Nonpoint source pollution definition

Nonpoint source pollution means pollution such as sediment, nitrogen, phosphorous, hydrocarbons, heavy metals, and toxics whose sources cannot be pinpointed but rather are washed from the land surface in a diffuse manner by stormwater runoff.
Nonpoint source pollution means a form of water pollution that does not originate from a discrete point such as a wastewater treatment facility or industrial discharge, but involves the transport of pollutants such as sediment, fertilizers, pesticides, heavy metals, oil, grease, bacteria, organic materials and other contaminants from land to surface water or groundwater via mechanisms such as precipitation, stormwater runoff, and leaching. Nonpoint source pollution is a by-product of land use practices such as agricultural, silvicultural, mining, construction, subsurface disposal and urban runoff sources.
Nonpoint source pollution means pollution such as sediment, nitrogen, phosphorus, hydrocarbons,

Examples of Nonpoint source pollution in a sentence

  • Nonpoint source pollution generally involves a buildup of pollutants on the land surface that wash off during rain events and as such, represent contributions from diffuse sources, rather than from a defined outlet.

  • Nonpoint source pollution, by contrast, comes from many diffuse sources not subject to NPDES permitting.

  • Nonpoint source pollution refers to runoff that enters surface waters through stormwater runoff, contaminated ground water, snowmelt or atmospheric deposition.

  • Nonpoint source pollution requires state watershed-oriented water quality management plans, and federal agencies should collaborate with states to carry out the objectives of these plans.

  • Nonpoint source pollution within the recharge area of Tumbling Creek cave is also a threat to the species (Aley and Ashley 2003, p.19; U.S. Fish and Wildlife Service 2003, pp.
