City of Alamosa Evaluates In-Situ Electrogenerated Generated Ferric Reagent to Replace Bulk Ferric and Support Arsenic Removal

While the EPA is reviewing its MCL recommendations for arsenic, utilities are preparing for the possibility of a more stringent federal standard by evaluating the efficacy of their existing arsenic removal treatment systems. Concerned with having to increase their reliance on bulk chemicals to meet a lower arsenic MCL and the associated inherent concerns, the City of Alamosa evaluated the SafeGuard™ H2O technology that generates a ferric regent on-site and on demand. Through bench-scale testing of the in-situ generated ferric reagent, the City of Alamosa has shown it can achieve arsenic removal below 1 ppb while reducing chemical use by more than 30% compared to bulk ferric.
