Reconaissance Survey of the lower Columbia RiverEntry ID: BESTsed26
Abstract: Tetra Tech, Inc., was contracted by the Lower Columbia River Bi-State
Program to conduct a reconnaissance level survey of water, sediment,
and biota (fish and crayfish) contaminant levels in these media of the
lower Columbia River below Bonneville Dam (Tetra Tech 1993). Sediment
and fish tissue sampling (including crayfish) focused on locations in
the mainstem and backwater areas of the lower ... river. Sediment
sampling was conducted using a stainless steel 0.1 m2 van Veen grab
deployed by winch from a vessel. Station latitude and longitude were
recorded from geographic coordinates provided by a Magnavox MX 2000
Global Positioning System (GPS) Navigator System receiver onboard the
vessel. The GPS locational information was not corrected for the
U.S. Department of Defense's Selective Availability, and therefore the
GPS latitudes and longitudes provided are accurate to approximately
The area of study was the Lower Columbia River - Bonneville Dam to
Sediment samples consisted of a homogenized composite of at least 3
grab samples. Samples were shipped on ice to laboratory. Sample
chain-of-custody procedures were followed.
Target analytes were seventeen dioxin and furan congeners, 7 PCB
Aroclors, 16 metals and trace elements (Al, Sb, As, Ba, Be, Cd, Cr,
Cu, Fe, Pb, Hg, Ni, Se, Ag, Tl, Zn), cyanide, 52 semi-volatile organic
compounds (SVOCs) including 11 phenolic compounds and 15 polynuclear
aromatic hydrocarbons, 28 pesticides, 7 PCB Aroclors, 3 butyltin
compounds including tributyltin, and 7 long-lived radionuclides.
Conventional analyses included sediment grain size and total organic
carbon content. All data are reported on a dry weight basis.
Analytical techniques included Dioxins and furans (EPA Method 1613
with modifications); PCB Aroclors (EPA Method 8080); metals and trace
elements [Ag, Al, Ba, Cu, Cr, Fe, Ni, Sb, Tl, and Zn by ICP (EPA
Method 200.7); As (EPA 7060), Be (EPA 7091), Cd (EPA 7131), Pb (EPA
7421), and Se (EPA 7740) by GFAA; Hg (EPA 7471) by CVAA)]; cyanide
[colorimetry (EPA 9010)]; SVOCs (EPA 8270); pesticides and PCBs (EPA
8080), Butyltins (GC/MS with SIM); radionuclides by alpha spectroscopy
and gamma counting.
The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.

Quality The sediment data submitted by the laboratories were reviewed and
validated by Tetra Tech using guidance provided in the Quality
Assurance/Quality Control (QA/QC) Plan developed for this project and
guidance provided by U.S. EPA (1988a,b). A data validation report was
prepared as part of the final ... report and is bound separately as Volume
2: Appendix A, Data Validation Reports. The QA/QC procedures included
sampling and analysis of field and laboratory replicates and matrix
spike/matrix spike duplicate (MS/MSD) analyses on a minimum of 5
percent of the samples that were collected. Some data were qualified
based on review of laboratory replicate and MS/MSD results, and
additional instrument calibration and performance data provided by the
laboratories. The laboratory data were reviewed and data qualifiers
were added as appropriate. The data qualifiers used were defined as
follows: * For dioxin and furan results "*" indicates the analyte was
quantified using a DB-225 column. For pesticide/PCB results "*"
indicates that reporting limits were adjusted due to coeluting peaks.
For semivolatile compounds "*" indicates that the results presented
are from re-extraction and re-analysis of the sample; E-Estimated
value; J-Estimated value is less than the specified detection
limit;E/J-For butyltin data the estimated value is less than the
specified detection limit; E/M-For butyltin data low spectral match
pairs may affect the estimated value; M-Estimated maximum possible
concentration;R-Data unusable;U-Not detected. Value is the detection
limit. Although comparison between sediment and fish tissue
contaminant data collected in this program is possible, the sampling
area for fish at a particular station was generally greater than the
area designated as the sediment sampling station. Furthermore, with
the exception of crayfish, it is not known to what extent the fish
species collected reside in the vicinity of the sampling station. The
original data may be found in Volume 3: Data Tables. Appendices B, C,
D, &E. of Tetra Tech (1993). All data entered in the database were
reviewed for data entry errors. All detected errors were corrected.
