Serial_No:04172317:05 Project Name: Project Number: WEST ORANGE DPW Lab Number: L2317290 IN000380.09 Report Date: 04/17/23 Data Qualifiers ND - Not detected at the reporting limit (RL) for the sample. NJ - Presumptive evidence of compound. This represents an estimated concentration for Tentatively Identified Compounds (TICs), where the identification is based on a mass spectral library search. - The RPD between the results for the two columns exceeds the method-specified criteria. P Q R - The quality control sample exceeds the associated acceptance criteria. For DOD-related projects, LCS and/or Continuing Calibration Standard exceedences are also qualified on all associated sample results. Note: This flag is not applicable for matrix spike recoveries when the sample concentration is greater than 4x the spike added or for batch duplicate RPD when the sample concentrations are less than 5x the RL. (Metals only.) - Analytical results are from sample re-analysis. RE - Analytical results are from sample re-extraction. S - Analytical results are from modified screening analysis. V - The surrogate associated with this target analyte has a recovery outside the QC acceptance limits. (Applicable to MassDEP DW Compliance samples only.) - The batch matrix spike and/or duplicate associated with this target analyte has a recovery/RPD outside the QC acceptance limits. (Applicable to MassDEP DW Compliance samples only.) Z Report Format: Page 72 of 76 Data Usability Report
