Over the past two years, no groundwater issue has perhaps received as much community focus and attention as polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS, often referred to as perflourinated compounds (PFCs). The U.S. EPA issued a health advisory, limiting the amount of these compounds to 70 parts/trillion which kicked off a nationwide evaluation of local water sources.

Water Online recently spoke with Leo Zappa, Director of Sales for Calgon Carbon’s Municipal Business Unit and a provider of granular activated carbon, one of a handful of technologies for treating elevated PFC levels. “This is not something that is likely to disappear anytime soon,” warned Zappa. “These compounds are still used or derivatives of these compounds. They are used in everything from fast food wrappers, pizza boxes, microwave popcorn bags etc … So we see that as a new emerging contaminant that is going to be on the radar screen for a while.”

Zappa also discussed the chemical compound 1 2 3-trichloropropane (1-2-3 TCP). To hear about some of the treatment alternatives including ion exchange and activated carbon and how they address the problem, listen here:
