POSTER PRESENTATION

Use of Liquid Activated Carbon™ Technology for a Barrier Application in Place of a Conventional P&T Hydraulic Control and ERD Remedies with Modeling Results at a Large Chlorinated Plume in Texas

Liquid Activated Carbon™ (LAC), has been used in a barrier application to secure rapid groundwater contaminant reduction via partitioning out of the aqueous phase in a bedrock aquifer in Texas. Numerous private water wells have dispersed the solute plume throughout the site, so arresting plume migration utilizing LAC was implemented as an in situ remedy instead of groundwater extraction for hydraulic control. LAC provides a low-cost, long-term performance monitoring solution by reducing rigorous sampling requirements associated with typical ERD technologies, while providing an alternative to prevent biofouling impacts to the downgradient potable wells. Prior to the barrier application, a high-resolution site characterization was completed to guarantee product delivery into the bedrock aquifer and ensure performance. Additionally, field calibration testing was conducted to confirm the injection porosity and optimize the injection rates necessary to achieve the required ROI for optimal product placement in the sandstone bedrock unit.
