Lower Columbia River Contaminants StudyEntry ID: BESTsed23
Abstract: 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). 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
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.

Quality Laboratory method blanks and internal standards were prepared and
processed along with each extraction batch as part of the quality
assurance/quality control procedure. The only qualifier code used in
the data set provided was "U" - Not detected. Value given is the
detection limit. Users of these data should be reminded that targeted
sample areas consisted of areas where dioxins and furans were expected
to be present. All data entered in the database were reviewed for
data entry errors. All detected errors were corrected.
