| Description | This study researched and documented nonpoint source pollution in Washington State, including the linkage between land uses, human activities, and nonpoint pollution. The study evaluated information produced since 2005, including: • U.S. Environmental Protection Agency guidance • Recent research • Nonpoint pollution reduction targets in Total Maximum Daily Load studies • Section 319 grants • Case studies from the Walla Walla, Lower Yakima, Dungeness, and Samish Basins. The study describes the impacts of different nonpoint pollution sources, including: agriculture; urban and residential areas; hydromodification; marinas and boating; forests; atmospheric deposition; and natural sources. Results show that nonpoint pollution from these sources is widespread in Washington and causes a variety of water pollution problems. Best management practices can help reduce pollution impacts. Spreadsheet files for Appendices A and C are linked to the report above as zip files. |
