Corrective Action Technology Profile: Groundwater Extraction and Treatment at Coal Combustion Residual Facilities
This report discusses the state of the art in groundwater extraction and treatment (commonly known as “pump and treat” technology) for remedial action at coal combustion residual facilities. A summary of alternatives for management and treatment of extracted groundwater is also provided.
Over the next several years, the federal Coal Combustion Residuals Rule will trigger the closure of many utility-operated coal ash ponds, and groundwater monitoring will likely reveal the need for corrective actions such as barrier walls and geochemical manipulation. This report identifies and evaluates groundwater-related corrective actions that could be integrated with pond closure, with […]
