Non-point Source Pollution
During a precipitation event, sediments, chemicals, and litter are conveyed through the storm drain system and are discharged into our waterways. These materials constitute non-point source pollution, or pollution that does not originate from any single source, like an industrial or sewage treatment plant. The materials are thus discharged into water bodies untreated.
The effects of non-point source pollution vary and may have harmful effects on our drinking water, our environment, and the wildlife that are not fully assessed. Organic pollutants discharged in great quantities can overwhelm the ecosystem, causing algal blooms, changes in oxygen levels, and other harmful effects. Some chemical pollutants are toxic and can greatly impact an entire ecosystem, even when present in small concentrations.
