From Farm to Ash: Deploying an Existing Economical Boron Solution to CCR Groundwater Authors Dr. Ben Amos - United States - Geosyntec Consultants, Inc. Dr. Hariprasad Parthasarathy - United States - Geosyntec Consultants, Inc. Mr. Paul Wegner - United States - Calcon Mr. Peter Schratz - United States - Calcon Abstract Boron is detected frequently at relatively high concentrations at CCR sites. Boron is currently regulated at CCR sites in several states, with the potential for regulation by USEPA at levels that would trigger corrective action. Due to its (geo)chemical properties, boron is not readily amenable to natural attenuation or in situ remediation. Ex situ treatment of boron, though viable, is typically costly, employing conventional technologies like electro/chemical coagulation, reverse osmosis, ion exchange, and adsorption. This presentation introduces a patented, cost-effective ex situ boring treatment technology for boron. The technology uses ion exchange, with cost savings based on on-site regeneration of the resin and production of a useful and commercially marketable product (i.e., borate, a fertilizer). This process has been successfully used at full scale (up to 2,000 gallons per min) for removal of boron from agriculture wastewaters. The technology has been tested at bench scale on groundwater from CCR sites, with successful removal of boron from up to 25 milligrams per liter (mg/L) to below 0.11 mg/L, meeting potential federal and state standards. Additional treatability testing and field-scale pilots are planned to further demonstrate this cost-effective technology for boron removal from the complex matrices associated with CCR impacts.
