Detailed explanation-1: -Point source pollution is a single identifiable source of pollutants (Lapworth et al., 2012). For instance, industrial, hospital, and sewage treatment effluents, as well as the septic tank are the main point sources for pharmaceuticals discharged to the water bodies.

Detailed explanation-2: -Pollution originating from a single, identifiable source, such as a discharge pipe from a factory or sewage plant, is called point-source pollution.

Detailed explanation-3: -A point source is a single, identifiable source of pollution, such as a pipe or a drain. Industrial wastes are commonly discharged to rivers and the sea in this way.

Detailed explanation-4: -Point-source pollution is easy to identify. As the name suggests, it comes from a single place. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once.
