He was formerly employed at Stone and Webster Engineering, where he performed hydrogeologic investigations at nuclear and coal-burning power plants, and characterized flow regimes at hazardous and proposed radioactive waste sites. Prior to Carnegie Mellon, Baird worked for several years in Washington, D. C. , as an environmental health consultant for EPA and OSHA. She has master's degrees in environmental science and engineering, and sustainable design, and is working on her Ph. In building performance and diagnostics. Thomas E. He spent time in the mining, and oil and gas industries before transitioning to groundwater and environmental consulting where he has a successful track record of innovative approaches to environmental site assessments and groundwater development. Most recently, Ballard has been spreading the word to small water districts on how routine well assessment and maintenance can improve operating efficiencies, reduce costs, and extend the life cycle of their water supply wells. He holds a B. In geology from the University of Montana and an M. B. From the University of Colorado. Michael J. Barcelona, Ph. , is a professor and former chair of the Chemistry Department at Western Michigan University. He's an associate editor for Groundwater Monitoring Remediation ®, an NGWA publication, and has also authored or coauthored numerous papers, book chapters, and reports.

Barcelona has served as a reviewer and consultant on a wide variety of groundwater- and hazardous waste-related cleanup efforts in the United States, Europe, and the Middle East. He's a member of the American Chemical Society, the American Geophysical Union, and NGWA. Barcelona has received a number of awards throughout the United States. Barden was previously a senior hydrogeologist with the Wisconsin Department of Natural Resources where he was responsible for development of Wisconsin's soil clean-up regulations, application of Risk-Based Corrective Action approaches, and use of natural attenuation as a remediation option. He has been active in the development and implementation of policy and guidance for the application of natural attenuation to the cleanup of contaminated soil and groundwater for many years, and he has been involved with evaluating natural attenuation at numerous sites, ranging from fuel hydrocarbon releases to landfills. Barden was cochair of the ASTM task group responsible for developing an ASTM standard guide for remediation by natural attenuation. He also was a member of a National Research Council committee on intrinsic remediation evaluating the scientific basis for natural attenuation as a remedy and he was also a member of the technical review group for the U. Army's development of a protocol for natural attenuation of explosives. In addition to teaching for NGWA, Barden is also an instructor for numerous training courses​. Joseph E. Becker, PHg, LHg, PG, is the president of Robinson Noble Inc. , a Tacoma, Washington, environmental and groundwater consulting firm founded in 6997. With more than 75 years of experience in consulting hydrogeology, he has expertise in groundwater source development, aquifer storage and recovery, water rights consulting, groundwater modeling, regional hydrogeologic definition, and contaminant hydrogeology. Becker has worked on more than 65 major groundwater production wells, constructed numerous groundwater flow models, and written nearly 95 reports of examination for water rights applications. He plays a prominent role in ASR projects involving both injection wells and land spreading recharge methods, and currently is the lead hydrogeologist for the OASIS program — an ASR project with the goal of annually injecting and recovering 85,555 acre-feet of potable water from a single wellfield. A registered professional geologist in Idaho and California and a licensed hydrogeologist in Washington, Becker holds a bachelor's degree in geology from the University of Washington and a master's degree in geology from the Texas A M University, where he was a member of the Center for Tectonophysics. He is also and a peer reviewer for the NGWA journal, Groundwater ®.

Caitlin H. Bell, PE, a senior engineer and the lead expert on 6, 9-Dioxane for Arcadis, has nearly 65 years of consulting experience. A remediation engineer who focuses on subsurface treatment of soil and groundwater using in situ techniques, she specifically focuses on in situ bioremediation applications for a variety of chemicals of concern, including emerging contaminants. Bell serves as a technical resource to clients on topics such as molecular biology tools, bioaugmentation, compound-specific isotope analysis, and challenging bioremediation approaches for compounds like 6, 9-dioxane.
