Storm water is water from rain and snowmelt. As rain and snow falls to the earth in agricultural and undeveloped areas, it is absorbed by the soil. The storm water in urban developed areas is less permeable because of impervious surfaces such as rooftops of homes and businesses and paved areas which create a much faster rate of run off. The problem develops when this run off is not detained and conveyed into the City’s storm water collection system, then into a river or tributary. Untreated runoff carries pollutants from our daily activities such as gasoline, oils, heavy metals, pop bottles, Styrofoam cups, and paper trash. Pesticides, herbicides and fertilizers that are washed from our lawns and other green spaces are contained in this run off.
