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 manufacture of ordnance components. 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 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.

Site Assessment and Remedial Action

• Mr. Heglie served as Project Hydrogeologist for the investigation and remediation at a former petroleum distribution terminal in northern California. Investigation work has characterized the presence of petroleum constituents in soil, soil vapor, ground water, and surface water; it has included extensive monitoring and sampling of the storm drain system which is subject to tidal flow. Mr. Heglie also performed characterization of human health and ecological risks, and developed site-specific cleanup goals.
• Mr. Heglie served at Project Hydrogeologist for the remedial investigation at a large former lumber mill site on the northern California coast. To expedite site characterization work, he employed surface geophysical surveys and direct push sampling of soil and ground water. The investigation addressed the presence of petroleum constituents, solvents, metals, and other organic constituents in fill material, soil, ground water, pond sediments, and springs.
• 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.

Ground Water Flow and Chemical Transport Modeling

• As Project Hydrogeologist for remediation at an active petroleum distribution terminal in Oregon, Mr. Heglie developed a three-dimensional transient-state ground water flow model for the evaluation of remedial alternatives. The MODFLOW model addressed interaction between ground water an adjacent river, and incorporated site features such as a slurry wall and a concrete revetment. The model was calibrated against transient monitoring data, historical river levels, and multiple aquifer tests.
• 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.
• Mr. Heglie performed two dimensional analytical element modeling for ground water extraction system design for petroleum distribution terminals in California and Washington.
• Mr. Heglie has experience with ground water flow modeling and analysis software including MODFLOW/ MODPATH, TWODAN, and AQTESOLV, along with chemical transport analysis software such as BIOSCREEN, SESOIL, versions of the Johnson and Ettinger vapor intrusion model, and other analytical models.

Litigation Support

• 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, data analysis, and interpretation of the nature, extent, and potential source(s) of subsurface petroleum contamination.
• Mr. Heglie served as Project Hydrogeologist for litigation support involving petroleum distribution terminals and electronics manufacturing facilities. 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.
