Laboratory Data Validation Clause Samples
Laboratory Data Validation. Data validation will be performed by using the most current methods and quality control criteria from SW-846 and the USEPA’s Contract Laboratory Program (CLP) National Functional Guidelines for Organic and Inorganic Data Review (EPA540/R-99/008, October 1999 and EPA540R/R-01-008, July 2002 and October 2004 respectively). Data validation will also be performed in accordance with the appropriate USEPA Region 5 standards. The CLP data review guidance will be used only to the extent that it is applicable to the SW-846 methods; SW-846 methodologies will be followed primarily and given preference over CLP when differences occur. Analytical data used in risk assessments will be 100% validated by a data validator independent of the laboratory to ensure data usability and facilitate data reduction. It is assumed verification samples will be collected and will be 100% validated during remedial action activities, if necessary. Therefore, it is appropriate that the first sample delivery group of the samples to evaluate lateral and vertical extent of COPCs above the appropriate regulatory standards, guidance, and/or site-specific risk-based values will be validated. If no problems are encountered, twenty percent of subsequent data will be validated, unless a problem is encountered with the data (in which case the percent of data to be validated may be increased). Data to evaluate trends in groundwater concentrations are not proposed to be validated.
Laboratory Data Validation. The Analytical Laboratory has responsibility for full validation of report data. Validation of laboratory data occurs within the Analytical Laboratory in accordance with procedures set forth in its quality control/quality assurance procedures. The Analytical Laboratory manager is responsible for determining whether the data is acceptable.
