Donald J. Carpenter, Vice President of ARCADIS, has 32 years of experience and has successfully managed many major radiological projects, including those containing Naturally Occurring Radioactive Material (NORM). He has a master’s degree in Geochemistry from the Colorado School of Mines and a B.S. in Geology from Michigan State University. He has experience detailing remedial strategies to both regulatory agencies and the public and has a broad background in applying solution equilibria-based geochemical modeling to NORM sites. This combined expertise has been particularly valuable in modeling treatment processes associated with the remediation of radiologically contaminated sediments and soils.
