Lower Columbia and Willamette River Contaminant StudyEntry ID: BESTsed22
Abstract: The report is a compilation of contaminant data entered in the
U.S. Army Corps of Engineers, Portland District's Columbia River
sediment database as of May 1991 (Stockton 1991). The database is
separated into two sections containing estuarine and riverine data.
The riverine database includes data from the Willamette River up to
the Broadway Bridge area in Portland, as well as sampling stations as
... far upstream as Wind River. The estuarine database includes sampling
stations in the lower reaches of the Columbia River. Sampling sites
contained in the database are from Federal dredging projects. Data
are provided for grain size, total organic carbon, metals, pesticides,
total PCBs, and total PAHs. Samples include surface sediments and
sediments collected by coring, which may include sub-surface sediments.
The area of study was the Lower Columbia River, Willamette River.
Target analytes were Grain size, total organic carbon, ten metals,
pesticides, total PCBs, total PAHs, oil and grease, and ammonia.
All results are reported on a dry weight basis.
The report is a printed copy of the Army Corps of Engineers' Columbia
River sediment database as of May 1991. Information regarding
analytical techniques was not available. No information was provided
on the method used to determine the total concentrations of DDT, DDE,
DDT, PAHs, or PCBs.
The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.

Quality Information relevant to quality assurance/quality control was not
available. However, the U.S. Army Corps of Engineers has a Quality
Assurance/Quality Control program for review and evaluation of
contaminant data. Information regarding the quality of specific data
may be obtained by contacting the Portland District Corps of
... Engineers. 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 cautioned that not all of the database entries are for
surface sediments. Some analyses were conducted on sediments
collected with coring devices. Therefore, some samples include
sub-surface sediments collected from a few to several feet below the
sediment surface. All data entered in the database were reviewed for
data entry errors. All detected errors were corrected.
