Common Pollutants from Non-Point Sources:
Sources of Water Pollution
Water pollution comes from many different sources. Point Sources, like the effluent from wastewater treatment plants, are easier to identify. Although there are occasional exceptions, our water treatment plants, have implemented technology over the past few decades to remove bacteria to near zero detection during summer months. However, more can be done at by controlling bacteria levels in plant effluent year-round rather than just during April through October. More recently, the State has been working with municipalities to also reduce nutrient levels of nitrogen and phosphorus in their effluent discharge.
Non-Point Sources are more challenging to identify. Unlike sewage or industrial treatment plants, they are more diffuse coming from the everyday activities of many different people. The impact of pollution from non-point sources is compounded by urbanization which has contributed to the explosive increase of impervious surfaces like buildings, pavement and compacted landscapes, making it easier for stormwater to carry a variety of pollutants to our waterways.
Like the ones listed on the left.
These pollutants can kill native vegetation, harm fish and other wildlife. They can make are recreational areas unpleasant and unsafe for our families and our pets. And the potential to foul our drinking water is real.
