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)
