December 2019 Newsletter

After our remediation technical webinar, Eliminating Risk of PFAS Contamination: Low-Cost In-Situ Remediation with Colloidal Activated Carbon, presenter Scott Wilson, President & CEO of REGENESIS, provided answers to all the questions that we were unable to address during the webinar. These questions, along with Mr. Wilson’s responses, shed light on cutting edge in situ remediation strategies for PFAS using colloidal activated carbon, and because of this we are making them all available to the remediation industry.

In this webinar we are pleased to have as a special guest speaker Charles M. Denton, Esq., partner at Barnes & Thornburg LLP and immediate past chair of the firm’s national Environmental Law Department. Charles Denton will provide an overview of the emerging legal and regulatory considerations for PFAS contamination and key topics for the regulated community, including businesses and local governments. He will be joined by Chad Northington, Southeast District Technical Manager at REGENESIS, who will discuss low-cost in situ remediation of PFAS using colloidal activated carbon. This free webinar beings Wednesday, January 15th, 2020 at 11am pacific/2pm eastern.

Charles M. Denton is a partner in the Atlanta and Michigan offices of Barnes & Thornburg LLP and immediate past chair of the firm’s national Environmental Law Department. He focuses his practice on environmental agency enforcement defense, toxic torts and class action litigation, “Brownfields” redevelopment, compliance counseling, insurance coverage, and alternative dispute resolution (ADR). He serves on the Board for the Georgia Chapter of Air & Waste Management Association (A&WMA), is a member of the Georgia Brownfield Association, and the Environmental Law Section of the Georgia Bar; he is also active with the American Bar Association including as past chair of the ABA Environmental Litigation Committee and service on the ABA Section of Litigation’s Council. Mr. Denton is admitted to practice before the United States Supreme Court, D.C. Circuit Court of Appeals, as well as in Georgia, Indiana, Michigan, and Wisconsin state courts. Mr. Denton received his A.B. summa cum laude in 1978 from Ohio University, and his J.D. in 1981 from the University of Michigan Law School in Ann Arbor, Michigan.

Chad Northington is a professional engineer with over sixteen years of experience in the environmental field in the areas of site investigation, remediation system engineering and construction, project management and technical assistance. He currently serves as the Southeast District Technical Manager with REGENESIS. In this capacity, he provides technical sales support for a suite of soil and groundwater remediation technologies and vapor intrusion mitigation technologies.

In this webinar we were pleased to have as special guest speakers John Hesemann, Remediation Technical Practice Leader, and Rick Cramer, Environmental Sequence Stratigraphy Practice Leader of Burns & McDonnell. Their presentation discussed a next generation approach to tackling remediation of complex contaminated sites. They were joined by Craig Sandefur, Vice President of Remedial Applications Development at REGENESIS, who discussed Design Verification Testing (DVT) activities to improve performance results and reduce project costs at contaminated sites.

Rick Cramer is a California licensed Professional Geologist (PG) with over 30 years of environmental experience, and serves as the Remediation Department Manager and Environmental Sequence Stratigraphy Practice Lead with Burns & McDonnell out of their Brea, California office. Rick has a BS degree in geology from University of the Pacific and a MS degree in geology from University of California, Davis. He began his professional career in the petroleum industry, and pioneered the application of sequence stratigraphy to groundwater projects.

John is a Licensed Professional Engineer (PE) with over 21 years of environmental experience, and serves as Burns & McDonnell’s Remediation Technical Practice Leader for Environmental Division. John earned B.S. and M.S. degrees in Geological Engineering from the Missouri University of Science and Technology and is a licensed professional engineer in the states of Connecticut, Illinois, Kansas, Louisiana, Massachusetts, Missouri, and Oklahoma. He has personally led or supported over 100 remediation projects in 17 states, mostly for industrial clients managing risks associated with chlorinated solvents, petroleum compounds, and other recalcitrant contaminants. As Burns & McDonnell’s Remediation Technical Practice Leader, John leads groups of remediation professionals and practitioners dedicated to developing and implementing effective solutions for private and public sector clients.

Mr. Sandefur is the Vice President of Remedial Applications Development at REGENESIS with expertise in the areas of in situ remedial design and applications. He has over 20 years of experience in the area of in situ groundwater remediation. In his current role at REGENESIS, Mr. Sandefur is part of a team of geologists located throughout the United States providing remediation designs and optimized performance for REGENESIS clients.

Under his direction REGENESIS developed it’s pre-application Design Verification Testing (DVT) program. This program consists of a suite of field sampling and testing activities carried out prior to subsurface remedial reagent emplacement. In addition to the field sampling and testing, Mr. Sandefur directed and implemented a series of Passive Flux Meter (PFM) Studies on select sites. He and the REGENESIS design team use high resolution PFM results to identify mass flux zones responsible for contaminant Plume Distribution in the subsurface.

Advances in REGENESIS’ DVT efforts over the past 5 years in the area of Remediation Geology have resulted in significant improvements in the identification and interrogation of contaminant distribution in heterogenous aquifers. These innovations have informed REGENESIS design and application teams and resulted in improved remedial reagent emplacement, project outcomes and costs reductions. As part of this effort Mr. Sandefur pioneered the use of PFM’s in combination with contaminant plume distribution analysis. This effort has led to more accurate identification and estimation of mass flux zone groundwater velocity earlier in the remediation process. Early flux zone detection provides greater accuracy in early phases of reagent selection and design and reduces the number and extent of subsequent revisions in terms of material quantity and application requirements.
