| Description | Toxaphene is a chlorinated pesticide that was used historically in the Walla Walla basin on alfalfa crops. The purpose of this 2014 study was to identify the sources of toxaphene within the Pine Creek watershed of the Walla Walla River basin. An overflow ditch from an irrigation canal that drains into Pine Creek is a source of toxaphene during the spring freshet/irrigation season and the fall/winter irrigation season. Sediment and upland soil samples confirm the presence of toxaphene in areas that are easily eroded by wind and runoff into the overflow ditch. The analytical chromatography of toxaphene in different media from different sites suggests that the same degraded toxaphene is being transported throughout the watershed. | ||||
