PFAS remediation at DoD sites

DoD Cost Analysis for PFAS Remediation

Date: Thursday, May 22nd, 2025
Time: 11am pacific / 2pm eastern

In this webinar we are pleased to have special remediation expert speaker Dr. Jeremy Birnstingl, REGENESIS Vice President – Environmental Technology. His presentation will discuss a cost analysis for PFAS remediation at DoD sites.

Highlights of this free webinar:

  • Wurtsmith Air Force Base research study – Discloses the high cost the DoD is paying to contain a PFAS plume at an existing pump and treat installation
  • Detailed cost comparison – Comparing the costs of the current system with the costs of an in situ CAC filtration system
  • Pump and Treat will not flush PFAS from the aquifer – even after 100+ years of pumping
  • Over 60% Cost Savings – For the subject site, in situ CAC filtration was shown to be about 1/3 the cost of pump and treat systems over a 30-year period ($7.2M vs $19M)

Leveraging Molecular Data and Colloidal Remediation Technologies for Better Site Management

Molecular biological tools (MBTs) are a crucial line of evidence for comprehensive site management and efficient site closure. Dora Taggart, CEO of Microbial Insights, presented a case study in which MBTs were used at a fractured-bedrock site impacted by chlorinated solvents. The use of in situ microcosms (ISMs) and qPCR, informed key decisions by the consultant which led to selecting a bio+biogeochemical approach using zero valent iron along with biostimulating amendments. Dr. John Freim then presented on 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
