He has worked on oil and gas production valuation and he has written four books (Oil Spills and Gas Leaks, McGraw-Hill, 2014), Environmental Protection and Hydraulic Fracking (Wiley, in press), Acid Mine Drainage (Wiley, 2014), Chromium(VI) (CRC, 2004), MTBE (CRC, 2001). He has worked on hundreds of cases over 25 years, and testified at trial or deposition more than 10 times. As a driller, engineering contractor, he has testified about contracting and safety, exposure, and hazardous wastes, fungi, gasoline, diesel, solvents. He studies vapor intrusion and has testified about sewer collection systems. He has worked on cost recovery actions related industrial, gas stations, and dry cleaner sites. He is a Fulbright Scholar (4 awards) and elected official of a CA community services district and POTW since 2002. He is licensed as a Professional Geologist in AK, AR, CA, ID, OR, PA, TX, WA, WY. He is a Certified Hydrogeologist in CA and WA and he is the qualifying individual for an engineering contractor and drillers license. He is focused on answering geologic and forensic questions related to costs of environmental impairment on real property and mitigation measures. He develops site histories by reviewing reports and augmenting studies by collecting, describing, and analyzing soil, rock, groundwater, vapor and stormwater samples. Other projects relate to peer review and contractor safety and cost evaluation. Since 1990, he has worked extensively on and written widely about the assessment and remediation of soil and groundwater impacted by petroleum hydrocarbons, chlorinated solvents, heavy metals and nitrates. Forensic studies have been used to identify the source of contaminants and likely responsible parties
