Open House 2013
de maximis Project Coordinator discussing the site remediation progress with a group of students from UCONN and Middlesex Community College.
Many topics were discussed, such as thermal treatment, groundwater monitoring, and future work. For more details see the Documents and Links Page for “Open House 2013” Posters and Briefing Book.
Drilling Progress Continues at SRSNE
Views from southwest looking to the northeast.
It has now been over one month of drilling and installation of the in-situ thermal remediation wells. The team is working hard and doing a great job and currently on schedule. Again, one can see the well pairs, which consist of an electrically powered heater well and a vapor extraction well. Installed to date: 201 Heater Wells (HO), 199 Vapor Extraction Wells (VEW), 25 Temperature Monitoring Points (TMP), and 20 Pressure Monitoring Points (PMP).
Drilling Continues

Drilling continues. The vapor extraction wells are located approximately 3 feet from the electrically powered heater wells. In addition the team is installing Temperature Monitoring Points and Pressure Monitoring Points. To date we’ve installed: 109 Heater Wells (HO), 105 Vapor Extraction Wells (VEW), 9 Temperature Monitoring Points (TMP), and 9 Pressure Monitoring Points (PMP). Also, note the air monitor in the foreground.
In-situ Thermal Remediation – Drilling Begins

Boart Longyear begins drilling in-situ thermal remediation (ISTR) wells, which consist of electrically powered heater wells and vapor extraction wells. Installed to date: 24 Heater Wells (HO), 24 Vapor Extraction Wells (VEW), 1 Temperature Monitoring Point (TMP), and 1 Pressure Monitoring Point (PMP).
