Expert in Hydrogeology, Contaminant Fate and Transport, and Regulatory Liaison
Expert has worked at a number of complex sites reviewing environmental site assessment work plans for geologic and hydro-geological investigations; evaluation of the adequacy of soil and groundwater remediation work plans with respect to site-specific environmental conditions; and moving projects forward in a timely fashion.
His expertise includes development and implementation of proven and innovative remedial designs for soil and groundwater impacted by fuel and/or chlorinated hydrocarbons, such as air sparging/soil vapor extraction (AS/SVE), dual-vacuum extraction, bioventing, in situ bioremediation, in-well air stripping technology, and pump-and-treat and reinjection systems. He has performed geologic and hydro-geologic investigations, underground storage tank (UST) programs, environmental assessments, and remedial actions at known or suspected hazardous waste sites contaminated by PCBs, heavy metals, chlorinated solvents, hydrocarbons, PAHs, and other hazardous substances. He has supervised drilling, well installation, sampling programs, soil-gas survey and hydro-punch investigations as well.
Expert oversaw the cleanup of contaminated sites; treatability studies, pilot tests, and pumping tests; compliance audits; and interactions with clients, regulatory agencies, and contractors. He has developed and prepared technical reports, including field and laboratory data evaluations and interpretations, proposals, work plans, and protocols.
Expert may consult nationally and internationally, and is also local to the following cities: Los Angeles, California - San Diego, California - Long Beach, California - Santa Ana, California - Anaheim, California - Riverside, California - Glendale, California - Huntington Beach, California - San Bernardino, California - Chula Vista, California

2- Fullerton Manufactured Gas Plant (MGP) Site, Fullerton, CA.
Prepared the Preliminary Endangerment Assessment (PEA) report and the Feasibility Study and Remedial Action Work Plan (FS/RAW) in accordance with CalEPA DTSC requirements. The contaminant of concern included polycyclic aromatic hydrocarbons (PAHs), total petroleum hydrocarbons (TPH), volatile organic compounds (VOCs), and heavy metals. The site cleanup activities conducted to comply with a Voluntary Cleanup Agreement (VCA) executed between the DTSC and the Gas Company.
|Years: 1996 to 2002||Employer: OHM/IT Corporation||Title: Technical Lead/ Project Manager||Department:||Responsibilities: Project Lead, Sr. Project Geologist on multimillion-dollar remedial action contract (RAC) for U.S. Department of Navy. The contaminants of concern included petroleum and chlorinated hydrocarbons. Responsible for evaluation of previous RI/FS work, additional site assessment activities to fill data gaps, supplementary groundwater characterization, plume delineation, and feasibility study to support a corrective action plan and Record of Decision (ROD) at the MCAS Yuma station. Supervised several underground storage tank (UST) sites involving site investigation and groundwater characterization and remediation. Prepared Site Closure reports.
Supervised drilling, monitoring well and air sparging well installation, subsurface soil and groundwater data analysis to implement pilot treatability studies for two innovative in situ groundwater remediation technologies – NOVOCs™ and C-Sparge™. The NOVOCs™ technology is a state-of-the-art design of in-well stripping techniques and relies on an airlift pump action to circulate groundwater through a well and simultaneously facilitate transfer of VOCs from the dissolved phase to the vapor phase. The C-Sparge™ technique involves in situ air stripping with microencapsulated ozone. The remedial process consists of in situ combination of stripping and decomposing chlorinated hydrocarbons to harmless by-products.
Developed a comprehensive long-term monitoring plan, corrective action plan, remedial action report, and various site closure reports. The site cleanup activities supported UST and CERCLA regulations. Supervised groundwater monitoring and sampling, data analysis, and quarterly and/or semiannual monitoring. Prepared analytical data evaluation report for groundwater remediation by natural attenuation (RNA). Received a Department of Navy Appreciation Letter for work performed at this site.
