Simple PFAS Treatment for Existing Groundwater Wells
RemBind® Well Socks provide a practical approach for reducing PFAS concentrations in groundwater using existing monitoring and remediation wells. Filled with RemBind® sorbent technology and installed directly within a well, Well Socks capture PFAS as groundwater moves through the treatment zone, helping remove PFAS mass from the groundwater system.
Unlike many groundwater treatment approaches, RemBind Well Socks can be deployed without major site construction, injection activities, excavation, or additional treatment infrastructure. Once the treatment media reaches capacity, the socks are removed and replaced as needed.

Groundwater PFAS Management Explained
PFAS contamination frequently occurs within groundwater systems impacted by industrial operations, airports, fire training facilities, military sites, landfills, and other historic uses of PFAS-containing materials. Once contamination enters an aquifer, PFAS can migrate with groundwater flow, creating long-term environmental and regulatory challenges.
Traditional groundwater remediation approaches often require significant infrastructure investments, pumping systems, treatment equipment, or long-term management programs. RemBind Well Socks provide a complementary treatment approach that utilizes existing well infrastructure to help remove PFAS mass from groundwater.
What Are RemBind® Well Socks?
RemBind Well Socks consist of a durable nylon outer sock filled with RemBind reagent, a sorbent material engineered to bind PFAS compounds. The socks are placed within groundwater wells where they remain submerged in the treatment interval. As groundwater moves through the well, PFAS compounds are captured by the sorbent media. Once capacity is reached, the socks can be removed and replaced.
The technology is designed to:
- Utilize existing monitoring wells
- Target PFAS-contaminated groundwater
- Remove PFAS mass from groundwater systems
- Minimize infrastructure requirements
- Support long-term groundwater management programs
How RemBind® Well Socks Work
Step 1: Evaluate Existing Wells
Groundwater data and well construction details are reviewed to identify suitable treatment locations.
Step 2: Prepare the Well Socks
The required number of Well Socks is selected based on well depth and treatment interval. The socks are primed with water and connected into a treatment chain.
Step 3: Install Into the Well
The sock chain is lowered into the well and secured at the wellhead. Groundwater then flows through the treatment media during normal well operation.
Step 4: Capture PFAS
The RemBind reagent binds PFAS compounds within the groundwater as water passes through the treatment media.
Step 5: Remove and Replace
Once performance monitoring indicates the media has reached capacity, the socks are removed and replaced as part of ongoing groundwater management activities.
Key Benefits
Uses Existing Infrastructure
Can often be deployed within existing monitoring and remediation wells without significant site modifications.
Easy Installation
Designed for straightforward installation and retrieval using simple field procedures.
Removes PFAS Mass
Captures PFAS compounds within the treatment media, allowing contaminant mass to be removed from the groundwater system when the socks are retrieved.
Minimal Site Disruption
No excavation, major construction, or groundwater extraction systems are required for deployment.
Scalable Deployment
Can be used in individual wells or across larger monitoring networks.
Cost-Effective Groundwater Management
Provides an alternative treatment option that can complement broader remediation programs.
Applications
Airport PFAS Remediation
Support groundwater treatment efforts associated with AFFF impacts and other PFAS-related contamination.
