G.D. BECKETT, Hydrogeologist & President

Mr. Beckett is the President and founder of AQUI-VER, INC., providing specialized hydrogeologicand environmental consulting services to major petroleum companies, DOD, consultants, and others.
Mr. Beckett is also a research associate and has instructed at San Diego State University where heinvestigates various aspects of contaminant hydrogeology. At a prior company, Mr. Beckett was asenior project manager for major petroleum and industrial clients. He has directed sitecharacterization studies (geologic, hydrogeologic, and chemical), risk assessment, and remediation
designs leading to site regulatory compliance and closure. These job functions require acomprehensive understanding of the controlling chemical, hydraulic, and physical phenomena. Mr.
Beckett has reviewed and/or generated closure strategies for hundreds of sites and has demonstrated
an ability to find effective solutions for even the most difficult problems.
Under Mr. Beckett’s guidance and publishing, AQUI-VER, INC. (AVI) has developed new scientifictechniques and analyses to evaluate mulitphase contaminant transport, remediation, and environmental
risk. These new and rigorous science applications have led to a nearly flawless site cleanup andclosure record. Science has been shown to describe real processes that control site environmental
risk and the design of efficient and effective cleanup systems (as needed). These technical credentials
have allowed Mr. Beckett to provide training to regional regulatory agencies, including the EPA andothers, on behalf of industry groups including the American Petroleum Institute. Mr. Beckett is aleader in the field of non-aqueous phase liquid (NAPL) contamination and cleanup including
petroleum products, solvents, oils, and other compounds.

REPRESENTATIVE PROJECTS_________________________________________________*American Petroleum Institute: Selected contractor for development of a risk-based toolkit
entitled “Evaluating the Necessity of Hydrocarbon Removal from Source Zones: Tools forAssessing Risk Reduction.” This work incorporates multiphase flow and remediation
dynamics with dissolution of chemicals from the LNAPL source to allow users to estimate therisk magnitude and longevity from different release and cleanup conditions. It also allows theuser to consider the risk/benefit of remediation efforts and cost. On a second related API
contract, AVI is building a parameter database pertaining to LNAPL spills and cleanup. AVI
has an extensive in-house LNAPL parameter database, and applies that parametric experienceto new sites, often reducing or eliminating the need for expensive data collection.

*New Pacific Properties - Designed the field ground truth and proof of concept program for amultimillion dollar remediation of a former refinery that required cleanup of free product andrelated chemicals, including MTBE. The remediation program was implemented by IT
Corporation. Using an innovative approach that capitalized on multiphase synergies, thecleanup reduced impacts to below human health-based standards in less than 6-months, anda no further action letter was received from the California Regional Water Quality ControlBoard, effectively allowing development to proceed. Through AVI’s approach, it became
clear the original remediation design by another contractor, using standard and acceptedindustry approaches, was insufficient to meet the cleanup goals for the property because it did
not correctly consider the multiphase aspects of the cleanup.

*

Confidential Client - Designed a state-of-the-science controlled field study of air-sparging tolead to feasibility assessment and design at a hydrocarbon-affected site. Tasks include
numerical modeling, pilot study work plan and direction, refinement of numerical results,feasibility assessment, and system design. The project was part of a Petroleum Environmental
Research Forum (PERF) study on air sparging. The cleanup design predicted operations tobe complete in less than 1 year (for benzene), actual system run-time was 6 months.

*Confidential Client - Performed a Human Health Risk Assessment for a site underlain by aplume containing petroleum compounds above regulatory action levels and overlying a utilized
drinking water aquifer. Rigorous but inexpensive information was collected to ground-truth
the chemical fate and transport component of the risk assessment. Results of the risk
assessment indicated less than de minimis risk and the site received a site closure letter fromthe lead agency (no further action under current site operations and conditions).

*

Confidential Client - In a two-party litigation, performed expert review of opposing sides
aquifer test methodology and analysis that purportedly implicated a major petroleum company
as the 80% responsible party for a petroleum hydrocarbon plume. AVI showed that the test
methodology was invalid and could not be used as evidence for the suggested contaminanttransport. Our work pointed out that the data also were not appropriate as input into risk
assessment or remediation planning studies. Analyses and modeling clearly suggested theother party was likely responsible for most of the impacts and associated costs.
