I Q05 Chemistry Validation Comments-- 04/05/05 <br /> Site No 5469 Lab No M-030479 Classification Groundwater Monitoring <br /> Data Acceptable with Issues <br /> • The reported results for GRO in samples MW-3, MW-4,MW-5,MW-6, and MW-8 are due to a discrete <br /> peak in the quantitation range(probably MtBE) <br /> • The reported results for Ethanol in samples MW-3 should be considered possibly biased low because the <br /> associated continuing calibration standard was outside of acceptance criteria <br /> • The reported results for 1,2-DCA in samples MW-7 may be biased high because the associated continuing <br /> calibration standard was outside of acceptance criteria <br /> • The reported results for the plate count analysis in samples MW-1, MW-4, MW-5,MW-6, MW-7,MW-8, <br /> MW-9 and MW-10 may be estimated since the analyses for these analytes were performed beyond the U S <br /> EPA recommended holding time <br /> • The elevated reporting limits were the result of dilutions performed by the laboratory in order to quantitate <br /> a target analyte <br /> No Further Comments <br /> The data validation report will be included in the e-mail <br />
