Hazardous and Radioactive Waste Site Remediation Experience

Jack Caldwell's radioactive waste project experience includes senior management or technical consulting roles on the following projects: DOE's UMTRA Project, DOE's Weldon Spring Site Remedial Action Project in Missouri, DOE's Fernald Environmental Restoration Management Project in Ohio, Nevada Test Site, and the ARCO Parks Shallow Land Disposal Project. Selected project activities and roles include:

  • Uranium Mill Tailings Remedial Action Project, Albuquerque, NM. For five years, Jack Caldwell was Manager of Engineering for the Technical Assistance Contractor to the United States Department of Energy on the Uranium Mill Tailings Remedial Action (UMTRA) Project. This project involved successful remediation of 24 uranium mine and mill tailings sites in ten states. Jack Caldwell managed a group of geologists, and civil and geotechnical engineers in the geological and engineering work involved in site selection, site characterization, disposal cell and associated facility design and design review, construction, and surveillance and monitoring.
  • Weldon Spring Site Remedial Action Project, St Charles, Missouri. As a Specialist Engineering Consultant to the DOE's Weldon Spring Site Remedial Action Project, Jack Caldwell prepared specialist reports that support the conceptual design report for the disposal cell for mixed wastes. Work done on this project was the basis of the book written by Jack Caldwell entitled "Principles and Practice of Waste Encapsulation". The book sets out the principles and practices for designing, analyzing the performance of, and constructing mine and other waste disposal facilities that have to endure for very long periods (1,000 years and beyond).
  • ARCO Parks Shallow Land Disposal Facility, Parks, Pennsylvania. This project involved preparation of the Decontamination and Decommissioning (D&D) Plan for the site that included radioactive elements, heavy metals, and organics. Jack Caldwell (as the project civil engineer) and the project team evaluated waste thermal treatment, vitrification, cement solidification, soil washing, vapor extraction, and the design and performance of alternative disposal cells.
