Reported value is estimated. <br /> u=The result was reported with a possible high bias due m the continuing calibration verification falling outside the acceptance criteria. <br /> z=Due to low levels of analyte found in the sample,the analyte was qualitatively identified based on the compound's retention time and the presence of a single mass ion. <br /> bb=Extractable hydrocarbons analyzed with Silica Gel cleanup <br /> ee=Analyzed by EPA Method 8015B(M). <br /> If=Analyte was present in the associated method blank. <br /> hh=The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons are also present(or were detected) <br /> if=Sample container contained headspace <br /> Wells MW-13,MW-29,and MW-30 surveyed by PIS Surveys,Inc.
