Thomas R. Mills
Licensed Professional Engineer & Professional Geologist
Mr. Mills has 40 years of professional experience in the geotechnology and environmental fields. During his career, he managed interdisciplinary teams of consultants in several parts of the U.S. working on private- and government-sector projects dealing mainly with soil and ground-water contamination, water-resource development, earth engineering, land reclamation, and water-pollution control. He has performed environmental investigations to characterize environmental conditions and assess risks, and has designed and implemented remedial measures addressing soil and ground-water contamination problems. Mr. Mills also has conducted hydrogeologic investigations for the purpose of siting water-supply wells, defining the hydraulic properties of aquifers, and determining the effects on the environment and other water users due to the pumping of ground water. Furthermore, he has completed geotechnical investigations required in the construction of earthworks, the assessment of geologic hazards, the reclamation of mined land, and the landfilling of solid wastes.
