Although research over the last 20 years has shown distribution and contact of in situ chemistries is a key success factor, injection technology has not advanced to reflect the empirical evidence. Cascade spent several years working to change that, and developed a fully-automated injection system (F-ACTS) designed to deliver liquid amendments and colloidal solids like ZVI and activated carbon more effectively in transmissive zones. It addresses the issue of distribution by providing an automated, fine tune-able system that takes human variables out of the equation, while Cascade Chemistries products tackle the problem of persistent contact with contaminants in the subsurface.
The F-ACTS targets the human imprecision that often impacts the success of an injection remediation project. This system can be fine-tuned and fully automated to accurately and effectively distribute amendments in transmissive zones in the correct doses, at the correct times, and at the correct intervals.
