Many do not consider impacts that pollutants generated from everyday life could have on our local water resources. Toxic chemicals from automobiles can lead to an increase in heavy metals and oils and greases, careless application of fertilizers can contribute to algal blooms severely degrading healthy aquatic environments, improper disposal of yard or pet wastes could make nearby water bodies unsuitable for wading, swimming or fishing, and poorly managed construction sites have been blamed for erosion and sediment migration, property damage, and destruction of local habitat. Pollution is any toxic discharge that enters into the stormwater sewer system, as stormwater flows (or snow melts), it picks up debris, chemicals - such as fertilizers and pesticides - dirt, cigarette butts and other pollutants. This discharge enters a storm sewer system and is discharged to a lake, stream, river, wetland, or coastal water. The City continues to make water infrastructure improvements and implements best practices to minimize pollutants from entering the water sewer system.
