"Wipe sampling is an important technique for the estimation of contaminant deposition on surfaces. Numerous wipe sampling methods exist, and each method has its own specification for the type of wipe, wetting solvent, extraction procedure, and determinative step to be used, depending upon the contaminant of concern. Wipe sampling methods for the purposes of analytical determination of surface contamination largely do not exist for compounds of interest to the homeland security community. The goal of the project is to provide a wipe sampling method or methods and associated method performance data for collecting selected chemical warfare agents (CWAs), CWA degradation products, and toxic industrial chemicals from five types of surfaces (laminate, galvanized metal, bare wood, industrial carpet, and painted concrete). The objective of this testing and quality assurance plan is to present procedures for testing, which will include documenting the performance of the methods at or below residential risk-based cleanup goals. Testing will be conducted under the U.S. Environmental Protection Agency's National Homeland Security Research Center's Technology Testing and Evaluation Program. Note that an addendum has been added to this document as an appendix which addresses modifications to this plan which were made after the start of testing." |
