Nonpoint Pollution

pollution

There are many ways to categorize pollution, one of those ways is dependent on the source of pollution, or how the pollution enters the system. The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, 1997). "Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. 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 ground waters. (EPA)"5_9_waterpolChart

Nonpoint pollution is the nation’s number 1 water quality issue. Pollutants like soil, lawn chemicals (pesticides, herbicides, fertilizers), salt, and petroleum products from driveways, parking lots and roads are rinsed off the earth’s surface by rain or melting snow.

Storm water runoff that does not soak into the ground rushes to local streams and lakes causing damage to habitat with pollution, erosion and water that has been warmed by running over pavement.
