| Description | This report documents the findings of the additional monitoring for fecal coliform bacteria, pH, and dissolved oxygen on the Touchet River, recommended in the 2002 Walla Walla River TMDLs. The Department of Ecology (Ecology) monitored the effectiveness of ultraviolet disinfection on fecal coliform at the Dayton Wastewater Treatment Plant (WWTP) from May to October 2009. Ecology conducted two synoptic surveys (July and August 2009) to verify nutrient levels in the Touchet River. The Dayton WWTP discharged large nutrient loads to the Touchet River which appear to be contributing to eutrophic conditions in the river. The Waitsburg WWTP nutrient loads appear to encourage eutrophic conditions downstream. |
