Key Staff
Charles Ellingson, LHG, RG, PG, CGWP, Senior Hydrogeologist
M.S. Hydrology, 1980, University of Arizona
B.S. Geology/Geophysics, 1978, University of Hawaii
Mr. Ellingson is a co-founder and principal hydrogeologist of Pacific Groundwater Group, bringing the firm nearly three decades of experience in groundwater impact predictions, aquifer protection, contaminant hydrogeology, basin hydrology, and water supply development. His educational background in groundwater hydraulics complements his experience exploring, testing, and modeling a wide variety of groundwater regimes: single- and multi-aquifer systems, unsaturated soils, and shallow groundwater influences on stormwater and wetlands. He has directed groundwater development projects that have involved evaluating regional aquifers, siting and designing wells and well fields, and analyzing impacts to surface water. Mr. Ellingson’s other areas of expertise include groundwater management, contaminant assessment, design of remedial measures, and modeling the hydrologic effects of land use changes. He was an invited participant in the State’s technical advisory committee on hydraulic continuity and co-authored Report of the Technical Advisory Committee on the Capture of Surface Water by Wells, produced for Ecology in 1998. Mr. Ellingson recently managed a multi-disciplinary team to independently assess hydrologic effects from construction of the SeaTac third runway, evaluating potential impacts to groundwater, surface water, and wetlands from an open-pit mining proposal in Thurston County, and leading the groundwater efforts necessary to develop a basin plan focused on groundwater flood mitigation for Salmon Creek in Thurston County.
Daniel Matlock, LHG, Senior Hydrogeologist
M.S. Hydrogeology, 1981, University of Arizona
B.S. Geology (Mathematics), 1977, University of Oregon
Dan has 24 years of experience in many areas related to managing and developing groundwater supplies. His specialties include evaluating and testing regional aquifers, developing plans for wellhead and watershed protection, designing data management systems, assessing water quality, crafting groundwater management strategies, and designing monitoring systems. His extensive background in well hydraulics is an asset to the many water purveyors for whom he has developed well fields, conducted artificial recharge studies, and evaluated surface water and groundwater interactions.
Linton Wildrick, LHG, Senior Hydrogeologist
M.S. Geological Sciences, 1976, University of Washington
B.S. Geology, 1969, Pennsylvania State University
A 22-year veteran of Ecology’s Water Resources Division, Linton brings us his vast experience in hydrogeologic investigations. He has been the primary investigator in many regional studies and has published over 40 papers. He has also lead basin-wide watershed assessments throughout Washington State in a variety of hydrogeologic environments. A special area of Linton’s expertise is the analysis of interactions between surface water and groundwater. While at Ecology, he advised managers and permit writers on hydrologic aspects of water-rights policy and served as the lead scientist on the Technical Committee for Capture of Surface Water by Wells. He has extensive experience as an expert witness in water rights cases.
Burt Clothier, Senior Hydrogeologist, LHG, RG, CWRE
B.S. Geology, 1990, University of Puget Sound
Burt is a Licensed Hydrogeologist with over 25 years of experience. He has managed or led water resource investigations throughout the Pacific Northwest with a special emphasis on Pierce County and South King County. Burt's specialties include regional hydrogeologic interpretations, water well construction, water rights support, and expert witness services. His extensive regional history led to close collaboration on three US Geological Survey groundwater modeling projects, each of which will improve groundwater resource evaluations and management planning efforts.
Burt has built strong relationships with public and private water purveyors and has a long involvement with local watershed planning and modeling in the south Puget Sound. He is the author of dozens of Reports of Examination for water rights applications for the Washington Department of Ecology and frequently consults to develop technical reports of findings. Additionally, Burt served on Ecology’s Well Drilling Technical Advisory Group for nearly 15 years, providing input and oversight of well-drilling industry regulations in Washington.
Inger Jackson, Hydrogeologist, LG, LHG
B.S. Engineering (Geological Environmental Discipline), 1994, Queen’s
University
Inger’s 20+ years of experience in geology, hydrogeology, and geochemistry have focused on designing and implementing field investigations, as well as managing and analyzing data. She has applied her talents to environmental and resource protection projects that have required sampling, well logging, aquifer testing, and designing, installing, and maintaining complex data logging systems to measure water levels and streamflows. She has also helped develop a water-level database that she currently manages. Other capabilities include evaluating chemical data for compliance with MTCA and with the QA/QC requirements of SW-846.
Glenn Mutti-Driscoll, Hydrogeologist, LG, LHG
M.S. Geology & Water Resources Science, 2006, Oregon State University
B.A. Geology, 2002, Earlham College
Glenn has over 13 years of hydrogeologic experience in consulting. Glenn's background includes geologic and hydrogeologic studies, groundwater hydraulics, contaminant fate and transport, geochemistry, and groundwater modeling. Projects that Glenn has been primarily involved with at Pacific Groundwater Group include large-scale infiltration investigations, using groundwater models to evaluate surface water and groundwater interactions, nitrate contamination studies, solid waste landfill monitoring, hydrogeologic characterizations, aquifer analyses, seawater intrusion analyses, assisting clients with water supply development, evaluating water right mitigation approaches, and updating wellhead protection plans.
Jeffrey Parker, Hydrogeologist, LG
M.S., Geology, 2005, University of New Mexico
B.A., Geology, 2002, Pomona College
Jeff has 10 years experience as a consulting Hydrogeologist, in addition to his academic experience. Jeff’s breadth of work includes environmental, water resource, and water rights experience. His detailed study of MTCA rules and experience for a variety of regulatory and remedial approaches achieve technically sound solutions for soil, groundwater, and vapor intrusion sites. Field work experience includes well installation, logging, and sampling of air, soil, and water, with office analytical work such as aquifer tests and environmental statistics.
