  "definition": "1. The minimum concentration that can be reported as a quantitated value for a target analyte in a sample following analysis. This defined concentration can be no lower than the concentration of the lowest calibration standard for that analyte, and can only be used if acceptable quality control criteria for the analyte at this concentration are met. {ORD} {OW/EAD} {OPP} {ORCR}\n\n2. The minimum concentration that can be reported as a quantitated value for a target analyte in a sample following analysis. This defined concentration can be no lower than the concentration of the lowest calibration standard for that analyte, and can only be used if acceptable quality control criteria for the analyte at this concentration are met. (ORD)\n\n3. Definition (from 40 CFR 141.40): The value and unit of measure at or above which the concentration of the contaminant must be measured using the approved analytical methods. The MRL is the minimum concentration of each analyte that must be reported to EPA. The MRL is an estimate of the quantitation limit. Assuming good instrumentation and experienced analysts, an MRL is achievable, with 95% confidence, by 75% of laboratories nationwide.",
