We completed the soil vapor survey and three groundwater monitoring wells <br /> OFFICES during the week of March 26-30,2001. We also determined that drilling conditions would not <br /> Boston allow us to complete the deeper well(MW-3)with conductor casing using the hollow stem <br /> Massachusetts auger drill rig. Therefore,we are planning to complete the deep monitoring well next week <br /> Cleveland using the mud rotary technique. In consultation with several drillering experts,we concluded <br /> Ohio that mud rotary is the best technique to insure our ability to install conductor casing to a depth <br /> of 85 feet at this site,which in turn will protect against cross-contamination during drilling <br /> Denver and well installation. <br /> Colorado <br /> Plymouth We plan to begin field work for the final well on Tuesday,24 April 2001. We envision that <br /> Michigan the drilling and well installation will require between two and three days. Once the work is <br /> Hartford completed,we will prepare a site assessment report and submit it to the Regional Water <br /> Connecticut Quality Control Board in accordance with the schedule outlined in your 26 January 2001 letter <br /> Los Angeles to Dan Decker. <br /> Caltfomia <br /> Manchester Joe Weidmann,RG.,will direct this work for Haley&Aldrich.
