Practical Quantitation Limit (PQL) definition
Practical Quantitation Limit (PQL) means the minimum concentration of an analyte (substance) that can be measured with a high degree of confidence that the analyte is present at or above that concentration. The use of PQL in this document may refer to those PQLs shown in Part I.D of this permit or the PQLs of an individual laboratory.
Practical Quantitation Limit (PQL) means the lowest constituent concentration at which a numerical concentration can be assigned with reasonable certainty that its value represents the constituent’s actual concentration in the sample. Normally PQLs should be set equal to the concentration of the lowest standard used to calibrate the analytical procedure. The PQL shall reflect the quantitation capabilities of the specific analytical procedure and equipment used by the laboratory. PQLs reported by the laboratory shall not simply be restated from U.S. EPA analytical method manuals. In relatively interference-free water, laboratory-derived PQLs are expected to closely agree with published
Practical Quantitation Limit (PQL) means the lowest concentration of an analyte that can be measured within specified limits of precision and accuracy during routine laboratory operating conditions.
Examples of Practical Quantitation Limit (PQL) in a sentence
PQL The Practical Quantitation Limit (PQL) is defined as the lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions.
If the concentration for a contaminant is below the Practical Quantitation Limit (PQL), generally as published in Test Methods for Evaluating Solid Waste, USEPA SW-846, revised December 1987, the PQL may be considered as the remediation level.
Supporting Definitions listed below PQL The Practical Quantitation Limit (PQL) is defined as the lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions.
ITB Paragraph 3.5) Upon request from the County, the laboratory shall provide a written fee proposal for sample collection and/or sample analyses not listed in Bid Proposal Forms and/or for analyses listed in Bid Proposal Forms for which a different method, media, Method Detection Limit (MDL) or Practical Quantitation Limit (PQL) is required.

Practical Quantitation Limit (PQL) means the minimum concentration of an analyte (substance) that can be measured with a high degree of confidence that the analyte is present at or above that concentration.
Practical Quantitation Limit (PQL) means the value established as a target value by USEPA that is the lowest concentration of a substance that can be consistently determined within +/- 20% of the true concentration by 75% of the laboratories tested in a performance evaluation study. Alternatively, if performance data are not available, the PQL for carcinogens is the method detection limit (MDL) multiplied by 5, and for noncarcinogens is the MDL x 10. These estimated PQLs are listed in Appendix II to 40CFR258. Generally, these are target values that may not reflect the constraints of matrix effects; therefore, the RWQCB requires the discharger to keep an up-to-date listing of the applicable laboratory-specific PQL and MDL estimates for each analyte on the constituent of concern list.

Practical Quantitation Limit (PQL) means the lowest concentration that can be reliably measured within specified limits of precision and accuracy for a specific laboratory analytical method during routine laboratory operating conditions in accordance with “Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods,” EPA Publication No. SW-846, incorporated by reference in Section 1100.104 of this Part.
Practical Quantitation Limit (PQL) means the value established as a target value by the United States Environmental Protection Agency that is the lowest concentration of a substance that can be consistently determined within +/- 20% of the true concentration by 75% of the laboratories tested in a performance evaluation study. Alternatively, if performance data are not available, the Practical Quantitation Limit for carcinogens is the Method Detection Limit multiplied by 5, and for noncarcinogens is the Method Detection Limit multiplied by 10. These estimated Practical Quantitation Limits are listed in Appendix II to Title 40 of the Code of Federal Regulations Part 258. Generally, these are target values that may not reflect the constraints of matrix effects; therefore, the Regional Water Quality Control Board requires the discharger to keep an up-to-date listing of the applicable laboratory-specific Practical Quantitation Limit and Method Detection Limit estimates for each analyte on the Constituent of Concern list.
