Validating the Role of PetroFix®Technology for the Remediation Practitioner’s Toolbox
In this webinar we were pleased to have a special presentation by Jack Sheldon, Senior Remediation Specialist at Antea Group. His presentation discussed validating the role of PetroFix®technology for the remediation practitioner’s toolbox. He was joined by Todd Herrington, Global PetroFix Product Manager at REGENESIS.
Case studies featured in this webinar include:
- An excavation/ PetroFix combination that led to site closure at a convenience store in the Upper Midwest.
- A small PetroFix injection grid that polished a site to attain closure in the Pacific Northwest.
- A complex site in the Southeast with numerous groundwater constituents where remediation has been ongoing for more than two decades where PetroFix is now advancing the remediation effort.
- A low concentration BTEX site where a PetroFix injection grid polished a site in the Ohio Valley to attain closure.
The application of in-situ sorption technologies for the remediation of organic contaminants in groundwater has become an important addition to the many remediation options available for site cleanup. A variety of commercial products are available and most incorporate electron acceptors or other amendments to bind contaminants while stimulating biodegradation processes. The PetroFix dual functioning carbon solution technology has established its own unique place in injection grids, barriers, and as an excavation amendment for polishing petroleum hydrocarbon sites. The technology is convenient to apply, has an ideal particle size to maximize sorption, and has an electron acceptor package that optimizes biodegradation.
This webinar will highlight the important role of the nitrate/sulfate electron acceptor package plays in the performance of the PetroFix technology. Four case studies will also be presented that look at application techniques, site chemistry changes, microbial profiles, and lessons learned.

In Situ Remediation within Bedrock: An exploration of the challenges and solutions using case studies in various geological settings
In situ remediation of organic contaminants can become much more challenging when treatment is required within bedrock aquifers. The added challenges include:
- Contaminant distribution within fracture networks and the rock matrix
- Back diffusion of contamination from the primary porosity, during remediation
- Understanding contaminant flux, a function of groundwater velocity and contaminant concentration; and how that effects remedial design
- Wide ranges of concentrations, including the presence of Dense Non-Aqueous Phase Liquid
- Drilling and application costs in bedrock, at depth.
The webinar covers the challenges of the treatment within bedrock aquifers and discusses appropriate resources to help with the design of site investigations for fractured bedrock sites, enabling the deployment of robust in situ remediation and validation strategies.
Jack Shore explains how a range of engineered injectable substrates can be used to overcome these challenges; focusing on in situ anaerobic and aerobic biological degradation, sorption using micron-scale colloidal activated carbon, enhanced desorption coupled with vacuum extraction and in situ chemical oxidation.
The successful use of these techniques, used alone and in combination, is demonstrated through the presentation of four case studies of the in situ remediation of sites impacted with chlorinated solvents, petroleum hydrocarbons and hexavalent chromium. The case studies also present remediation within different bedrock geologies.
The webinar is useful to anyone considering remedial options for sites underlain with bedrock, provides concepts to consider, and examples of remedial options in a variety of situations.

Case Study: Petroleum Contaminants from UST at Non-Detect within 60 Days using PetroFix
In this webinar we are pleased to have as a special guest speaker Gordon Dean, Vice President of Advanced Environmental Technologies, LLC (AET). His presentation discusses a multi-use convenience store site in Panama City Beach, Florida impacted by contamination from a leaking underground storage tank (UST), where PetroFix® Remediation Fluid, a micro-scale carbon suspension with soluble electron acceptors, was applied to reach target goals within 60 days. He is joined by Chad Northington, Southeast District Manager at REGENESIS, and Todd Herrington, Global PetroFix Product Manager at REGENESIS.
Highlights featured in this webinar:
- AET treated high concentration source areas by provding a permanent, in situ sorptive and biologically permeable reactive barrier (PRB) at a UST site
- A cost analysis was conducted to identify a remediation technology that was affordable and would be guaranteed to lower the contaminant levels below the target levels
- PetroFix Remediation Fluid can be applied under low pressure to capture and biodegradate petroleum contaminants

Incorporating CSIA in Vapor Intrusion Investigations
Land Science is pleased to present a webinar with Dora Taggart, President of Microbial Insights, Inc., and Sam Rosolina, PhD, Analytical Chemist and Manager of the Compound Specific Isotope Analysis (CSIA) Laboratory at Microbial Insights. In this webinar, Dora and Sam discuss incorporating CSIA in vapor intrusion investigations. They are joined by Tom Szocinski, CEP, Director of Vapor Intrusion at Land Science, who discusses innovative new vapor barrier technologies that are more protective and more cost-effective.
Learn the following in this free webinar:
- A primer for sites impacted with contaminant vapor intrusion
- How CSIA is being used to fingerprint different contaminant sources
- Using CSIA to help identify the underlying cause of decreased indoor air quality
Many of the contaminants commonly impacting indoor air through vapor intrusion can also be found in a number of house-hold items and products. Are the chlorinated solvents detected in the air originating from the groundwater beneath the building, or is a bottle of adhesive the actual source? Is the benzene detected in the basement a direct result of an upgradient petroleum release, or from the cigarette of the construction worker in the next room? Determining the source of impact is an important first step in investigating vapor intrusion cases and can save time and money in the long run. This webinar serves as a primer for vapor intrusion, and highlights how compound specific isotope analysis is being used to fingerprint different contaminant sources and help to identify the underlying cause of decreased indoor air quality. With the added context of Microbial Insights’ new CSIA database, the results are automatically plotted for you, making it easy to visualize and interpret the data.
