Case Study | Challenging Fast-Moving, High Concentration Chlorinated Solvent Plume Effectively Treated
Hamp, Mathews & Associates, Inc. (HMA), working on behalf of Michigan’s EGLE, collaborated with REGENESIS to develop a highly effective remedial approach to remediate a high-concentration chlorinated solvent plume. The team installed a permeable reactive barrier (PRB) incorporating PlumeStop® and S-MicroZVI® technologies to address the CVOC plume. Within the first month following application, the highest concentrations were reduced by 98%. Three and a half years later, the PRB has maintained effectiveness with chlorinated ethenes reduced by at least 99%.
Case Study Highlights:
- Contaminant levels reduced to at least 99%, maintaining effectiveness for >3 years
- PRB treats CVOCs in high mass-flux aquifer
- Design Verification Testing (DVT) used passive flux samplers (PFS) to better delineate the contaminant mass flux
Webinar Recording | Combined In Situ Biogeochemical Reduction Solution Rapidly Mitigates Threat to River and Saves Client $380,000
Webinar Panel Discussion Highlights:
- Client saves $380,000 following the effective use of FluxTracers to identify and make significant adjustments to horizontal and vertical treatment intervals
- Collaboration on the technology selection process, regulatory approval, and stakeholder buy-in, quickly moves the project forward
- Chlorinated solvent impacts were quickly addressed using strategically applied advanced colloidal technology to halt plume migration, protecting a large river downgradient

Case Study | High Levels of TCE Remediated at Former Chemical Manufacturing Facility, UK
Case Study Highlights:
- Combined ERD/ISCR treatment rapidly and cost-effectively achieves remedial objectives, lowering TCE concentrations by 85% within a year, allowing site redevelopment to move forward
- The in situ application continues to effectively degrade the chlorinated solvent contaminants, reducing the contamination concentrations, overall plume footprint, and exposure risk
- Proven and effective model for plume management strategy for large-scale, high-concentration chlorinated solvent sites, including those with significant DNAPL mass
Webinar | Leveraging Molecular Data and Colloidal Remediation Technologies for Better Site Management
Date: Thursday, September 12th, 2024
Time: 11 am Pacific / 2 pm EasternDora Taggart, CEO of Microbial Insights, will present a case study in which molecular biological tools (MBTs) were used at a fractured bedrock site impacted by chlorinated solvents. Dr. John Freim will then discuss the performance benefits of sulfidated colloidal zero-valent combined with colloidal activated carbon.
Webinar Highlights:
- Overview of the use of molecular biological tools (MBTs) as a crucial line of evidence for comprehensive site management and efficient site closure
- Case study demonstrating the value of MBTs and the efficiency they bring to environmental remediation
- Two brand new field-based tools that enhance the way the environmental industry samples for, and analyzes, microbial communities
- Reactive barriers using colloidal remediation technologies to effectively treat chlorinated solvents and PFAS contaminants
Article | PFAS in Our Water: A Global Problem Demands a Sustainable Solution
Article Highlights:
- Europe’s widespread PFAS contamination affects drinking water for 65% of the population.
- Pump-and-treat remediation is energy-intensive, generates waste, and contributes to climate change.
- A UK study showed in situ remediation costs 1/3 less compared to pump-and-treat methods while providing better long-term effectiveness.
