Story of Summerville GA Raccoon Creek WTP, A case study of a PFAS Lawsuit & Removal Pilot Project

Drinking Water Quality
Description
A Class Action Lawsuit was filed on February 23, 2021, in Summerville Georgia, alleging that multiple large companies illegally discharged toxic per- and polyfluoroalkyl substances (PFAS) into the Raccoon Creek watershed contaminating the raw water supply to the Raccoon Creek Water Treatment Plant that provides drinking water to Summerville Georgia.
In April 2024, the EPA issued final rules regarding PFAS maximum containment level goals for potable water systems that must be achieved within five (5) years or by April 2029.
The City of Summerville tried to eliminate PFAS in their water using GAC. They added a layer of GAC on top of their filters, which is a highly inefficient method of PFAS removal. Removal and disposal of the sludge is very challenging and costly.
CERAFILTEC, a manufacturer of ceramic membrane ultrafiltration solutions, has a PFAS removal technology called Active Cake Layer Filtration (ACLF) that is very efficient and easy to implement.
In mid-2022, CERAFILTEC approached the City of Summerville and offered to donate their membranes as a part of a 3 to a 6-month pilot project that will repurpose one of their traditional gravity filters to become an ACLF membrane filter system to prove that their technology effectively removes PFAS from drinking water.
The client’s consultant teamed up with a local general contractor, electrician, and integrator to repurpose one of their filters, related piping, valve actuators, and instrumentation to become an ultrafiltration ACLF filter.
If the pilot study meets expectations, and removes PFAS from the water, the client will likely convert the entire plant to be an ultrafiltration membrane plant. If this occurs, the plant will experience cleaner water, enhanced production, and PFAS removal from their water.
PFAS removal, destruction and powder activated carbon recovery are included in this presentation.
