AlamedaReuseandRedevelopmentAuthority | 2011-11-02 | 5 | Response to Comments on Status Update for the ARRA Alameda Reuse and Redevelopment Authority Meeting - November 2, 2011 Time Comment Marker Response technologies, which eventually don't work, and cost a lot of Alameda Point. In such cases, a pilot test (a form of money. So, but they, the Navy then is able to make experiment) typically is conducted to evaluate how well the presentations to scientific boards saying that they tried this technology would work. A pilot test of in-situ thermal technology and it did not work.) treatment to treat groundwater was tried at OU-2C and found to be very cost-effective. Alternatively, a pilot test of nano-zerovalent-iron injection was tried at OU-2B and found not to be effective. In both cases, the Navy and the environmental regulatory agencies unanimously agreed the pilot testing (experimenting) was a prudent way to evaluate the promising technology. The principal instance where experimentation with technologies has occurred at Alameda Point is regarding groundwater in another area of OU-2B. In this case, a university and an EPA national laboratory approached the Navy for permission to conduct an experiment on groundwater contamination. The experiment was primarily funded externally, and the information obtained by the project has improved clean-up decision making for OU-2B groundwater. 36:16 An "active cleanup" site on Slide 13 means a site for which The "Active Cleanup" column in the graph on Slide 13 the regulators have signed off on site characterization and includes sites which have completed their RODs and design remedial investigation, and is to move on to Proposed Plans, or implementation of the active remediation is in progress.
