RCRA Corrective Action
Petroleum Impacted Community
An operations manager of SMA is the project manager of a multi-million dollar investigation / remediation of an area impacted by decades of petroleum marketing in the area. Releases from petroleum facilities in the area have lead to the accumulation free product beneath a residential community. This has lead to the intrusion of petroleum vapors into people’s homes. Project activities have included: design and construction of a soil vapor extraction system to mitigate vapors from intruding homes, investigating the nature and extent of free product beneath the community, and investigating the nature and extent of dissolved phase constituents in groundwater. This has included insuring that the community water supply wells have not been impacted by the petroleum releases. He has also overseen pilot testing to evaluate recovery of free product and the design of a free product recovery system.

Investigation and Remediation Direction
Characterization and Remediation of an Industrial Facility in Indiana
The principal hydrogeologist of SMA is directing all investigation and remediation activities for an industrial site contaminated with TCE and PCE in southeast Indiana. Activities performed to date have included the determination of contaminant migration pathways in soil and groundwater; identification of five source areas of TCE and PCE contamination that were previously unidentified; determination of the extent of contamination in soil and groundwater; negotiating site-specific cleanup objectives; and performing a feasibility study to identify the most effective combination of remedial measures for the site. A groundwater tracer and biological treatment test was performed to determine the velocity of movement in the fractured bedrock system, and to demonstrate the ability to treat the VOCs in the fractured bedrock at the site. |
Remedial Investigation - Vapor Intrusion
Waste Disposal Industry - Landfill
An operations manager of SMA was the project manager of a $2 million+ CERCLA RI/FS for a 50-acre NPL-listed landfill. He managed RI/FS activities, including drilling, installation, and sampling of monitoring wells, leachate wells, and gas probes; environmental sampling of groundwater, soils, leachate, and surface water; and an ecological assessment of the site area. He managed preparation and presentation of technical memoranda and the RI report, and managed the development of the FS. At the completion of the FS, it was discovered that landfill
gas had migrated to a residential subdivision. He managed the emergency installation of a gas extraction system. From the time of discovery, the extraction system was designed, approved by the Illinois EPA, installed and put into operation within eight weeks. The concentration of landfill gas within the subdivision was reduced to well below acceptable levels within three weeks of system startup |
Management of Fixed-Price ERH Remediation Project
Steel Fabrication Company
A principal of SMA managed a guaranteed, fixed-price remediation project for a steel company in Indiana. Electrical Resistive Heating (ERH) was used to heat the subsurface soils and groundwater. Vapor extraction was used to collect approximately 25,000 pounds of TCE that were recovered from the subsurface. The project was completed in approximately 6 months, and all the remediation objectives were met. |
Remedial Design and Remedial Action
NPL Site/Plating Facility
A principal engineer of SMA served as the project manager for remedial design and remedial action activities at an NPL site in Muskegon, Michigan. As a result of past plating activities, soil and groundwater at the site was heavily contaminated with cadmium, zinc, nickel, cyanide and trichloroethylene (TCE). He prepared planning documents and reports for the pre-design field investigation, which included collecting over 100 soil and groundwater samples on the site. He also provided project management and technical assistance support during the pre-design groundwater treatability study and building demolition. As the project manager, he led a team of six engineers during preparation of the design report, specifications and drawings for soil and groundwater remediation. The remedial alternative includes soil vapor extraction, soil excavation and treatment, groundwater extraction and groundwater treatment by air stripping and chemical precipitation. |
Soil and Groundwater Investigation and Remediation
Petroleum Refinery
An operations manager of SMA is currently managing a multi-million dollar soil, groundwater, and LNAPL investigation and remediation project at an active petroleum refinery and distribution terminal in Illinois. The work is being performed pursuant to a Consent Order with the State of Illinois. The investigative work has included the completion of soil borings, nested groundwater monitoring wells, Cone Penetration Testing (CPT) borings, and Rapid Optical Screen Tool (ROST™) borings. Initial remedial efforts have included groundwater pumping for hydraulic control; LNAPL recovery using dual phase extraction, vacuum enhanced skimming, and skimmer pumps; soil vapor extraction; and soil excavation and disposal. |
Dual Phase Vapor Extraction and AS System
Major Independent Midwest Gas and Oil Company, Beatrice, Nebraska
Responsibilities of a senior remediation specialist of SMA included preparation of a Corrective Action Plan, remedial equipment design, fabrication, installation, and ongoing operation and reporting of DPVE. The innovative design of this system allows the DPVE equipment to perform automated air sparging and discharge of recovered groundwater using the DPVE vacuum pump. An aeration system inside of the vapor liquid separator utilized the DPVE vacuum pump to treat recovered groundwater prior to discharge through activated carbon. |
Hydrogeologic Analysis and PRB Design
Industrial Facility in Indiana
The principal hydrogeologist of SMA has recently directed field tracer testing, and performed groundwater modeling analysis of the tracer testing, large-scale operation of a zero valent iron (ZVI) permeable reactive barrier treatment wall for a site in Indiana. The site has elevated concentrations of VOCs (TCE, 111-TCA, cis-1,2-DCE) in groundwater that are flowing to off-site areas and discharging to a local river. He has directed tracer tests to identify the interstitial groundwater velocity within the aquifer sediments at the site to design a ZVI PRB to treat the VOCs prior to traveling across the property boundary. Additionally, he performed aquifer modeling to identify the ability of the PRB to treat VOCs migrating through it during large-scale de-watering at a construction immediately downgradient of the PRB. |
