John Heiser is an Environmental Research Engineer at Brookhaven National Laboratory (BNL). John came to BNL in 1978 and has investigated various aspects of hazardous and mixed waste management including verification and monitoring technologies for subsurface barriers and cap/cover systems, materials development for subsurface barriers, in-situ containment and solidification/stabilization materials applications. John has been Principal Investigator on many DOE-EM funded projects, such as; "Development of Perfluorocarbon Tracer Technology for Verification of Cover Performance", "Stabilization/Containment Systems", "Hydraulic and Diffusion Barriers in the Vadose Zone Surrounding Buried Waste", "Interim Subsurface Containment Barrier for Underground Storage Tanks" and "In-Situ Stabilization of TRU/Mixed Waste". John was instrumental in developing environmental and long-term performance monitoring applications of the PFT Technology. Current research interests lay in containment and surface cover systems with emphasis on verification and long-term monitoring of performance including leak detection systems for subsurface environmental structures (e.g., barriers, pipes, tanks, etc.)

John has also been involved in the development of DOE criteria for waste forms and in the development of accelerated leach tests including the ASTM accelerated leach test. Other research collaborations have included EPA (domestic and international), NRC, International Pollution Prevention (IPP) and many private sector companies. IPP projects have included collaboration with several Russian research institutes including the "Kurchatov" Institute, Moscow University, and the Research and Design Institute for Power Engineering.

He has served as a member of numerous expert panels, advisory and review boards and currently is a member of the Long-Term Capping Committee for DOE-EM. He has served as chair or co-chair of technical sessions, symposia, and organizing committees for a number of organizations. John has authored numerous papers and book chapters, has been an invited speaker at many national and international conferences and co-authored a patent for improved waste encapsulation.
