Georgia EPD discusses PFAS contamination and water treatment strategies in Raccoon Creek

In a recent government meeting held in Georgia, officials from the Environmental Protection Division (EPD) addressed pressing concerns regarding PFAS (per- and polyfluoroalkyl substances) chemicals, known for their potential health risks, including cancer. The discussion highlighted the EPD's reliance on scientific guidance from the Environmental Protection Agency (EPA), which categorizes certain PFAS compounds, such as PFOA and PFOS, as likely or probable carcinogens.

As the meeting unfolded, officials detailed the methods being employed to remove these harmful chemicals from drinking water. Two primary techniques were discussed: activated carbon filtration and reverse osmosis. Activated carbon, a more cost-effective solution, can be integrated into existing water treatment facilities, while reverse osmosis, though more effective at eliminating PFAS, comes with a hefty price tag and complex implementation.

The EPD revealed that approximately 30 to 40 public water systems in Georgia are currently affected by PFAS contamination, prompting the need for treatment solutions. One notable case involved the Raccoon Creek Watershed, where elevated PFAS levels led to a consent order aimed at protecting the water supply for the City of Somerville. This order was a response to monitoring data that indicated PFAS levels exceeding health advisories.

Concerns about the financial implications of installing new filtration systems were raised, with officials acknowledging that costs would vary significantly based on the specific needs of each facility. The EPD committed to providing further information on complaints related to PFAS levels, indicating a willingness to enhance transparency around this critical issue.

As the meeting concluded, questions about international standards for PFAS measurement were posed, reflecting a growing interest in how different regions approach this emerging environmental challenge. While the EPD noted that Georgia has yet to establish its own standards, the conversation underscored the ongoing evolution of scientific methods for monitoring these complex chemicals.

This meeting not only shed light on the current state of PFAS management in Georgia but also highlighted the broader implications for public health and environmental safety as communities grapple with the challenges posed by these persistent pollutants.
