Case study highlights:

  • Study concludes that PlumeStop results in a 98% lower total carbon footprint than pump & treat
  • Immobilization with PlumeStop offers >64% lower costs compared to ex situ treatment approaches
  • Colloidal activated carbon (CAC) requires no operational energy, maintenance, or PFAS-saturated waste products

A recent independent sustainability study (full Life Cycle Analysis) conducted by Ramboll, a global environmental consulting and engineering firm, evaluated the use of PlumeStop vs. conventional pump and treat technology to eliminate PFAS. The findings revealed the use of PlumeStop technology would reduce GHG emissions by 98% and would reduce the cost by >64%. This study included a Life Cycle Cost Analysis (LCCA) and a Tier 2 sustainability assessment using Ramboll’s SURE model. The overall Sustainability Assessment Score for PlumeStop was 100% higher than the ex situ, pump & treat alternatives. PlumeStop also exceeded pump & treat in each of the sustainability categories, ‘Environment’, ‘Society’ and ‘Economy’.
