Water Pollution point Vs. Non-point

By: Christian Thomas

Pollution Point Sources:

These are a single most noticeable area where pollution is spotted. Mainly pipes or drains.

Pollution Non-point Sources:

Basically instead of a single point, it occurs in a wide area and not in one main place that can be determined.

Example of Point sources:

  • combined sewer outfalls.
  • discharges from wastewater
Each of these examples illustrates point source pollution. In each of the examples, the contaminant is introduced directly into the environment at a single location.

Example of Non-Point Sources:

  • Sediments from construction, agricultural lands.
  • Bacteria and microorganisms from failing septic systems and pet wastes.
  • Nutrients from pesticides from agricultural areas, golf courses, athletic fields and residential yards.
  • Litter: thrown onto streets, sidewalks and beaches, or directly into the water by individuals.
