This is a two-part webinar series featuring presentations delivered at the Spring 2018 FRTR Meeting. The meeting's goals were to identify and discuss case studies where remediation technologies were successful for a variety of soil and groundwater systems; and to share experiences and lessons learned that contributed to the operation of these successful remediation technologies.

  • Lessons Learned from the Desktop Optimization Effort for FUDS and the Army
  • Lessons Learned Applying Multiple Remediation Technologies at Air Force Plant 4
  • DOE-EM Soil and Water Assistance Team: Technical Support to Complex Sites

Mr. Rothas has over 30 years of environmental remediation and regulatory compliance experience working in manufacturing, corporate, consulting, and USACE positions. Most recently, he has worked as a subject matter expert, project manager, and lead remediation engineer for a wide range of environmental cleanup sites and contaminants, and serves as USACE?s coordinator for its innovative remediation technology program. Mr. Rothas has performed all facets of remediation system design, construction oversight, operation and maintenance, and optimization involving in-situ and ex-situ treatment technologies. His remediation design and operation experience includes the following technologies: groundwater pump and treat systems; in-situ air technologies (e.g., vapor extraction, air sparging); in-situ biological and chemical oxidation treatment; hydrocarbon product recovery; in-situ thermal treatment; and natural attenuation evaluation/modeling. For the USACE Environmental and Munitions Center of Expertise, he has provided subject matter expertise for remediation technologies, and has specialized in remediation system optimization, CERCLA 5-Year Reviews, and technical quality assurance reviews supporting the USACE Districts and USEPA. He has also been an instructor for USACE training classes involving remediation technologies. Past project management experience covers a spectrum of state and federal programs, including CERCLA, state cleanup programs, TSCA, underground tanks, and due diligence property transfers. Mr. Rothas has a B.S. in Chemical Engineering from the University of Illinois and a Masters in Business Administration from Roosevelt University.

Bruce C. Alleman, Ph.D., OTIE (balleman@otie.com)
Have Dr. Bruce Alleman is an environmental engineer/scientist with more than 35 years of laboratory and field experience in the theory and design of physical/chemical and biological treatment technologies for site remediation and treatment of industrial/hazardous wastewater. He designed, conducted, and managed over 200 laboratory and field treatability tests examining the efficacy of treatment processes, and evaluating the potential for field implementation of innovative technologies. He has worked with teams of experts from academia, government research laboratories, Air Force, Navy and Army environmental programs, and environmental consulting firms to conceive, develop, demonstrate and optimize; and then transfer biotic and abiotic remediation technologies to field application. Bruce?s site remediation experience includes site characterization, developing remedial approaches, designing, installing and optimizing soil and groundwater treatment systems. He served as an Expert Remediation Engineer on the Air Force Center for Engineering and Environment?s Environmental Remediation Program — Optimization (ERP-O) review teams, and currently serves as a Technical Expert on AFCEC?s Complex Site Initiative Program. Bruce served as Program Chair on five Battelle Symposia and served as Associate Editor of the Bioremediation Journal.
