FLAGS/NOTES AND DEFINITIONS PQL B I J K L M N O Q T U V Y Z PQL: Practical Quantitation Limit. Results are based upon membrane filter colony counts that are outside the method indicated ideal range. The reported value is between the laboratory method detection limit (MDL) and the practical quantitation limit (PQL). Estimated value. The associated sample note or project narrative indicate the causative reason. Off-scale low; Actual value is known to be less than the value given. Off-scale high; Actual value is known to be greater than value given. Presence of analyte is verified but not quantified; the actual value is less than the MRL but greater than the MDL. Presumptive evidence of presence of material. Sampled, but analysis lost or not performed. Sample exceeded the accepted holding time. Value reported is less than the laboratory method detection limit. The value is reported for informational purposes only and shall not be used in statistical analysis. Indicates that the compound was analyzed for but not detected. Indicates that the analyte was detected in both the sample and the associated method blank. The laboratory analysis was from an improperly preserved sample. The data may not be accurate. Too many colonies were present (TNTC); the numeric value represents the filtration volume.? Data are rejected and should not be used. Some or all of the quality control data for the analyte were outside criteria, and the presence or absence of the analyte cannot be determined from the data. * Not reported due to interference. O-04 This sample was analyzed outside the EPA recommended holding time. QM-02 QM-07 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration of analyte inherent in the sample. The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. Page 20 of 21
