WJ)t I 0/J ftlDorothy Girten

PROJECT NUMBER: 910256

ANALYTICAL PROCEDURE:

EPA Region 1 P~ocedure for the Medium Level Analyses for the Polychlorinated Biphenyls (PCBs) in Soil Samples. The samples were extracted by the RCRA Method 3550, Medium-high Concentra·tion, clean-up methods were RCRA Method 3665, Sulfuric Acid, and RCRA Method 3620B, Florisil cartridge, and the analysisby RCRA Method 8081, capillary column GC technique. The analysis was carried out using high resolution capillary chromatography.The 30-m dual capillary system consists of a J&W DB - 1701 and DB-5, both with a 0.25mm ID and a 0.25 micron film thickness. Results are reported out in dry weight. __

Date Samples Received by the Laboratory: 9/23/91

Date Samples Analyzed: 9/30-10/2/91

QUALITY CONTROL:

1. One method blank was included in the analysis.

2. Each sample was spiked with a surrogate compound,decachlorobiphenyl, approximately at 5 mg/kg. The results for the surrogate recoveries are reported out with each sample.

3. one sample, 00555, was spiked with Aroclor-1260 at approximately 3 mg/kg. Since the sample contains a high concentration of Arochlor-1260, the matrix was reported as a duplicate.
