This article published in Stormwater Digest discusses new NPDES monitoring requirements that are driving preemptive PFAS solutions.
Article highlights:
- EPA has recently added PFAS to the NPDES (National Pollutant Discharge Elimination System) monitoring list
- NPDES promises to be an effective tool for identifying PFAS sources
- PFAS source mitigation solutions include diverting water around PFAS sources, sequestering the contaminants, and preventing their movement in groundwater.
- Often a patented colloidal activated carbon (CAC) material, commercially known as PlumeStop®, is injected into the subsurface to restrict PFAS in-situ
Once PFAS sources are identified, along with their responsible parties, sound economics dictate they be managed sustainably and cost-effectively. Preemptively mitigating PFAS sources and preventing groundwater plume development is a strategy some facility operators are using to address the contaminants before they are found in an outfall discharging to surface water. PlumeStop has been successfully applied to treat PFAS source areas and prevent their movement in groundwater at over 25 project sites worldwide, with more than 100 sites in the planning stages. It is backed by PlumeShield®, a performance warranty program for the in-situ remediation of PFAS.
