Principals & Associates
Janet Knox, LG, Principal Environmental Geochemist
M.S. Geochemistry, 1982, University of Auckland
B.S. Geochemistry, 1980, Yale University

Janet has over 22 years of experience in the investigation and remediation of soil, sediment, surface water, and groundwater. She has crafted sampling and analysis programs to assess the types, sources, and receptors of contamination, and she has occasionally served as an expert witness in complex environmental litigation. Her innovative strategies reflect a commitment to keep up with the changing world of environmental cleanup and its many regulations. An active participant in the MTCA Policy Advisory Subcommittees, Janet helped make MTCA more scientifically defensible and practical.
Charles Ellingson, LHG, CGWP, Principal Hydrogeologist
M.S. Hydrology, 1980, University of Arizona

Charles (“Pony”) has 23 years of consulting experience in the areas of aquifer protection, contaminant hydrogeology, waste isolation and monitoring, and water supply. His educational background in groundwater hydraulics complements his experience working in a variety of groundwater regimes: tidal- and multi-aquifer systems, unsaturated soils, fractured aquifers, and two-phase flow systems. His other areas of expertise include developing groundwater management strategies, assessing the distribution of contaminants, designing remedial measures, and modeling the effects of waste disposal practices.
Daniel Matlock, Principal 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.
Russell Prior, Principal Hydrogeologist
B.S. Geology, 1979, University of Washington
Licensed Well Driller, Washington State

With over 24 years of experience in water resource and environmental investigations, Russ has conducted and managed many wellhead protection, groundwater development, and remediation projects. Many of these projects have involved characterizing the regional and local hydrogeology, designing groundwater monitoring and remediation systems, and negotiating with state and federal agencies. One area of his expertise is the design and testing of large-capacity municipal supply wells; another is his extensive knowledge of the geology of Washington, where he has mapped many different environments.
Stephen Swope, LHG, Principal Hydrogeologist
M.S. Hydrology, 1990, University of Idaho
B.S. Geology, 1985, Claremont McKenna College

For over 15 years, Steve has conducted hydrogeologic and environmental site assessments, developed water supplies, and managed multidisciplinary WRIA basin assessments — regional-scale studies of water use and availability, habitat, and water rights. He has also supervised Superfund investigations on the nature, extent, fate, and transport of contaminants. One of Steve’s specialties is developing data management systems for water resources information and statistical analysis plans for landfill monitoring. His experience also extends to the areas of groundwater modeling, wellhead protection, and expert witness / litigation support.
Linton Wildrick, Associate 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.
Peter Schwartzman, Associate Hydrogeologist
M.S. Hydrology (Hydrogeology), 1989, University of Arizona
B.A. Geology, 1984, University of Pennsylvania

Peter’s 15 years of hydrogeologic consulting experience has focused on groundwater resource development, site assessment, numerical flow modeling, and contaminant hydrology. His diverse professional responsibilities have included defining complex groundwater flow regimes, analyzing hydraulic data, and assessing interactions between streams, aquifers, and saltwater. He has developed a variety of regional and local groundwater flow models, applying them a wide variety of groundwater management and contaminant transport problems. Peter also has extensive field and an active involvement in international water supply development.
