Point sources — European Environment Agency
Point source pollution. Discharges from wastewater treatment plants and industry cause pollution by oxygen consuming substances, nutrients and hazardous substances. The adverse impacts depend very strongly upon the degree to which (if at all) such discharges are treated before reaching waterways.

Point Source Pollution,Point Source Water Pollution,Types
This kind of pollution is easy to manage as it can be traced to a single source like pipes, etc. Some factories and sewage treatment plants directly connect themselves to the water bodies and create point source pollution. Since, it comes from a single identifiable source, point source pollution is easier to control.

Point Source and Nonpoint Sources of Pollution | National
Municipal wastewater treatment plants are another common source of point-source pollution. Effluent from a treatment plant can introduce nutrients and harmful microbes into waterways. Nutrients can cause a rampant growth of algae in water. Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area.
