Summary of Professional Experience

Mr. Heglie has more than 19 years of experience in hydrogeology and is a Registered Geologist and Certified Engineering Geologist in California and a Registered Professional Geologist in Oregon. His areas of expertise include:

• Hydrogeology, ground water flow modeling, and ground water quality monitoring
• Surface and borehole geophysics applied to remedial investigations
• Litigation support for industrial clients, including ground water and vadose zone transport modeling
• Project management and client/regulatory agency relationships
• Landfill closure design, remedial investigations, monitoring, and leachate/ground water flow modeling

Representative Experience

• Mr. Heglie served as Project Hydrogeologist for investigation of methyl tertiary butyl ether contamination at a retail gasoline service station as part of a regional assessment of impacts to a major southern California well field. He provided oversight for the client of regional assessment activities, which included a detailed basin-wide transient-state ground water flow model, aquifer characterization, and permitting for drinking water treatment.
• Mr. Heglie served as Project Hydrogeologist for litigation support involving impacts to a high-rise building dewatering system from ground water contaminated with petroleum constituents and chlorinated solvents. He completed ground water flow modeling to evaluate the effectiveness of alternative dewatering systems for a multi-level parking garage beneath the high-rise office building. The ground water flow model addressed three-dimensional ground water flow into alternative dewatering systems, ground water flow beneath several former retail service stations, and a source of chlorinated solvent contamination. The analysis of dewatering alternatives considered effectiveness, feasibility, and cost.
• Mr. Heglie served as Project Manager/Technical Lead for a fast-track remedial investigation for a 1,000-acre former ordnance facility slated for redevelopment. He expedited the investigation of numerous large areas of concern by applying screening technologies (surface geophysical and soil vapor surveys). The remedial investigation addressed over 70 potential areas of concern across the facility and evaluated the potential presence of a variety of organic and inorganic compounds related to the fabrication of ordnance components and the manufacture of solid fuel rocket motors, flares, smoke cartridges, and detonators. He directed the preparation of the work plan, supervised the initial phase of field investigation, negotiated with regulatory agencies, managed data reduction and validation, coordinated preparation of a baseline Human Health Risk Assessment and Ecological Risk Assessment, and performed senior review of final reports. The risk assessment work plan incorporated future commercial and residential land use.
• Mr. Heglie served as Technical Lead for investigation of perchlorate and nitrosodimethylamine in ground water at a former ordnance facility in southern California. He completed initial modeling of fate and transport of perchlorate in the vadose zone and ground water to assist in planning remedial investigations and providing initial estimates of soil cleanup goals. He negotiated work plans with regulatory agencies, supervised monitoring well installation, and prepared reports on investigation results.
• Mr. Heglie served as Project Hydrogeologist for litigation support involving manufacturing facilities. He completed ground water and vadose zone modeling studies of fate and transport of chlorinated solvents to explain the source of the chemicals and/or evaluate potential future impacts and the necessity for remediation. He demonstrated that contaminant sources at several sites did not present a significant risk.
• Mr. Heglie served as Project Hydrogeologist for litigation support involving a retail gasoline service station. He completed ground water modeling studies of fate and transport of gasoline constituents for estimation of the probable date of release and evaluation of general cleanup scenarios. He was responsible for soil and ground water sampling, aquifer testing, and general facility inspection. He analyzed local geology and hydrogeology, evaluated soil and ground water quality data, and rendered interpretation of the nature, extent, and potential source(s) of subsurface petroleum contamination.
• Mr. Heglie served as Project Hydrogeologist for litigation support involving petroleum bulk terminals and electronics manufacturing facilities. He was responsible for soil and water sampling and oversight of work by others. He characterized the nature, extent, and source of ground water contamination and used equilibrium partitioning models to explain the observed distribution of contaminants in ground water, soil, and soil vapor. He reviewed and interpreted results of detailed petroleum fuel fingerprinting analyses, which included identification of the 100 largest components of the fuel mixture by gas chromatography/mass spectrometry.
• Mr. Heglie served as Project Hydrogeologist for litigation support for a major petroleum industry client. He completed review of project files for six facilities and provided recommendations for additional investigation and the most appropriate remedial alternatives. He developed cost estimates for site investigation, remediation, monitoring, and site closure for a 6-year period.
• Mr. Heglie served as Project Hydrogeologist for development of Article 5 water quality monitoring and Corrective Action Plans for two solid waste landfills. He evaluated historic data, provided hydrogeologic interpretation, identified constituents of concern, and specified points of compliance and monitoring parameters.
• Mr. Heglie served as Project Hydrogeologist for closure design for a hazardous waste landfill. He was responsible for the numerical modeling of leachate and ground water flow at the 125-acre landfill for the technical evaluation of leachate extraction alternatives. The numerical model accounted for infiltration, subsurface outflow, surface springs, inflow from consolidation of underlying Bay mud, barrier walls, and effects of leachate collection and extraction alternatives. Twelve alternatives were evaluated on the basis of cost, performance, implementation, operation and maintenance, reliability, safety, and leachate disposal impacts. Mr. Heglie designed subsurface components of a leachate collection and removal system.
• Mr. Heglie served as Project Hydrogeologist for a Solid Waste Assessment Test investigation and leachate management plan development for a large municipal landfill. He was active in all phases of the project from investigation design through hydrogeologic interpretation, landfill/leachate characterization, and leachate management planning.
• Mr. Heglie served as Project Manager for stormwater compliance services for a foundry association. He completed a Master Stormwater Pollution Prevention Plan for 60 facilities.
• Mr. Heglie served as Senior Reviewer and Project Hydrogeologist for various underground storage tank site remediations and property assessments.
• Mr. Heglie served as Project Manager for a pilot test of innovative steam injection/vapor extraction technology at McClellan Air Force Base. He completed initial treatability studies and field investigation for site characterization and coordinated efforts of the technology developer, United States Air Force, Environmental Protection Agency site program, and various regulatory agencies.
• Mr. Heglie has varied management and project experience in solid waste, underground fuel and solvent tanks, property assessments, environmental impact reports, and project oversight.
