Barton Well Fields Perchlorate/TCE Contaminated Groundwater Remediation

Project Highlights: 
  • Evaluation of alternative treatment options including ion exchange, membrane process, chemical, electrochemical, and biological reduction.
  • Operation of EDR pilot system for perchlorate treatment over a four-month pilot duration.
  • Developed conceptual designs and costs for perchlorate treatment.
Carollo’s EDR Pilot Study for perchlorate treatment
Carollo’s EDR Pilot Study for perchlorate treatment in Magna, UT.

Magna retained Carollo to identify and evaluate feasible alternatives and to develop conceptual designs and costs for perchlorate treatment of the affected groundwater basin. Carollo evaluated alternative treatment options for perchlorate including ion exchange, membrane process, chemical, electrochemical, and biological reduction. Due to the water quality issue, electrodialysis reversal (EDR) was recommended and pilot tested for perchlorate removal at Magna. The project also evaluated alternatives for VOC treatment such as air stripping, GAC adsorption, and advanced oxidation processes. Carollo operated the EDR pilot system and performed sample collection and analyses over the four-month pilot duration. In this study, Carollo quantified perchlorate removal rates, defined system operating conditions and provided operating and maintenance training for Magna staff at the conclusion of the study. Carollo developed design criteria including equipment, production capacity, treatment facility footprint, waste disposal, distribution system water quality, and cost estimates for the full-scale EDR plant for perchlorate treatment. Carollo is currently preparing preliminary designs for the plant, based on the pilot study results.
