Short Description

This detailed implementation plan (DIP) provides direction to assure that arsenic concentrations in the Similkameen River continue to decline, and to insure that increases in arsenic concentrations are addressed appropriately. The Washington State Department of Ecology (Ecology) began an assessment of the 1996 and 1998 303(d) listings for arsenic contamination in Washington′s portion of the Similkameen Watershed. The purpose of the investigation was to determine the sources and quantity of arsenic in the river and provide direction to address the impairment of water quality.
