Abstract

QC sample results are required in order to have confidence in the results from analytical tests. Some of the AOAC water methods include specific QC procedures, frequencies, and acceptance criteria. These are considered to be the minimum controls needed to perform the method successfully. Some regulatory programs, such as those in 40 CFR Part 136.7, require additional QC or have alternative acceptance limits. Essential QC measures include method calibration, reagent standardization, assessment of each analyst's capabilities, analysis of blind check samples, determination of the method's sensitivity (method detection level or quantification limit), and daily evaluation of bias, precision, and the presence of laboratory contamination or other analytical interference. The details of these procedures, their performance frequency, and expected ranges of results are set out in this manuscript. The specific regulatory requirements of 40 CFR Part 136.7 for the Clean Water Act, the laboratory certification requirements of 40 CFR Part 141 for the Safe Drinking Water Act, and the ISO 17025 accreditation requirements under The NELAC Institute are listed.
