GlobalASR provides 3rd party analytical data validation for evaluating compliance of the laboratory data received with EPA methods, procedures, or contract specific requirements. Laboratory analytical data is reviewed in accordance with criteria specified latest version of the United States Environmental Protection Agency (USEPA) National Functional Guidelines for Laboratory Data Review, the USEPA Region IX Data Validation Guidance; and the Department of Toxic Substances Control (DTSC) Data Validation Memorandum (Summary of Level II Data Validation, 2006). Where specific guidance is not available, lab data can be reviewed for consistency with industry standards using professional experience and professional judgment by GlobalASR’s data validation team.

 

A project-specific Quality Assurance Project Plan (QAPP) may provide many instructions and project requirements pertaining to (but not limited to) the contaminants of potential concern, field sampling locations, field sampling procedures, sample preservation techniques and analytical data validation criteria. 

The QAPP may also contain specific information regarding the analyses to be performed by a laboratory that includes (but is not limited to) target analyte and/or parameter lists, the analytical and field Quality Control (QC) criteria, along with the hardcopy and electronic reporting requirements. 

GlobalASR’s data validation team reviews the lab data package to ensure compliance to the QAPP and other project requirements that may be contained in the Work Plan(s). GlobalASR has provided data validation services to several projects of Los Angeles Unified School District (LAUSD), California Department of Transportation (CalTrans) and Orange County Transportation Authority (OCTA).
