Lower Columbia River Contaminants Study
Listed in NASA Earthdata CMR
These data represent the USACOE, Portland District's sediment quality data with regard to dioxins and furans in sediment samples from areas that have already been dredged and areas that may potentially be dredged (Siipola 1994).
Description
Sample locations include areas where there is potential dioxin and furan sediment contamination and/or where previous sampling has indicated the presence of similar hydrophobic organic compounds (PCBs, PAHs, pesticides) or dioxin/furans.
PAHs, PCBs, pesticides and metal analysis results are reported in Stockton (1992). The area of study was Lower Columbia River. Target analytes were Dioxins and furans; PAHs; PCBs; metals.

Analytical techniques included : Dioxins and furans (EPA Method 8290). All results are reported on a dry weight basis. Total dioxin and furan concentrations were determined by the laboratory as the sum of the individual congeners that were detected.
The information for this metadata was taken from the Columbia River Basin: Sediment Database Abstracts.
