt when it picks up and carries away natural and man-made pollutants and deposits them into lakes, rivers, and wetlands.

If we all do our individual parts in reducing non-point source pollution, together we can greatly improve the conditions of our lakes, rivers, and wetlands.
