Information from QC procedures is used to <br /> demonstrate acceptable levels of performance by the laboratory and to determine the need for <br /> corrective action procedures. <br /> The approved methods, typically EPA-approved methods, outline the associated method QC <br /> samples. It may include QC procedures for instrument calibration and verification, internal <br /> standard responses, calibration and method blanks, method duplicate, as well as control samples <br /> required to evaluate accuracy and precision as it relates to the antapical method. <br /> AECOM <br /> 20 <br />
