Description Sediment from Dillenbaugh Creek, near Chehalis, Washington, was analyzed for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDFs). PCDD/PCDF contamination was found in a half-mile segment of the creek downstream of a former wood-treating facility stormwater lagoon. Although Washington State does not have a numerical freshwater sediment quality limit for PCDD/PCDF, some concentrations were over 100 times the dioxin soil cleanup level.

Upstream of the stormwater lagoon, PCDD/PCDF concentrations were less elevated, suggesting that the contamination may have entered the creek from the lagoon. At some upstream locations, PCDD/PCDF concentrations were still above the dioxin soil cleanup level.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
