| 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. |
