Managing Polluted Runoff in Mississippi

When water from rainfall flows across the landscape, it can wash soil particles, bacteria, pesticides, fertilizer, pet waste, oil and other toxic materials into our lakes, streams and groundwater. This Nonpoint Source (NPS) Pollution is difficult to control because it comes from a diverse number of activities including fertilizing lawns and farm fields, driving and maintaining our cars, constructing buildings and roads, plowing our fields for crops, and harvesting trees.

The Mission of Mississippi’s Nonpoint Source Program

To conserve and improve State waters, for man’s use and the sustainment and propagation of wildlife and aquatic life, through focused research, responsible regulation, widespread education, and cooperation with other agencies and the public.


Nonpoint source pollution--or polluted runoff-- is the leading cause of water quality problems in Mississippi.
