Beyond what we can do individually, local, regional and state governments can also help reduce nonpoint source pollution by enacting and enforcing building codes and other rules that can reduce outflows. The voluntary reduction in phosphates in dishwashing detergents in the U.S. last year, for example, was a big step in reducing the nutrient load into our streams and lakes. Some municipalities have gone so far as to mandate erosion and sediment control ordinances requiring the construction of natural buffers in building and landscaping projects to filter out pollutants before they reach local watersheds. If your community doesn’t have similar rules in place, encourage your local officials to enact them. CONTACT: EPA’s Nonpoint Source Pollution Page, www.epa.gov/owow_keep/NPS.
