Storm Water run-off remains the nation’s largest water quality problem. Nearly 40% of surveyed U.S. water bodies do not meet water quality standards. As stormwater moves across the land, it picks up and carries away natural and human-made pollutants, depositing them into lakes, rivers, and wetlands. The source of water pollution results from a variety of human activities on the land. Each of us can contribute to the problem without even realizing it. The City of El Mirage is a participant in the federally mandated National Pollutant Discharge Elimination System (NPDES) Phase II under the Clean Water Act. EPA issued a final Phase II regulation on December 8, 1999.
