What is the Pathfinder?

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.

 

What is It Designed to Address?

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.

 

How Does It Work?

  • Flow control through automated valves that adjust automatically to meet pressure and flow set points.
  • Control of injection pressures, groundwater depth changes, and flows to eliminate fracturing, excessive groundwater mounding, and short circuiting often common with manual flow control systems.
  • Continuous monitoring and data logging of injection rates, volumes, pressures, groundwater levels, and temperatures.

 

Why the Pathfinder?

  • The Pathfinder allows you to set precise shutdown or control setpoints to ensure optimal chemistry distribution and supporting documentation.
  • It can perform with up to 10 simultaneous injection locations in its base configuration. Additional manifolding available.
  • Better distribution and contact results in lower costs and a shorter time frame to achieving remediation goals.
