According to the United States and California Environmental Protection Agencies, stormwater and urban runoff are the most significant remaining sources of receiving water contamination and benefical use impairments within United States waters. Recent advances in stormwater and urban runoff management have eliminated past impairments, improved the health of regional receiving waters, preserved natural resources, and conserved surface and groundwater resources.
