THRU: Dr. William J. Andrade, Chief, Chemistry Section
TO: Dorothy Girten l\7 7 ' i l l ^O Superfund Records Center SITE: fay^a^ BREAK: a-3 OTHER: PROJECT NUMBER: 92026
ANALYTICAL PROCEDURE:
All samples were received and logged in by the laboratory according to the chain of custody SOP (G-2, 11/88, DCN: CH001/88).
EPA Region 1 Procedure for Medium Level Analyses for Extractable Organics in Solid Matrix Samples. The samples are extracted by the medium method of RCRA 3550 using methylene chloride and acetone. The extracts are analyzed on a gas chromatograph/mass spectrometer. All the values are reported out on a dry weight basis.
Date(s) Samples Received by the Laboratory: 11/18/91
Date Analysis Started: 11/22/91

QUALITY CONTROL:
1. A laboratory blank was analyzed before the sample analysis.
2. Each sample was spiked with several surrogate compounds at approximately 75 mg/kg concentration. The results for the surrogate recoveries are reported out for each sample.
3. One sample, 00550, was spiked as a matrix spike with the following compounds at approximately 75 mg/kg concentration.
