Cities and towns are characterized by vast expanses of impervious surfaces. This lack of infiltration opportunity results in water pollution as runoff carries pollutants into nearby water bodies. Runoff pollution from the town of South Hadley, MA threatens major water bodies including the Connecticut River. Non-point pollutant sources include automobiles, household chemical uses, pets, lawns, gardens, and business practices. Typically, storm water runoff from driveways and roads is not treated before flowing into the watershed. Nor is there an opportunity for natural treatment by infiltrating directly into soil layers due to the large quantities of impervious surfaces. Increasing infiltration opportunity is critical to reducing water pollution as storm water runoff transports a host of pollutants into water bodies.
