Description

The site, a former coal-fired power plant in southern Illinois, generated coal combustion residuals (CCR) such as bottom ash and fly ash stored in surface impoundments. Adjacent to the Ash Pond, boron was detected in groundwater above the state standard of 2 mg/L. In late 2025, a groundwater extraction system was installed to control hydraulic conditions and prevent boron migration offsite until source control measures are completed. The system is expected to operate for up to 11 years. Three-dimensional groundwater modelling was used to support system design, helping to identify optimal well locations and flow rates for effective containment. Components, including extraction pumps, tanks, and pipelines, were sized for peak flows and future growth. Pressure transducers in wells allow real-time monitoring, while variable frequency drives (VFDs) on pumps enable flow adjustments and energy efficiency. The system uses pressure transmitters, flow meters, automated valves, and a PLC for automated operation. Four six-chamber bag filter housings remove total suspended solids (TSS). Remote telemetry and data visualization minimize onsite maintenance and allow operators to adjust the system remotely, reducing carbon footprint. Nightly data uploads are displayed on a secure PowerBI dashboard, helping track compliance and remedial progress. The program highlights the integration of advanced automation and telemetry technologies for real-time monitoring, enabling quick responses to changing site conditions and streamlined documentation. Live demonstration segments showcase the user-friendly interface for visualizing system performance and uptime, illustrating how remote access empowers operators and improves remedial outcomes. Attendees leave equipped with practical strategies for implementing similar technologies at their sites, enhancing system reliability, documentation, and sustainability in groundwater containment projects.
