REGENESIS In the News: PFAS-Contaminated Drinking Water – A Growing Concern for Airports

This article published in Airport Business Magazine discusses why PFAS contamination in groundwater is a growing concern for airports, and the role that in situ colloidal activated carbon (CAC) treatments are playing in mitigating risk at airport facilities globally. Read the full article below.

A Proven Approach to Eliminate PFAS Risk at Airport Sites

REGENESIS has applied PlumeStop, a proven colloidal activated carbon remediation technology, to eliminate PFAS risk at airport sites in the US and in Europe. Applied in situ at low pressure, PlumeStop coats the aquifer surface and acts like a purifying filter, removing mobile, dissolved-phase PFAS contaminants from groundwater. PlumeStop replaces costly pump and treat systems and creates zero waste stream. Watch the video to learn more about how PlumeStop eliminates PFAS risk at airport sites.

Eliminate the Risk of PFAS with Colloidal Activated Carbon

In situ remediation with colloidal activated carbon eliminates risk of PFAS contamination in soil and groundwater at a low-cost. By coating flux zones of an aquifer with colloidal activated carbon, a permeable sorption barrier is created in situ, purifying groundwater as it passively migrates. PFAS constituents from up-gradient source zones are rapidly sorbed to the carbon and removed from the mobile dissolved phase. By removing PFAS from the mobile phase, the route of exposure to down-gradient receptors is eliminated, thereby eliminating the down-gradient public health risk associated with PFAS.

Case Study: Large Plume Eliminated Under Main Street, USA

This case study reviews a former dry cleaner site in a small town in western Indiana, where tetrachloroethene (PCE) had spilled and migrated into groundwater, creating a dissolved-phase PCE plume 1,500 feet long and encompassing 340,000 square feet. From the site, the PCE plume tracked along the town’s eastwest running main thoroughfare, U.S. Route 40 – known as the historic “Main Street of America” – lined with commercial and residential properties to the north and south. Patriot Engineering, a leading Midwest environmental consulting firm, headquartered in Indianapolis, specified enhanced reductive dechlorination (ERD) as the most practical and economically viable method to effectively treat the large plume. Patriot’s strategy to achieve closure was to significantly reduce the PCE plume and then to demonstrate plume stability through post-remediation monitoring.

PlumeStop Application Paves the Way for Redevelopment

This case study reviews a contaminated chlorinated solvent site in northern California where advanced design verification testing and predictive modeling methods were used to guide a remarkably successful in-situ remediation effort. PES Environmental, Inc. (PES) of Novato, California, was selected by the developer as their Environmental Consultant for this project. When PES engaged REGENESIS on this project, a better understanding of contaminant flux was needed. By understanding the contaminant flux, a cost-effective remediation plan could be designed, specifically engineered to achieve a project goal. In this case, the goal was to fully remediate the CVOCs in the target treatment areas within two years following application of the treatment approach.

PlumeStop Eliminates Offsite TCE Migration Meeting Site Goals in 60 Days at Industrial Site

This case study reviews the site of a large-scale in situ groundwater treatment of trichloroethene (TCE) at a former industrial manufacturing facility in the Midwest that quickly achieved and then sustained performance objectives. TCE and low concentrations of other chlorinated volatile organic compounds (CVOCs), cis-1,2-dichloroethene, vinyl chloride, and 1,1,1-trichloroethane, were treated using an innovative sorption-enhanced reductive dechlorination (ERD) approach virtually eliminating contaminants by the first monitoring event within 60 days of application. A permeable reactive barrier (PRB), installed at the site property boundary, has maintained 100 percent reduction in TCE for over three years, meeting the application’s performance objectives by cutting off the site’s contribution to a more extensive groundwater TCE plume.

Client Spotlight: Johnathan Reeve

Jonathan Reeve, a Senior Hydrogeologist with EA Engineering, Science, and Technology, Inc. PBC, is drawn to the challenge of contaminated site investigation and remediation because they are like solving a mystery, one clue at a time. He begins, “As a Hydrogeologist, I investigate all of the geologic aspects of contaminated sites, with an emphasis on groundwater movement. Groundwater is a media that is not easily observed and always represents a big puzzle at a site. Putting together the available pieces of evidence to determine the groundwater pathway from a source to a receptor can be quite challenging and gratifying.”

Fuel Spill from Truck Rollover Receives No Further Action Following PetroFix Application

This case study reviews a semi-truck that was hauling gasoline and diesel and overturned into a dry irrigation ditch in Montana. The diesel tanks ruptured and released fuel into the ditch, impacting the shallow water table with petroleum hydrocarbons (PHCs), including benzene, toluene, ethylbenzene, and xylenes (BTEX). The irrigation ditch feeds a larger irrigation canal that empties into the Yellowstone River. In response, an area of approximately 2,500 square feet area was excavated and approximately 800 tons of the grossly impacted soils were removed. Following the emergency response effort, Pioneer Technical Services, Inc. (Pioneer) reviewed the emergency response report, completed a site inspection and met with the property owner to discuss the emergency response clean-up reconstruction methods and materials to be used.
