Montgomery.Alabama 36116 205371.1444 EID939358 ORGANIC DATA QUALIFIERS U - indicates the compound was analyzed for but not detected. _ The number adjacent to the "O" qualifier indicates the reporting limit for that compound. The reporting limit can vary from sample to sample depending on dilution factors or percent moisture adjustment when indicated. J Indicates an estimated value. It is used when the data indicates the presence of a compound helow the stated reporting limit. C This flag applies to GC pesticide results only- The "C" flag xndiea the presence of this compound-has been confirmed by GC/MS analysis. (This definition is still being reviewed and discussed). B __ This flag is used when the analyte is found in the associated blank as weXl as the sample. This notation indicates possible blank contamination and suggests the data user evaluate these compounds and their amounts carefully* . E -- This qualifier indicates that the value reported exceeds the linear calibration range for that compound. Therefore, the sample should e reanalyzed at an appropriate dilution. The "E" qualified amount is an estimated concentration, and the results of the dilution will be reported on a separate Form I. D __ This qualifier indicates compounds which have been identified during a diluted reanalysis. "D" qualifiers are used for samples that have been analyzed initially at a lesser dilution than required for accurate - quantitation. * __ThiB qualifier indicates that the response for the compound exceeded the linear range of the instrument. Therefore, this is an estimated concentration. V-- This qualifier is used for a pesticide/Aroclor target analyte when there is greater than 25% difference for detected concentrations between the two GC columns. The lower of the two values is reported on Form I and flagged with a "P". N __This qualifier indicates presumptive evidence of a compound. This flag is only used for tentatively identified compounds, where the . identification is based on a mass spectral library search. It is appi fcrt to n TIC results. For generic characterization of a TIC, such as chlorinated hydrocarbon, the "H" qualifier is not used. A -- This qualifier indicates that a TIC is a Buspected aldol-condensation product. .

Smaller aliquots were used for the re-extractions to provide more insurance that surrogates would not be diluted out. III. ANALYSIS ' Ho other exceptions were encountered. A. Holding times: All holding times were met. Analytical Exceptions Several samples were diluted to prevent FC-143 from exceeding the calibration range. Both the original and the re-extractiona are reported since the re work was performed beyond the extraction holding time. ' Ho other exceptions were encountered. IV QUALITY CONTROL A. Method Blank B. Surrogate Recoveries FC--143 was not present in any of the laboratory blanks. All samples were re--extracted and reanalyzed as a corrective action for poor spike recoveries observed in the original work. C. Matrix Spike Results AT t re--extracted samples met acceptable.QC limits. Matrix spike results have been reported with this contract along with the laboratory control sample (blank spike) results. The analytical system was not in control for original extractions performed on 05/24/93. Spike recoveries were back to normal for the re-extractions performed on 06/01/93. I certify that this data package is in compliance with the terms and of the contract, both technically and for completeness, for other than the conditions detailed above.

The number adjacent to the "0" qualifier indicates the reporting limit for that compound. The reporting limit can vary from sample to sample depending on dilution factors or percent moiBture adjustment when indicated. J -- Indicates an estimated value. It is used when the data indicates the presence of a compound below the stated reporting limit. c __This flag applies to GC pesticide results only- The "C" flag indicates the presence of this compound-has been confirmed by GC/MS analysis. (This definition is still being reviewed and discussed). B -- This flag is used when the analyte is found in the associated blank as well as the sample. This notation indicates possible blank contamination and suggests the data user evaluate these compounds and their amounts carefully. . B -- This qualifier indicates that the value reported exceeds the linear calibration range for that compound. Therefore, the sample should be reanalyzed at an appropriate dilution. The "B" qualified amount is an estimated concentration, and the results of the dilution will be reported on a separate Form I D __ This qualifier indicates compounds which have been identified during a diluted reanalysis. "D" qualifiers are used for samples that have been analyzed initially at a lesser dilution than required for accurate - quantitation. . * __ This qualifier indicates that the response for the compound exceeded the linear range of the instrument. Therefore, this is an estimated concentration. P __This qualifier is used for a pesticide/Aroclor target analyte when there is greater than 25% difference for detected concentrations between the two GC columns. The lower of the two values is reported on Form I and flagged with a "P " . H __This qualifier indicates presumptive evidence of a compound. This flag is only used for tentatively identified compounds, where the . identification is based on a masB spectral library search. It is applied to all TIC results. For generic characterization of a TIC, such as chlorinated hydrocarbon, the "H" qualifier is not used. A -- qualifier indicates that a TIC is a suspected aldol-condensation product. .

Extraction Exceptions : All field samples were re-extracted to investigate low spike recoveries in the original extractions.' Smaller aliquots were used for the re-extractions to provide more insurance that surrogates would not be diluted out. . 1X1. ANALYSIS No other exceptions were encountered. A. Holding timess All holding times were met. B. Analytical Exceptions . t Several samples were diluted to prevent FC-143 from exceeding the calibration range. Both the original and the re-extractionB are reported since the re work was performed beyond the extraction holding time. ` No other exceptions were encountered. XV. QUALITY CONTROL A. Method Blank ; FC-143 was not present in any of the laboratory ' blanks. B. Surrogate Recoveries : All Bamples were re-extracted and reanalyzed as a corrective action for poor spike recoveries observed in the original work. C. Matrix Spike Results All re--extracted samples met acceptable .QC limits. Matrix spike results have been reported with this contract along with the laboratory control sample (blank Bpike) results. The analytical system was not in control for original extractions performed on 05/24/93. Spike recoveries were back to normal for the re--extractions performed on 06/01/93.
