Final Takeaways

Final Takeaways
• Long and short chain • Service life varies by compound
and background water quality
Both GAC & IX are effective
for removal of PFAS
• Not all media is created equal • Testing is required to accurately
predict service life and determine lowest cost solution
Performance dictates long term costs
