Abstract
Sample concentration was less than or equal to the upper tolerance level (UTh) calculated for the blanks for that analyte in that media. These data are considered indistinguishable from blank concentrations. Analyte exceeded calibration range, but did not saturate the detector, therefore data is usable. Co-elution or interference was suspected in the determination of the concentration of the flagged compound. These data may be biased high due to interference, although the QAIQC data for the sample were within acceptance criteria. These data are considered conservative (biased high) concentrations and are used in the risk assessment. Result is less than sample specific detection limit. Data with this flag should be interpreted with caution. The presence of the analyte was not confirmed because the compound was not detected on both the primary and secondary columns. Only 'KJ' flagged data are reported and are intended for use as proxy values for risk assessment. This flag is used on methods requiring second column confirmation (SW8OlO, SW8015, SW8Ol5MP, SW8020, and SWSO8O).
