Status Report for the Week of February 4, 2008
TECHNICAL ASSISTANCE
Technical Assistance to Region V: On January 17, 2008, Dr. John Wilson
(GWERD) provided RPM William Ryan with review comments on a contingent
remedial work plan for the Bendix Superfund Site in St. Joseph, MI. A
number of issues were discussed in detail including sample collection
within a slotted auger, well specifications and construction, and
decontamination procedures for equipment as well as drilling fluids and
purge water. Suggestions were also offered concerning the monitoring
program, specifically with regard to sampling frequency and those wells
which are proposed for removal from the long-term monitoring schedule.
In general, the work plan was found to be technically sound.
