They demonstrate that the daughter TBA plume is longer than the parent MTBE plume because of the remedial response at the site in San Diego. A companion paper has been recently published by Rob Sengebush of INTERA and Dru Heagle and Dick Jackson in Environmental & Engineering Geoscience on the Quaternary History and Groundwater Quality in this aquifer.

Dick Jackson will be speaking to University of Toronto students, post-docs and supervisors on Designing and Implementing Large-Scale In-Situ Remedial Injections/Extraction Operations that will be webcast live from the University of Toronto on January 21st.

Cleanup of the municipal aquifer is currently by pump-and-treat remediation.
