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.
