Understanding PFAS Remediation Using Colloidal Activated Carbon

eBook highlights:

• Colloidal activated carbon (CAC) offers a low-cost, zero-waste PFAS solution
• CAC converts the subsurface into a purifying filter
• How does activated carbon adsorb contaminants and what primary factors govern sorption behavior?
• How does a CAC barrier contain PFAS over the long term?

This eBook delves into the mechanics of in situ remediation of per- and polyfluoroalkyl substances (PFAS) with CAC, explaining how this approach is used to prevent PFAS exposure risk. When applied directly into the subsurface, this patented CAC material effectively converts the subsurface into a purifying filter. Commercially available as PlumeStop® and SourceStop®, these technologies efficiently remove PFAS.

In situ filtration using CAC is increasingly gaining widespread attention as the environmental industry seeks practical and economically viable solutions to remediate PFAS-contaminated sites. With many known benefits, including low cost and zero waste, this approach to eliminating PFAS risk provides significant advantages, including avoiding the need for permanent infrastructure, ongoing operations and maintenance, external power, and the need for PFAS waste disposal.
