Definitions for "Non-point source pollution"
Pollution generated by diffuse land use activities rather than from an identifiable or discrete facility. It is conveyed to waterways through natural processes, such as rainfall, storm runoff, or groundwater seepage rather than by deliberate discharge. Non-point source pollution is not generally corrected by "end-of-pipe" treatment, but rather, by changes in land management practices.
pollution from diffuse sources that cannot be attributed to one identifiable point, such as a discharge pipe.
Source of pollution in which wastes are not released at one specific, identifiable point but from a number of points that are spread out and difficult to identify and control
nutrients or toxic substances that enter water from dispersed and uncontrolled sites.
