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.”

REGENESIS and AECOM Join the Aviation Pros Podcast: A Solution for the PFAS Problem at Airports

For the aviation industry, PFAS are most commonly found in the foam used to combat airfield fires. Scott Wilson, CEO and President of REGENESIS, was recently featured on the AviationPros Podcast: The PFAS Problem alongside Rosa Gwinn, Global PFAS Technical Leader for AECOM. The episode discusses the harm PFAS pose to people and the environment – and what can be done about them. Listen to the full episode using the link below.

Webinar on PFAS Regulations and a Low-Cost Solution to Eliminate Risk via In-Situ Treatment

In this webinar we are pleased to have as a special guest speaker Rosa Gwinn, PhD PG, Global PFAS Technical Lead at AECOM. Dr. Gwinn’s presentation will take a look at where PFAS regulations started and where they may be headed globally, including the United States. She will be joined by Scott Wilson, President & CEO at REGENESIS, who will share the latest developments about colloidal activated carbon’s use in the remediation industry as a low-cost method of eliminating PFAS risk. The webinar starts Thursday, April 15th, 2021 at 11am pacific/2pm eastern.

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.

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.

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.

Apply Activated Carbon Under Low Pressure to Treat Petroleum Hydrocarbons

PetroFix is an activated carbon remediation technology that is easily injected in situ under low pressure, distributes in the subsurface without fracturing, and includes electron acceptors to stimulate biodegradation of petroleum contaminants in soil and groundwater. This cost-effective technology is designed to remediate petroleum spills and provide immediate results for gas station and UST sites. It works with the PetroFix Design Assistant™, an online design tool that enables users to individually tailor their site designs and self-apply PetroFix.
