Impact/Purpose:
The environmental or health problem addressed by the study: Understanding the extent of transient changes in inorganic anion concentrations when using strong-base anion exchange (SBA) resins for the removal of per-and poly-fluoroalkyl substances (PFAS) from drinking water. A general description of the work and results: Batch and column experiments have been conducted to determine the extent of transient changes in inorganic anion concentrations from the use of strong-base anion exchange (SBA) resins. The long-term importance or significance of the findings: Provides essential information on the potential for unintended consequences regarding corrosion control when implementing strong-base anion exchange for PFAS treatment. Who would be interested in or could apply the results (e.g. program or regional partners, general public, local communities): Drinking water utilities, researchers, regulators, engineers, Regions, OW
