Old Mouth of the Cowlitz River Sediment Evaluation
Entry ID: BESTsed28


Summary
Abstract: The old mouth of the Cowlitz River provides a channel from deep water
in the Columbia River to old river mile 0.7 of the Cowlitz River. The
site has been dredged in the past to maintain the channel. The
objective of the study was to evaluate the sediments for chemical
contaminants and physical parameters which would prohibit unconfined
in-water disposal. Analytical testing for metals, polynuclear
aromatic hydrocarbons, phenols, pesticides, and PCBs were conducted on
four sediment samples collected in January 1991. Six samples were
analyzed for grain size and volatile solids.

The area of study was the Lower Columbia River - Old mouth of Cowlitz River.

Subsamples of sample cores were transferred to glass jars lined
with teflon lids. Samples were cold stored in an ice chest.

Target analytes were nine metals, polynuclear aromatic hydrocarbons,
phenols, organochlorine pesticides, PCBs, grain size, and volatile
solids. All data are reported on a dry weight basis.

Analytical techniques included the fact that samples were analyzed
following EPA methodology for all chemical analyses. U.S. Army Corps
of Engineers methodology was followed for physical parameters. All
results are reported on a dry weight basis.

The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.

Quality
Laboratory quality control consisted of method blanks, duplicate
analyses, matrix spikes, and surrogate spike recoveries. All QC data
were within acceptable limits with the exception of matrix spike
recoveries for three pesticides. The recoveries were outside of the
upper control limits; however, as these compounds were not detected in
the samples, it was determined that the data were not adversely
impacted by the high recoveries. The only qualifier code used in the
data set provided was "U" - Not detected. Value given is the detection
limit; Data presented for this report were from the laboratory data
sheets. Results were compared to CENPP Tiered Testing Guidelines and
requirements of Section 404 of the Clean Water Act for acceptability
for in-water disposal. All data entered in the database were reviewed
for data entry errors. All detected errors were corrected. Latitude
and longitude of sampling locations were not provided. Latitude and
longitude were estimated for entry along with the data provided in the
database.
