Expert has held Environmental Science, Hydro-geology, Geosciences and Geotechnical roles from 1986 to present. He earned his Ph.D in Hard Rock Geology in 1976.

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

Work History

Years Employer Title Department Responsibilities
Years: 2006 to 2007 Employer: Los Angeles Regional Water Quality Control Board Title: Project Manager and Lead Engineering Geologist Department: Responsibilities: Acted as project manager and Lead Engineering Geologic for hydrogeologic work related to regulatory oversight for the investigation and remediation of soil and groundwater pollution caused by releases from underground tanks, hazardous waste sites, and other sources. Prepared written requests and directive letters for technical reports on remedial investigations, risk assessments, risk management plans, and remedial action plans. Reviewed, evaluated, and provided recommendations on the acceptability of water quality investigations, technical reports, and other actions that address releases of pollutants to soil, groundwater and surface water. Prepared written responses to technical reports regarding their acceptability. Prepared tentative orders for site cleanup requirements for Water Board consideration. Prepared presentations to the Water Board. Performed site inspections to review compliance with site cleanup requirements and approved technical reports (work plans). Proposed and monitors appropriate enforcement action for noncompliance by dischargers or suspected dischargers. Provided guidance to local agencies on appropriate investigation and remediation at local-lead sites. Responded to public and agency requests for information and requests resulting from property transfer and redevelopment activities. Represented the Water Board at meetings with other agencies, the regulated community, and the public.
Years: 2005 to 2006 Employer: MACTEC Engineering Title: Senior Project Hydrogeologist Department: Responsibilities: Responsibilities include supervising Honeywell Projects on several sites in southern and northern California that is impacted by Metals including hexavalent chromium, PCBs, VOCs, SVOCs, and emergent chemicals including Perchlorate and1, 4- Dioxane. The work involved preparation of Remedial Investigation and Remedial Action work plans, negotiations with DTSC and LA-RWQCB, permitting, Treatability studies, preparation of remedial design, and implementation of remedial action plans including environmental construction management.
Years: 2002 to 2005 Employer: Tetra Tech, Inc. Title: Project Manager Department: Responsibilities: 1- Acted as Remedial Project Manager/Resident Contract Engineer representing Honeywell International on several sites in southern and northern California that is impacted by Metals including hexavalent chromium, PCBs, VOCs, SVOCs, and emergent chemicals including Perchlorate and 1,4- Dioxane. The work involved preparation of Remedial Investigation and Remedial Action work plans, negotiations with DTSC and LARWQCB, permitting, Treatability studies, preparation of remedial action plan (RAP), and implementation of the RAP including environmental construction management.

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.

Naval Air Weapons Station (NAWS), Point Mugu, CA. Performed field data collection, evaluation, and reporting to implement a pilot treatability study to determine the feasibility of using either enhanced aerobic or anaerobic biodegradation to remediate trichloroethene, dichloroethene, and vinyl chloride contamination in groundwater.
Years: 1995 to 1996 Employer: Leighton and Associate Title: Consultant Geologist Department: Responsibilities: Managed and performed removals of several large-capacity USTs and associated piping. Projects included remediation of petroleum and chlorinated hydrocarbon-contaminated soil using low-temperature thermal desorption (LTTD) technology. Activities included obtaining excavation, grading, and treatment permits from regulatory agencies; excavation and in situ treatment of more than 40,000 tons of contaminated soil; and supervision of compacting backfill.
