Client Spotlight: Jonathan Dziekan

When Jonathan Dziekan, Senior Project Manager and Civil Engineer with Tetra Tech, Inc. chose to pursue a career in environmental consulting, he was hopeful it would combine his keen interest in both field work and technical work. He begins, “Environmental remediation is a great combination of technical work and field/construction operations.” He continues, “In my current role, I am responsible for all aspects of a project, including ensuring the scope of work is executed as contracted and the budget, schedule, and level of quality are met per the clients’ expectations.” Learn more in our client spotlight.

Case Study: PFAS Removed from Aquifer at Hazardous AFFF Site

This case study reviews a Pennsylvania Hazardous Site Cleanup Act (HSCA) project where aqueous film-forming foam (AFFF) extinguished a large fire in the 1980s was the target of an innovative pilot study to address per- and polyfluoroalkyl substances (PFAS). Working closely on behalf of the PADEP, Tetra Tech, a leading provider of consulting, engineering, and technical services worldwide, was principally involved in assessing the options and choosing a technology for the pilot test. This effort led to the decision to conduct a pilot study using PlumeStop®, a patented colloidal activated carbon amendment known to eliminate the risk of PFAS.

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.

Video: Effective PFAS Remediation Makes Way for Brownfield Development

A 25-acre former refinery located in a mixed-use industrial/commercial area was contaminated with PFAS. Benchmark Environmental Engineering & Science, PLLC & TurnKey Environmental Restoration, LLC, a leading engineering and redevelopment consulting company headquartered in Buffalo, NY, engaged REGENESIS for an in-situ remedy that would effectively and economically cut off the plume and prevent migration of PFAS offsite. The site was entered into the New York State Department of Environmental Conservation’s (NYSDEC’s) Brownfield Cleanup Program (BCP) to facilitate its commercial redevelopment.

Sign Up for the Upcoming Webinar with Ryan Thomas, PhD and Sophia Dore, PhD of GHD

In this webinar we are pleased to have as special guests speaker Ryan Thomas, PhD, Associate and Emerging Contaminants Practice Leader and Sophia Dore, PhD, Associate and Director of the Innovative Technology Group at GHD. Their presentation will discuss emerging contaminants with a focus on treatability studies for PFAS and 1,4-Dioxane. They will be joined by Kristen Thoreson, PhD, Vice President of Quality & Process Improvement at REGENESIS, who will discuss the use of colloidal activated carbon in the remediation industry as a low-cost method of eliminating PFAS risk. This webinar starts Tuesday, November 30th, 2021 at 11am pacific/2pm eastern.

Webinar Recording with Leading PFAS Attorney Ned Witte Now Available 

In this webinar, we were pleased to have a special presentation from Ned Witte, Attorney at Godfrey & Kahn, S.C. Ned’s presentation discussed collateral consequences of identifying PFAS as a CERCLA hazardous substance. If enacted, the PFAS Action Act would require the United States Environmental Protection Agency to designate two PFAS, known as PFOA and PFOS, as Comprehensive Environmental Response Compensation and Liability Act “hazardous substances” within one year and to make a similar determination on other PFAS substances within five years. The full recording is now available.

>99% Contaminant Reduction at Largest Train Depot in Northern Europe with PetroFix

This case study reviews the in situ remediation strategy implemented across the largest train maintenance depot in northern Europe, located in Hagalund, Sweden. As part of the remedial application, Swedish remediation contractor Envytech installed a network of additional monitoring wells across the site. This was done to better delineate the plume and identify any unknown contamination prior to the commencement of remediation. Site investigations identified LNAPL across much of the northern area of the site, which required a revised groundwater remediation strategy.
