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.

  • Navy’s Portfolio Optimization: In Situ Remediation Sites
  • EPA’s Superfund Optimization Progress Report (2011 – 2015) - Lessons Learned
  • Twenty Years of Multi-Agency Optimization Studies: History, Lessons, & Trends

Mike Singletary, Naval Facilities Engineering Command (Michael.a.singletary@navy.mi)
Mr. Singletary is a registered professional engineer with 20 years of technical and project management experience in soil and groundwater remediation and environmental engineering, working for both the federal government and private sector. Mike works extensively in the planning, design, and implementation of remediation strategies for contaminated sites at Department of Defense (DOD) installations.

Mike supervises, designs, and implements site characterization and restoration programs addressing the requirements of a variety of regulatory programs, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Resource Conservation and Recovery Act (RCRA); and various state environmental cleanup programs.

Mr. Singletary collaborates with the scientific and engineering community (e.g. academia, federal agencies, private industry) to conduct applied research on innovative soil and groundwater remediation technologies and to develop and promote state-of-the-practice technologies for site restoration. Mike participates in research projects through DOD’s Environmental Security Technology Certification Program (ESTCP) and Strategic Environmental Research and Development Program (SERDP).

Mr. Singletary earned a Bachelor's degree in Civil Engineering and a Master of Science degree in Environmental Engineering, both from Georgia Tech. His graduate research focused on the influences of aquifer heterogeneities and reductions in interfacial tension on the migration and entrapment of dense non-aqueous phase liquids (DNAPLs) in the saturated zone. His research also focused on the penetration of DNAPL into low permeability layers facilitated by reductions in interfacial tension.

Mike specializes in groundwater contaminant fate and transport processes, environmental risk management, subsurface remediation of chlorinated solvents and fuel hydrocarbons, bioremediation technologies, and molecular biological tools (MBTs).

Kirby Biggs, U.S. EPA (
Kirby’s work over the past 38 years is very broad-ranging and includes organizational analysis, strategic planning and budgeting, regulation development, policy development, program implementation, cost modeling, expert systems development, training and many other positions and skills. He is expert in State/EPA relations, Superfund grants and contracts regulations, and is knowledgeable of grants law. He has served as a Project Officer, COTR and TCOR for more than 30 years and for many years managed the co-regulator agreement with the Association of State and Territorial Solid Waste Management Officials. Kirby served for 12 years as the EPA Project Officer and Federal Advisor to the Interstate Technology Regulatory Council, a project of the Environmental Council of the States. He has been a team member in many ITRC teams, vetting ITRC project deliverables within EPA and recruiting EPA staff to serve on teams. Kirby has served as a Labor Union steward, national representative, negotiator, and health and safety officer. Prior to joining EPA, Kirby spent seven years in the private sector in credit, finance, manufacturing, and consulting. He received a BA in Economics from the University of Virginia in 1979 and a Master of Public Policy in 1999 from the University of Maryland, specializing in environmental policy.

Kirby’s current position with the Technology Innovation & Field Services Division of the Superfund Office, is National Optimization Program Manager. He leads Superfund National Optimization Strategy Program development and implementation. He leads the National Optimization Team of HQ and Regional staff, managing multiple site-specific optimization projects, both personally and by directing other project managers. These projects involve HQ, Regions, States, and public sector entities conducting Superfund technical support projects throughout the Superfund Pipeline using targeted Investigation technical support, Independent Design Reviews, Remedial System Evaluations, and Long-Term Monitoring and Optimization Studies. Kirby also sponsors development of optimization internet seminars and delivers webinars and classroom optimization courses. He identifies and develops new techniques, methods, procedures and practices to facilitate the closeout of sites and to return them to productive use.
