Study Notes
Sources of Water Pollution
- The four main sources of contaminants that result in water pollution are industrial waste, agricultural runoff, sewage, and oil spills.
Toxic Substances
- Examples of toxic substances mentioned as contributors to water pollution include pesticides, herbicides, and industrial chemicals.
Forms of Water Pollution
- The two forms of water pollution mentioned in the text are point-source and non-point-source pollution.
Point-Source Pollution
- Point sources of water pollution are single, identified sources of contaminants, such as factories, sewage treatment plants, and oil tankers.
Non-Point-Source Pollution
- Non-point sources of water pollution are diffuse, scattered sources of contaminants, such as agricultural runoff, urban stormwater, and atmospheric deposition.
Cumulative Effect of Pollution
- The result of the cumulative effect of pollution over time is the degradation of water quality and ecosystems.
