| Description | The lower Yakima River and the mainstem Granger Drain have not met the Class A fecal coliform (FC) water quality standard of the State of Washington (State) for over three decades of monitoring. The Washington State Department of Ecology (Ecology) and other agencies have historically attributed the excessive FC contamination to the numerous animal feeding operations (AFOs) within the watershed. However, there are present other potential sources of FC pollution such as: “hobby farms”, septic tanks, wildlife and urban runoff. FC pollution is extremely seasonal throughout the watershed with the greatest bacterial densities always occurring during the irrigation season of the local agriculture. | ||||||
