Burt Clothier, Senior Hydrogeologist, LHG, RG, CWRE
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.
Inger Jackson, Hydrogeologist, LG, LHG
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
Glenn has over 10 years of combined hydrogeology experience in consulting and academia. Glenn’s background includes geologic and hydrogeologic studies, groundwater hydraulics, contaminant fate and transport, geochemistry, and groundwater and catchment modeling. Projects that Glenn has been primarily involved with at Pacific Groundwater Group include large-scale infiltration investigations for the disposal and reuse of stormwater and reclaimed water, nitrate contamination studies, solid waste landfill monitoring, hydrogeologic characterizations, aquifer analyses, investigating surface water and groundwater interactions, and modeling groundwater flow and contaminant transport.
Jill Van Hulle, Water Resources Specialist
Jill brings to PGG a wealth of experience from her 15 years as an Environmental Specialist with the Water Resources Program at Washington Department of Ecology. She specializes in complicated water-supply projects and has a reputation as an innovative problem solver. She is an expert in Washington’s water laws, implementation of cost reimbursement projects for water-right applications, mitigation proposals, evaluation of existing water rights, and strategic water-use management. She has been actively involved in the development of many of Washington’s water-resource policies and provides clients with assistance navigating the permitting process. She also has experience with Montana’s water laws and policies.
Jeffrey Parker, Hydrogeologist, LG
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.
Travis Klaas, Geologist
Travis’ background includes geologic studies in petrology, mineralogy, stratigraphy and sedimentation. His training also includes numerous geologic field studies. He has used ArcView to examine relationships between lithology and geomorphologic processes as well as investigate land use. He has also conducted groundwater and soil sampling, and mapped small-scale geologic features. Travis has used low flow groundwater sampling strategies on various projects. He is also experienced in performing formal quality assurance and quality control reviews of analytical data following guidelines outlined in the Contract Laboratory Program published by U.S. Environmental Protection Agency.
David Wampler, Geologist/GIS Analyst
David has an Earth science background in geophysics, geomorphology, fluvial and coastal systems, and sedimentary processes. He additionally has significant experience in software development, statistical algorithms, quantitative GIS analysis in ArcGIS and Python, project management, and Phase I geologic and environmental restoration investigations. David has worked on small to large multi-institution private and public projects, and he has a consistent history of providing high-quality results and analyses within project deadlines and budgets. Major projects David has worked on include subsurface mapping for water and compressed-air energy storage, geomorphology analysis of geologic hazards, remote-sensing of surface water storage changes, ecosystem health investigations, groundwater contamination interpolation, and a multitude of smaller GIS investigations in a wide variety of subjects.
Koshlan Mayer-Blackwell, Ph.D.,
Koshlan brings to PGG a multidisciplinary background in environmental economics, biogeochemistry, and contaminant hydrology. His doctoral research focused on molecular and geostatistical approaches for bioremediation forecasting (e.g., reductive dechlorination of solvents and anaerobic degradation of hydrocarbons). Major consulting projects Koshlan has worked on include bioremediation feasibility studies, RCRA / MTCA investigations, superfund cost allocations, and fate and transport investigations in upland and sediments settings. Drawing on extensive experience developing scientific computing infrastructure in SQL, R, and Python, Koshlan demonstrates a commitment to rigorous statistical analysis and informative data visualization.
Wayne Rennick, GIS Analyst
Wayne has over 15 years experience in the public, private, and nonprofit sectors developing GIS solutions to meet customer needs. He applies his broad-based expertise of mapping concepts and data management to groundwater problems. He has worked with a variety of GIS application: ArcView, Arc/Info (ArcMap and Workstation), Spatial Analyst, 3D Analyst, Network Analyst, Avenue, VBA, and HTML. His experience includes developing and managing GIS programs, performing spatial analyses, geocoding addresses, delineating streams, and developing, converting, and documenting data. Wayne has also designed intuitive user interfaces for data management applications.
