WVDP Phase 1 CSAP12.0 LABORATORY ANALYSESTwo levels of laboratory analyses are called for in this CSAP: rapid and standard.12.1 Rapid Laboratory AnalysesThe first level of laboratory analyses is for rapid-turnaround analyses of Cs-137 and Sr-90 for soils andgroundwater. “Rapid” is defined as results available within 48 hours of sample collection. Rapidturnaround is intended to support situations in which decisions are being made about whether to continuesampling to depth, to extend sampling laterally to bound contamination, or to continue excavation ofcontaminated soils. In these cases, subsequent field activities are contingent on sample results, and rapidavailability of those results is a requirement. “Rapid” turnaround will likely be accomplished bydeployment of on-site, dedicated analytical capabilities for Cs-137 and Sr-90, but may also beaccomplished through the use of expedited shipping and quick-turnaround analyses at an off-sitelaboratory.Although not expected, CSAP data collection activities may determine that other radionuclides are alsosignificant dose concerns and potentially significant decision-drivers for in-field decision-making. If thisoccurs, rapid-turnaround requirements may be expanded to include other radionuclides.The detection limit requirements for rapid-turnaround analyses of Cs-137 and Sr-90 are the same as thosefor standard off-site laboratory analyses. These detection limits may not be required for all samplesanalyzed on-site, but the on-site analytical capacity must exist for meeting these detection limits ifnecessary.The accuracy and precision of on-site methods will be determined and monitored through the use ofcertified standards.Other data quality parameters as described in Section 6.11 and Section 14.0 will also apply.Rev. 1 89
