Project Highlight: High Volume, High Flow Recirculation System Leads to Injection Success

At a site in California, a confidential client needed to address groundwater contamination—including EDB, 1,2-DCA, and other compounds of concern—within silty sand, sand, and gravel layers. Cascade was brought in to deliver a large-scale injection program across 86 points using emulsified lecithin substrate (ELS) and SDC-9. With limited working space and challenging lithology, precision was key. Cascade implemented a high-flow recirculation system and leveraged its Pathfinder^TM automation platform to control flow and pressure at each location—ensuring optimized amendment delivery with minimal disruption.

• Multi-Point, High-Flow Injection System: Teams used high-flow pumps and a manifold setup to inject into 30+ locations simultaneously, streamlining operations and maintaining production rates.
• Pathfinder Precision Control: The automated system enabled customized flow and pressure settings per location, minimizing daylighting and keeping injections on track; even in variable well conditions.
