Peters Creek Nonpoint Source Pollution

Peters Creek Nonpoint Source Pollution

What is Nonpoint Source Pollution?

Here is the Environmental Protection Agency's answer:

Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water. These pollutants include:

  • Excess fertilizers, herbicides, and insecticides from agricultural lands and residential areas;

  • Oil, grease, and toxic chemicals from urban runoff and energy production;

  • Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks;

  • Salt from irrigation practices and acid drainage from abandoned mines;

  • Bacteria and nutrients from livestock, pet wastes, and faulty septic systems;

  • Atmospheric deposition and hydromodification are also sources of nonpoint source pollution.
