Sediment was sampled at three stations in April 1990 near the Weyerhaeuser's pulp and paper mill waste treatment plant outfall. Sediments were sampled for dioxins, furans, volatile and semivolatile compounds, metals, organochlorine pesticides and PCBs. Sediment samples were taken near the point of effluent discharge, at a point 300 ft downstream from the discharge, and at a point 4500 ft upstream from the point of discharge. Conventional analyses included TOC and grain size.
The objectives of the Weyerhaeuser, Longview Pulp and Paper Mill's Class II Inspection were to verify effluent compliance with NPDES permit (NPDES Permit No. WA-000012-4), characterize priority and non-priority pollutants in industrial in-plant waters, treatment effluent and in sediments near the 001/002 outfall, determine the removal efficiency achieved with secondary treatment of industrial streams, evaluate any toxicity in the 001/002 effluent and sediments using several bioassays and to characterize any priority pollutants in the Radakovitch landfill leachate or in the R-W Paper plant drainage into Longview Ditch #3 (Andreasson 1991). The inspection also reviewed lab procedures at the mill to determine adherence to accepted protocols and advance state-of-the-art compliance inspections by contributing to ongoing developmental efforts with centrifugation.
The area of study was Lower Columbia River, Longview. The sampling locations were near the Weyerhaeuser's pulp and paper mill's waste treatment plant outfall. Samples were collected next to the 54" diffuser outfall pipe, approximately 300 ft downstream from the diffuser and approx
Individual sample grabs were placed on ice and delivered to the laboratory.
Target analytes included Dioxin/furans; volatile and semivolatile compounds; metals (Sb, As, Be, Cd, Cr, Cu, Pb, Hg, Ni, Se, Ag, Ti, and Zn); organochlorine pesticides and PCBs. Conventional analyses included TOC and grain size.
Analytical techniques included Dioxin/furans (EPA 8290); VOAs (EPA 8240), BNAs (EPA 8270), metals (EPA 7041, 7060, 6010, 7131, 7421, 7740, 7841), pesticides/PCBs (EPA 8080). All results, except for mercury, were reported on a dry weight basis. Mercury results were converted to dry weight basis for entry into the database using the reported percent solids content of the sediment. 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.

Data Presentation Form:
Laboratory procedures which were followed are described by Kirchmer (1988) and Huntamer and Smith (1988). Matrix spike, matrix spike duplicate, and internal standard recoveries were performed.
The laboratory data were reviewed and data qualifiers were added as appropriate. The data qualifiers used were defined as follows: B - Indicates method blank contamination; EMPC - Estimated maximum possible concentration; J - Estimated value when result in less than the specified quantitation limit; REJ - Rejected analytical result; U - Not detected. Value is the quantitation limit. All data entered in the database were reviewed for data entry errors.
