Laboratory Calibration Calibration is necessary to establish instrument linearity and ensure quantitations are accurate. The laboratory will follow calibration procedures and protocols listed for the each method. Generally, at a minimum, the analytical laboratory will: • Run an acceptable method (reagent) blank; • Perform an acceptable initial calibration to verify instrument linearity; • Use calibration solutions from the National Bureau of Standards or the EPA, whenever such standards are available; • Check, approve, and document commercial standards and reagents for purity prior to use in analysis; and • Document information regarding the preparation of standards, i.e., date, technician, name of each compound and amount used, final volume, and solvent used in a bound standard notebook. Standard containers will have labels indicating the standard type, lot number, and date. The working lifetime of prepared standards will depend on the compound types comprising the standards. The analytical laboratory will follow the manufacturers' or method specified shelf-life recommendations for prepared standards. Corrective Action Because of atypical conditions or unusual incidents, project equipment, field activities, or laboratory analyses may fail to comply with the quality- control guidelines specified in this document. These deviations can affect compliance with the requirements of the remedial activities. Therefore, project and laboratory personnel must document non-conformance with quality control procedures and, as necessarv, implement corrective actions to remedy the non-conformance. Non-conformance means any malfunction, failure, deficiency, or deviation that renders the quality of an item unacceptable or indeterminate. A field worker or a laboratory staff member observing the non-conformance will report it in the field activity log book or laboratory data log. The realm of C-4
