    KEY EXPERIENCE

    Sediment Experience

    DuPont

    Industrial Sponsor

    Rich represented DuPont as an industrial sponsor of a Cooperative Research and Development (CRD) with the Natural Sciences and Research Council of Canada (NSERC) with Dr. Ptacek at the University of Waterloo. Rich also is a member of the Science Advisor Board for the Ontario Research Fund which also financially supports Dr. Ptacek’s CRD. The primary focus of CRD is the characterization of mercury cycling in the environment and how to sequester mercury from leaching from soil and sediment.

    Mercury is legacy compound from DuPont’s days of producing one of the world’s first man-made fiber (Orlon) and the days of manufacturing mercury fulminate (an explosive). Mercury once in the environment and under anaerobic conditions can methylate by sulfate and/or iron reducing bacteria. Once mercury is methylated, methylmercury can bioaccumulate. Through this program, biochar has been identified as a key material to sequester and transform legacy mercury into less leachable metacinnabar.

    Confidential Client – Colorado

    Technical Lead

    Rich served as the technical lead for the development of methods to close two evaporative process waste water ponds used during the manufacture of Pentaerythritol tetranitrate (PETN) located in Louviers, Colorado.  As part of the project he led the investigation regarding how to degrade PETN using abiotic or biological methods in the lab and then lead a field pilot test of potential the methods.  He also led the development effort to use remote control high pressure water jetting to blend surrounding clean sediment into the PETN hot spots to dilute the PETN thereby reducing its reactive nature and the potential for sympathetic detonation.  Once the reactive nature was reduced organic carbon was mixed with the sediment to stimulate biological degradation of the PETN.  The non-reactive PETN contaminated sediment was then transferred to an on-site landfill and capped.  The ponds were then deemed to be clean closed.

    DuPont

    Lead Technical Resource

    Rich developed state of the art benthic flux chambers (BFCs) for use on soft sediment and a gravel streambed that can measure flux of mercury in the single parts per trillion level. These BFCs were instrumental in the development of the conceptual model of where mercury was methylating in the South River, VA and the Acid Brook Delta in Pompton Lake, NJ.

    Texas Tech University

    Partnering Consultant

    Mr. Landis lead a research effort for DuPont with Dr. Reible at Texas Tech regarding the development and use of thin film diffusion gradient (DGT) probes to assess the biologically relevant pool of mercury in sediment porewater.

    University of Waterloo

    Partnering Consultant

    Rich represented DuPont as one of the two industrial co-sponsors of a Natural Sciences and Research Council of Canada (NSERC) Research Chair at the University of Waterloo addressing groundwater remediation. The primary area of research by the NSERC Chair was research of the reductive dehalogenation reaction caused by cast iron in saturated anaerobic environments to remediate contaminated groundwater. Rich managed the NSERC program for DuPont and had responsibility to conceptualize, develop, and implement methods to address DuPont’s legacy compounds such CT, TCE, CFCs and others that are present in the environment.

    NSERC

    Lead Representative

    Rich was one of the instructors for the Interstate Technologies Regulatory Cooperation (ITRC) Permeable Reactive Barrier Workshop Containment Workshop that was taught to each USEPA region and to over 1000 attendees. The instructors developed the course materials and participated in instruction of the day and a half short course regarding the science and application of granular cast iron to reductively dechlorinate chlorinated compounds in the groundwater. The USEPA, RTDF, and the ITRC awarded the instructors a plaque in recognition of their efforts.

    DuPont, Dow, GE and USEPA

    Lead Technical Resource

    Rich was the lead technical resource for a collaborative effort with DuPont, DOW, GE, and the USEPA as part of the Lasagna Remediation Technology Development Forum (RTDF) and was responsible for the development and field implementation of electrodes and in-situ treatment zones for the project at DOE’s gaseous diffusion plant in Paducah, KY. As part of the project, we developed a no spoils approach to emplacing the electrodes and treatment zones and DuPont was awarded two patents for the technology.

    US Department of Energy – Kentucky

    Technical Lead

    Rich served as the technical lead for the development of the electrodes and in-situ treatment zones for the project and technical lead for the emplacement efforts at DOE’s gaseous diffusion plant in Paducah, KY. As part of the project, he developed an innovative no-spoils approach to emplacing the electrodes and in-situ treatment zones and DuPont was awarded two patents for the technology. The Lasagna project successfully proved that legacy source zone contamination in the tight soils can be remediated. Recently an Electro-Kinetics summit was held at the University of Waterloo with Rich serving as the industrial representative.

    DuPont, DOE, DOD and USEPA

    Lead Technical Resource

    Rich was the lead technical resource for a collaborative effort with DuPont, DOE, DOD, and USEPA to prove out the use of high pressure jet grouting for emplacement of thin diaphragm walls as a means to construct in-situ physical hydraulic containment barriers.  The work was published in a DOE “Greenbook” documenting the effort which Rich is a co-author.

    Confidential Client

    Technical Lead

    Serving as a technical lead for the development of methods to remediate TNT contaminated soil that also contain chunks of pure TNT at a confidential site.  The plan is to gather the TNT contaminated soil from the numerous legacy TNT manufacturing processes from around the shutdown explosives manufacturing facility and bring the material to a central treatment area.  Rich is leading the investigation of how to safely reduce the reactivity of the TNT contaminated soil and chunks of pure TNT, reduce the particle size of the TNT chunks, and how to blend in hydrated lime to degrade the TNT.
