Sometimes “qualifiers” are applied to a sample result to note problems or irregularities that may have occurred during analysis. Most labs use a standard set of these .This fact sheet discusses the use of the U.S. Environmental Protection Agency’s (EPA) Contract Laboratory Program (CLP) data and other sources of data qualified with a “J”, “U”, or “UJ” .
Results reported with a “J” qualifier are below the reporting limit and above the laboratory method detection limit (MDL) and are used in the calculation as shown in the laboratory .A laboratory audit report, detailing significant findings and, possibly, suggestions to correct deficiencies. A follow up with the laboratory on its corrective action plan to addresses .limit (RL), qualify the result with an estimate or “J” flag. When reporting a non -detect result, qualification must include a comment noting that the target analytes were not identified . Appendix V lists the parameters and criteria that produce a "J" flag in accordance with the National Functional Guidelines for Organic Data Review (EPA 1991e) and Laboratory .

J: This flag indicates that the analyte was estimated in the analysis because it was between the RL and DL. The laboratory in August 2023 included additional J qualifiers. .USEPA risk assessment guidance documents indicate that J data may be used in risk assessments (USEPA, 1989; USEPA, 1992). The USEPA Risk Assessment Guidance for .
a test result is above the MRL, the laboratory has acknowledged that it is confident in the accuracy of this result. MRLs vary by laboratory. What does it mean when there is a J next to the result number? The report may include a “J” flag next to a test result. This means that the concentration is above the Method Detection Limit (MDL) butEnvironmental Protection Agency’s (EPA) Contract Laboratory Program (CLP) data and other sources of data qualified with a “J”, “U”, or “UJ” qualified or flag. This guidance provides a management decision tool for the optional use of qualified data to .A validator can also agree with an assigned laboratory flag and retain the laboratory flag as a final qualifier without modification. It is good practice to record laboratory flags and validation qualifiers separately so it is clear .
A.J.B.3.3 Are CRA and CRI standards within control limits: Metals 90 - 110? [__] V Is eid-range standard within control limits: Cyanide 85 - 115? fj£j __ __ ACTION': Flag the affected data within the range *(true value ^ CRDL) as estimated (J) if recovery is less than 901 (for CN <85Z); flag the positive data within the range (true value . Professionals trained in data validation procedures review this information, "flag" data with qualifiers when QA/QC criteria are not met, and prepare the data validation report. The documents presented are used to evaluate the quality of laboratory-generated analytical data. Evaluation of Laboratory Data Qualityquantitation (LOQ). Laboratory J flags were preserved in the data and included in the Data Qualification Summary table at the end of this report. Data were also qualified due to a method blank detection , a laboratory duplicate, and out of range holding times. Data qualifiers used during this validation included: J – Estimated concentrationThis value is considered an estimate (CLP E-flag). E-01: The concentration indicated for this analyte is an estimated value above the calibration range. F-01: The sample was received without proper field flocculation. Therefore, flocculation process was performed at the lab as soon as possible. FILT: The sample was filtered prior to analysis. FP
If correlation coefficients <0.995, then J and UJ flag positive and non-detect results. If %R <65, then J- flag positive results and R-flag non-detects If 65-90%R, then J- flag positive results and UJ flag non-detects If 110-135%R, then J flag positive results If >135%R, then J+ flag positive results If >170%R, then R flag positive results 18.The reported value is greater than or equal to the laboratory method detection limit but less than the laboratory practical quantitation limit. J Estimated value. A “J” – qualified sample value shall be accompanied by a detailed explanation to justify the reason(s) for designating the value as . sample >2 and was not adjusted by laboratory prior to analysis, J-flag positive results and R-flag non-detect results. 2. Were all COC records signed and integrity seals intact, . 0 If <50%R, J-flag positive results and R-flag non-detects 20. Was a LCS analyzed for each preparation batch (one per 20 samples per matrix and level)?

Laboratory J flags were preserved in the data and included in the Data Qualification Summary table. Data qualifiers used during this validation included:The Quality Control Section of ESS Laboratory's analytical report is located after the Sample Results. It is used to determine the data usability of the samples. The Method Blank is an analyte free matrix, (reagent water, clean sand, sodium sulfate), which is carried through the complete preparation and analytical procedure. The Method Blank is .2) Do not report any flags added by the contract lab, except for J or C. 3) QC flags that are indicated for the actual samples are not required for the PES results. 4) Since these data are for internal Quality Control, the PES results are removed from the production data packages and kept only in the SESD file copy.
