PCDDs/PCDFs in Columbia River Suspended Particulate Matter.Entry ID: BESTsed14
Abstract: The Department of Ecology (WDOE) conducted a sampling of suspended
particulate matter (SPM) from the Columbia River at Northport as part
of an investigation into the impact on Lake Roosevelt of discharges
from the Celgar bleached kraft pulp mill in Castlegar, B.C (Johnson et
al. 1991). The objectives of this study were to make the first
determination of PCDD/PCDF concentrations in Columbia River ... water,
obtain a preliminary estimate of loads to Lake Roosevelt and provide
data to the Water Quality Program and EPA to assist in refinement of
the Columbia River total maximum daily load for 2,3,7,8-TCDD. The
field work was conducted with an extensive Environment Canada study of
water quality in the border reach of the Columbia River which included
SPM samples for PCDDs/PCDFs.
The area of study was Columbia River-U.S./Canadian border with
sampling done in Northport.
The centrifuges were operated simultaneously over a period of
approximately 57 hours starting at 2315 hour on October 9 and ending
at 0836 on October 12th. Flow rate was 1.2 gallons/minute with a
total of 4.082 gallons of water passing through the centrifuge.
Target analytes included 17 congeners of dioxins and furans.
Analytical techniques included Dioxins and furans (EPA Method 8290).
Data are reported in dry weight. 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 QA measures included matrix spikes and centrifuge blanks.
The laboratory data were reviewed and data qualifiers were added as
appropriate. However, the only data qualifier that could be defined
was "U" - Not detected. The "B" qualifier indicated that the analyte
was also ... detected in the laboratory blank sample. Value is the
detection limit. The qualifier code "F" was not defined. Analyses
with these qualifier codes were reported by Alta Laboratory.
Users of these data should be aware that they are from only one
All data entered in the database were reviewed for data entry errors.
All detected errors were corrected.
