Expert has more than 38 years of experience as a geologist. He is a certified hydrogeologist, professional geologist, licensed well driller and general engineering contractor. His most recent work includes forensic analysis related to subsurface events, including pipe breaks, contaminant spills, oil and gas resource valuation estimates, and groundwater contamination. He has worked on a variety of producing and redeveloped oil field properties, EPA Superfund sites, military bases, agricultural and industrial properties. Since 1990, he has been a co-owner of an environmental-engineering consulting and contracting company, where he has performed more than 1,000 projects.

As a publicly elected community services district board member since 2002, he has evaluated numerous environmental challenges, solved sustainability problems, and worked with others as a team leader and member to develop agency policies. He has been involved with the public process of goal setting, data acquisition, development of workplans, and implementation of field projects. He has promoted and supported sustainable environmental practices within the agency, a certified green business which now offers residents recycling of electronic waste, fluorescent bulbs, medicines, batteries, paper and cardboard. In an effort to minimize local groundwater degradation, in 2009, 1 million less lbs of waste were processed by the agency than in 2006. In 2013, the agency won the Marin County Green Business of the Year award due to the successful recycling efforts and reduction in wastes shipped to the local landfills. For mentoring students, he is the AIPG Sponsor of the UC Davis Geology Student Section (since 2010) and Sonoma State University Geology Student Section (since 2016), SRTM University (India, since 2017) and UC Santa Cruz (since 2020).

Projects/ Achievements:
Background: Aquifer Mapping and Potentially Responsible Party Study - Task manager for Preferred Pathways study for National Semiconductor (2-mile long TCE plume) over a two square mile industrial area at a US EPA Federal Superfund Site in Santa Clara, California related to the release of chlorinated solvents, most notably, TCE, through a “dry well.”

• Designed the aquifer mapping study using thousands of groundwater monitoring wells, soil boring, and driller’s reports to define underground channel systems based on lithologic description.
• The information was used to facilitate installation of remedial measures, saving millions of dollars over the annual groundwater monitoring and lack of remedial progress.
• In conjunction with the Preferred Pathways Study, a Potentially Responsible Party (PRP) study was designed and performed in the area to allow other PRPs to be identified. After evaluating over 400 businesses, a ranking system was developed for prioritization.
