GAC filters remove PFAS from water sources.### McCallah Ferry, a University of Akron researcher, conducted a [study](https://ideaexchange.uakron.edu/honors_research_projects/1800/) on granular activated carbon (GAC) filters to determine if removing PFAS from water is possible. The research confirms that GAC filters effectively remove PFAS, ensuring safe drinking water. In the United States, regulatory bodies oversee municipal water utilities to ensure water quality. However, individuals who rely on private wells lack such protections and face significant challenges in maintaining safe drinking water. Contaminants such as per- and polyfluoroalkyl (PFAS) pose risks because they persist in the environment and accumulate over time. To address this issue, many households use granular activated carbon (GAC) filters to mitigate PFAS contamination in their private wells. But do these filters work? **You can also read:** [Innovative Gel-Filter for PFAS Removal from Water](https://www.plasticsengineering.org/2024/07/innovative-gel-filter-for-pfas-removal-from-water-005546/#!) ## **Assessing GAC Filters Performance** To ensure their effectiveness, the researcher from The University of Akron tested GAC filters for PFAS removal from private wells. The study aimed to determine if granular activated carbon filters reduced PFAS below safe drinking water thresholds and Maximum Contaminant Levels (MCLs). Ferry’s research assessed whether these filters provide secure and clean drinking water. ## **Modeling PFAS Removal Effectiveness** Ferry used a model to assess a SAMSUNG Ice and Water Refrigerator Filter for the study’s objectives. Using pilot-scale data and an open-source diffusion model, she evaluated the filter’s effectiveness against thresholds and MCLs. The statistical analysis focused on median values to address high data variability. The research accounted for different PFAS compounds, ensuring comprehensive insights into filter performance across various scenarios. ## **Optimal PFAS Removal** The results showed that the filter reduced PFAS below Hazard Index thresholds and proposed MCLs during its 300-gallon lifespan. The filter reached maximum capacity for PFAS removal well beyond the recommended replacement schedule. This affirms the filter’s effectiveness in safeguarding against PFAS contamination and underscores the importance of regular maintenance for optimal performance. Particularly, researchers determined that a replacement schedule of every six months is satisfactory for good performance. Diffused model predicted concentrations for a GAC filter resembling a typical household ice and water refrigerator filter for (A) PFOA, PFOS, (B) PFBS, GenX, PFHxS, and PFNA. The graphs indicate that PFAS levels remain below regulatory limits throughout the recorded shelf life of the filter.

The research confirms the filters’ high performance and longevity, stressing the need for regular maintenance. This study underscores the crucial role of reliable filtration systems in managing water quality and safeguarding public health.

There is nothing people can do to ultimately control this. It is found nearly in everything now. Since the earth and waters have become contaminated how could it ever go away? It’s a known carcinogenic. It has caused many health issues. But the main factor is IT IS DEADLY! And the government does not care. It is allowed continued use but all these “forever” chemicals should be banned! I know it and you know it. I lost my mom to cancer over 20 years ago. Sadly I was unaware of these “forever” chemicals then. I certainly wish I would have know. I would have fought back like so many people have done. I hope the producers of these chemicals do not sleep well at night knowing they are killing people and animals on a daily basis.
