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 called the Pathfinder™ 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 Pathfinder 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.
