Compiled TCP Information

On August 3, 2016, the Technical Track Work group discussed data from the background wells on the Kaiser site. LimnoTech has determined that there may be evidence from a comparison of background well data and that from Kaiser site, along with synoptic river data, of an unknown groundwater source up-gradient of this site, but there is more information needed. Coordinating with the Toxics Cleanup Program in the future may help in the task. However, given the legal restrictions that MTCA/TCP has to work within (for existing and closed cleanup sites, and identification of new sites) this may be a difficult task.

For now, we have compiled list of documents provided to the Task Force regarding Toxics Cleanup Program (TCP) that may be of use in charting a path forward to identify this groundwater source, and how TCP can help to complement this work. If you have additional information that would be useful, please send them to Kara Whitman (kmwhitman@wsu.edu) for posting on this page. Note: these are also posted on the Department of Ecology Publications Page.
