Lower Columbia and Willamette River Contaminant Study
Listed in NASA Earthdata CMR
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).
Description
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.
