Featured Case Study | Sustainable PFAS Remediation

This case study provides a comparison of the environmental impact of long-term in situ sequestration using colloidal activated carbon (CAC) to pump & treat for PFAS treatment. Leading global engineering and consulting firm Ramboll conducted a Life Cycle Cost Analysis (LCCA) and a Tier 2 sustainability assessment using Ramboll’s SURE model. The study concludes that PlumeStop results in a 40-70x lower total carbon footprint than pump & treat and that immobilization with PlumeStop offers significantly lower costs (61-65%) compared to ex situ treatment approaches.

Video | PFAS Contamination? The Fallacy of Pump & Treat

Looking for a way to eliminate the risk of PFAS in soil and groundwater impacting your property? This short video helps outline what you should know if you are considering using a method known as “Pump and Treat” (P&T) to address PFAS. P&T is an expensive, energy-intensive containment strategy which has rarely ever worked to completely flush the aquifer clean. Using it to address PFAS contamination in groundwater is generally just a bad idea. PlumeStop is a proven, more sustainable PFAS treatment solution to effectively treat contaminants at industrial facilities, airports, and military bases. This more cost-effective approach eliminates the risk of PFAS while producing no waste and offers a 98% lower carbon footprint overall as compared to a P&T solution.

Article | The Looming Legacy of PFAS

This article in Aviation Week discusses regulatory updates surrounding PFAS contamination originating from the discharge of aqueous film-forming foams (AFFF) used in fire suppression systems. These regulatory changes are especially relevant to airports and operators of airport hangars. Accidental discharges of AFFF in hangars are not uncommon, and they introduce liability complexities if PFAS contamination is discovered. The article also discusses fieldwork conducted at Martha’s Vineyard Airport, where a PlumeStop test barrier of colloidal activated carbon has been injected to stem the migration of PFAS.

Case Study | In Situ Treatment of Hexavalent Chromium Results in Site Closure

This case study focuses on the successful remediation of hexavalent chromium (Cr(VI)) contamination at a chrome plating facility in the Midwest. Decades of ineffective pump & treat (P&T) operations led to the need for a cost-effective and rapid solution to achieve regulatory closure. Enviroforensics, an environmental engineering and remediation firm, directed the pilot test efforts and subsequent full-scale application of in situ colloidal technologies from REGENESIS. The use of S-MicroZVI and 3-D Microemulsion led to a rapid 99% reduction in Cr(VI) concentrations, securing regulatory closure for this long-standing contaminated site.
