Her Ph.D. work was done in Ecology and Environmental Science at Montana State University, Bozeman. Dr. Kirk’s expertise lies in the biogeochemistry of mined materials, and their assessment throughout the mine life cycle. She has completed numerous environmental geochemistry investigations throughout the U.S. and in Canada, South America, and Africa in 30 years of practice. She is a licensed Professional Geologist in the states of Wyoming and Washington, a Registered Member of the Society of Mining, Metallurgy and Exploration, and a Qualified Person under Canada’s NI 43-101.
Lisa also serves as an Assistant Research Professor in Chemical and Biological Engineering at Montana State University, where she works in the Center for Biofilm Engineering (CBE). Lisa’s CBE work is focused on the microbial geochemistry of mined rock and affected water, with a goal of improving strategies for in situ source control. Together, her role as Principal Geochemist at Enviromin and Research Professor at the CBE feed her passion for innovation in environmental and mineral resource management.
Prior to opening Enviromin, Lisa served as Senior Geochemist for Tetra Tech, Maxim Technologies, and Schafer and Associates, where she provided scientific and project management services for gold, silver, copper, talc, phosphate, platinum/palladium, and coal environmental geochemistry projects. She began her professional career in research, working for the Uranium and Thorium/Sedimentary Resources Branch of the US Geological Survey in Denver CO. After many years of consulting, Lisa returned to research as a doctoral fellow of the US DOE Inland Northwest Research Alliance Subsurface Science Research Initiative from 2005 to 2006, and a doctoral fellow of the USEPA Science to Achieve Results (STAR) program from 2007 to 2010, during her doctoral research in subsurface bioremediation of selenium in phosphate mine wastes. She continues her research into the biogeochemistry of mined materials at the Center for Biofilm Engineering at Montana State University.
Lisa grew up in Boston, MA and with her husband Allan, raised two grown daughters. Lisa enjoy life in the mountains of Montana, traveling, and serving as mentors to the MSU chapter of Engineers Without Borders.
Paul D. Williams, PG, CPH, SME-RM
Paul is a Principal Hydrogeologist with 30 years of experience in mining hydrology, including characterization of groundwater systems for permit support, mine dewatering, mine water management, and closure. His most recent experience involved completion of scoping studies, prefeasibility studies, and feasibility studies for gold, copper, zinc, and transition metal deposits in South America, Eastern Europe, and North America. He has been the designated Qualified Person (QP) on three full-scale hydrogeologic feasibility studies since 2014.
Areas of expertise include design and implementation of field and data collection programs, development of water management plans, support of permit applications for various mining processes, development of conceptual hydrogeologic models, and numerical modeling of groundwater systems in support of permitting (NEPA) for open pit and underground mines. In addition, he has worked on water-related issues associated with closure of open pits and underground mines, including poor-quality mine discharge from adits.
Paul received a B.S. in Geological Engineering from Montana Tech and a M.S. in Environmental Engineering from the University of Massachusetts, Lowell. His career focus has been in characterizing groundwater systems and the subsequent modeling of those systems to support permitting efforts and predict mine inflows, mine dewatering requirements, and mine impacts to water resources.
