PetroFix Chosen as Most Cost-Effective Option to Address Petroleum Contaminants at DoD Site
This case study reviews a PetroFix application to address hydrocarbon contaminants at the former Buxton Naval Auxiliary Air Station, located within the Cape Hatteras National Park in the Outerbanks region of North Carolina. The US Navy utilized the site as a submarine monitoring station from 1956 to 1982. The US Coast Guard (USCG) acquired the facility after 1982 and used the site as a logistical, communication, medical, and supply support center. The site contains four areas of investigation which encompass a total area of approximately 50,000 square feet. PetroFix Remediation Fluid was chosen because it is specifically designed to treat PHC plumes stemming from bulk storage, gas station, and UST spills.

7 Reasons to Consider an In-Situ Permeable Reactive Barrier to Treat Groundwater Contaminants
This video outlines 7 reasons to consider an in-situ permeable reactive barrier (I-PRB) to treat groundwater contaminants. If designed intelligently and installed correctly, I-PRBs can be a highly cost-effective and customizable remediation tool that environmental practitioners can use to achieve cleanup goals.

PFAS Webinar Now Available!
In this webinar we were pleased to have as a special guest speaker Rick McGregor, President of InSitu Remediation Services Ltd. His presentation discussed six pilot-scale studies evaluating the in situ treatment of PFAS in groundwater. He was joined by Maureen Dooley, Director of Strategic Projects at REGENESIS, who discussed in situ treatment of PFAS using colloidal activated carbon to eliminate PFAS risk at a low cost.
How Colloidal Activated Carbon Eliminates PFAS Risk and Liability at a Low Cost
PlumeStop colloidal activated carbon utilizes activated carbon finely milled to >2µm (the size of a red blood cell) and suspended in a colloidal fluid to be injected under low pressure into the subsurface. The carbon particles disperse and diffuse, and then adhere to the surface of soil particles, converting contaminated aquifers into purifying filters. The PFAS contamination present in the groundwater is tightly adsorbed onto the PlumeStop in the subsurface, removing it from the groundwater and eliminating the downgradient risk to the region.
