  "definition": "1. Nonpoint Source: Any source of pollution not associated with a distinct discharge point. Includes sources such as rainwater, runoff from agricultural lands, industrial sites, parking lots, and timber operations, as well as escaping gases from pipes and fittings. (Environmental Issues Glossary) Nonpoint Source Pollution: Pollution sources which exhibit any of the following characteristics: are diffuse, do not have a single point of origin, or are generally carried off the land by stormwater runoff. (TX NRCC Local Gov Guide) Nonpoint Source Pollution: Pollution sources that are diffuse, without a single identifiable point of origin, including runoff from agriculture, forestry, and construction sites. (Contaminated Sediment Glossary) Nonpoint Sources: 1: Diffuse pollution sources (i.e., without a single point of origin or not introduced into a receiving stream from a specific outlet). The pollutants are generally carried off the land by storm water. Common non-point sources are agriculture, forestry, urban, mining, construction, dams, channels, land disposal, saltwater intrusion, and city streets. (TofE)\n\n2. Water pollution caused by rainfall or snowmelt moving over and through the ground which carries pollutants. A nonpoint source is any source of water pollution that does not meet the legal definition of point source in section 502(14) of the Clean Water Act.\n\n3. Pollution that is not released through pipes but rather originates from multiple sources over a relatively large area. Nonpoint sources can be divided into source activities related either to land or water use including failing septic tanks, improper animal-keeping practices, forestry practices, and urban and rural runoff.\n\n4. Pollution sources that are diffuse, without a single identifiable point of origin, including runoff from agriculture, forestry, and construction sites.\n\n5. Nonpoint Source pollution is a pollution source without a single point of origin or specific outlet. NPS pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. 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.\n\n6. Pollution source without a single point of origin or specific outlet.\n\n7. Pollution originating from diffuse areas (land surface or atmosphere) having no well-defined source.\n\n8. Pollution resulting from intermittent discharges of pollutants from diffuse sources and is in transit over land before entering a water body.",
