The Technology Testing and Evaluation Program (TTEP) is an effort to provide reliable information regarding the performance of commercially available technologies that may have application for homeland security. This effort is an outgrowth of EPA's successful and internationally recognized Environmental Technology Verification (ETV) Program. As part of EPAs Office of Research and Development, the National Homeland Security Research (NHSRC) rigorously tests technologies against a wide range of performance characteristics, requirements, and specifications. The technology categories of interest include detection, monitoring, treatment, decontamination, and computer modeling. Stakeholder involvement is important to the success of the program. Stakeholders are engaged in identifying and selecting technologies for testing and in developing test plans. This report presents both quantitative and qualitative results for the spray-applied sporicidal technologies that were evaluated for their effectiveness in decontamination of surfaces. Test coupons that are typical of surfaces found in an office or transportation terminal were selected for the study. The decontamination efficacy results varied by technology, bacterial spore specie, and coupon material. Following testing, the technology vendors were given the opportunity to review and comment on the draft results.
