Passive Surface Water Treatment for PFAS
Reduce PFAS migration in stormwater, drainage channels, runoff pathways, and surface water systems with passive treatment barriers designed to immobilize contaminants as water flows through the treatment zone.
Surface Water Can Be the Fastest PFAS Migration Pathway
PFAS present within stormwater, site runoff, drainage systems, and surface water channels can move significant distances during rainfall events. A single storm event may transport contaminants beyond site boundaries, creating regulatory, environmental, and operational challenges. RemBind® Containment Barriers provide a passive approach for intercepting flowing water and reducing PFAS migration before discharge occurs.

What Are RemBind® Containment Barriers?
RemBind® Containment Barriers (RCBs) are passive, in-channel treatment systems designed to intercept flowing water and immobilize PFAS using RemBind® Sorbents contained within replaceable recharge cells. Water flows through the barrier while contaminants are captured within the treatment media. No pumps, power systems, excavation, or engineered treatment infrastructure are required.
Key Benefits
Passive treatment with no pumps or power requirements
Treats water as it flows through the system
Designed to safely pass storm flows over the barrier
Serviceable recharge cells reduce maintenance complexity
No excavation required for routine media replacement
Flexible deployment across a variety of channel sizes and flow conditions
How RemBind® Containment Barriers Work
Step 1: Water Flows Through the Barrier
RCBs are installed perpendicular to flow within drainage channels, runoff pathways, culverts, and other surface water systems. Water naturally passes through the treatment zone without pumps or external power.
Step 2: PFAS Is Immobilized
RemBind® Sorbents within the recharge cells bind PFAS as water moves through the barrier, helping reduce contaminant loading and migration potential.
Step 3: Water Is Treated Progressively
Multiple barriers can be deployed in series, allowing water to receive repeated treatment as it moves downstream.
Step 4: Recharge Cells Are Replaced
Treatment media can be exchanged in place without removing the outer barrier structure.
Typical Applications
