| Abstract | Long Description |
The Touchet River has been listed by Washington State under Section 303(d) of the federal Clean Water Act for non-attainment of Washington State fecal coliform bacteria and pH criteria. The U.S. Environmental Protection Agency requires the states to set priorities for cleaning up 303(d) listed waters and to establish a Total Maximum Daily Load (TMDL) water cleanup plan for each. The Touchet River was included in the Walla Walla River TMDL that was conducted in 2002. As a result, additional monitoring for the Touchet River has been recommended (Joy and Swanson, 2005; Joy et al, 2007). This Supplemental Quality Assurance Project Plan describes additional monitoring that will address: --Possible inconsistencies in the effectiveness of the Dayton Wastewater Treatment Plant ultraviolet (UV) disinfection levels. --Possible groundwater nutrient transport from the wastewater lagoon at the Waitsburg Wastewater Treatment Plant to the Touchet River. --Validation of nutrient levels in the Touchet River upstream and through the city of Dayton. The study will be conducted by the Washington State Department of Ecology′s Environmental Assessment Program. |
