r' <br />i <br />ProVera__` <br />Analytical Laboratories, Inc. <br />Data Qualifiers & Definitions <br />Al - More than one compound of similar molecule structure was identified with equal probability <br />ca - The calibration results for this range fell outside of acceptance criteria. <br />c - The presence of the analyte Indicated may be due to carryover from previous sample injections. <br />d - The sample was diluted. Detection limits may be raised due to dilution, <br />ds - The sample was diluted. Detection limits are raised due to dilution and surrogate recoveries may <br />not be meaningful <br />dv - insufficient sample was available to achieve normal reporting limits and limits are raised <br />accordingly. <br />fb - The analyte indicated was found in the method blank. The result should be considered an estimate. <br />fc - The compound is a common laboratory and field contaminant. <br />ht - The samples was extracted outside of holding time. Results should be considered estimates. <br />ip -. Recovery fell outside of normal control limits. Compounds in the sample matrix interfered with the <br />quantitation of the analyte. <br />j The result is below normal reporting limits. The value reported is an estimate. <br />J - The internal standard associated with the analyte is out of control limits. The reported concentration is <br />an estimate. <br />jl - The analyte result in the laboratory control sample is out of control limits. The reported <br />concentration should be considered an estimate. <br />js - The surrogate associated with the analyte is out of control.limits. The reported concentration should <br />be considered and estimate. <br />Ic - The presence of the compound indicated is likely due to laboratory contamination. <br />L - the reported concentration was generated from a library search. <br />pc - The samples was received in a container not approved by the method. The value reported should be <br />considered and estimate. <br />pr - The sample was received with incorrect preservation. The value reported shouid be considered an <br />estimate. <br />df -The value reported fell outside the control limits established for this analyte. <br />x - The pattern of peaks present is not indicative of gasoline <br />y - The pattern of peaks present is not indicative of diesel. <br />*TPHg result does not include MTBE or TBA <br />5221 Woodmere Drive, Bakersfield, CA 93313 <br />Phone: (661) 827-5240 Fax: (681)87-5244 <br />
