Horizontal drilling allows remediation to continue while new building goes up on site
Once the tires were gone, CGRS then had to deal with the old building and foundation, including hydraulic lifts that extended out of the ground about 10 feet. While the lifts conveniently retracted into the ground for the shop, they just presented two more obstacles to steer around and avoid while drilling. And, last but not least, the hard lithology would make it difficult to horizontally drill.
“We have since completed the install of the horizontal piping and are preparing to install our injection platform,” Newcomb said. “The plan is that once everything is set up and ready, we will continuously inject the chemical reagent into the formation. The system will be tucked away in the corner of the property and supply the reagent underneath the building while the business operates without interruption.
“And while all of this installation was happening, the general contractor is proceeding with the building demolition, grading of the site and installation of a new building,” he added.
The goal is to reduce onsite contaminant concentrations to less than Tier 2 Site Specific Target Levels (SSTLs). CGRS will begin operating the system once we complete the remediation shed, which will house the injectate metering equipment and bulk chemical, likely in mid-November.
