Dr. Blayne Hartman received his Ph.D. in geochemistry from the University of Southern California in 1983. He worked for Unocal (Union Oil Company) for 4 years specializing in surface geochemical methods for petroleum exploration. In 1988 he started his own company (TEG) initially providing geochemical exploration services to the oil industry and in 1989 entered the environmental market by offering certified mobile environmental laboratory services in California. In 1998, he co-founded & operated H&P Mobile GeoChemistry, a partnership offering on-site laboratory analysis, direct push environmental sampling, and soil vapor surveys. He sold H&P in 2008 and is currently an independent consultant offering vapor intrusion, soil gas, and analytical support. Dr. Hartman has over 30 years of soil gas experience and 19 years of vapor intrusion experience.
Dr. Hartman is a nationally recognized expert on soil vapor sampling, soil vapor analysis, and vapor intrusion. He has provided training on soil gas methods and vapor intrusion to County and
State regulatory agencies in over 30 states, many of the EPA regions, the DOD, ASTSWMO, and numerous stakeholder groups and consultants. He was an instructor in the EPA-OUST training, ITRC vapor intrusion training, API petroleum vapor intrusion training and ASTM vapor intrusion courses and has given vapor intrusion training in England, Australia and Brazil. He has written numerous articles on the collection, analysis, and interpretation of soil vapor data, including chapters in five textbooks. He has participated in technical workgroups on soil vapor methods for EPA, CA-EPA, CA Regional Water Boards, County of San Diego, ITRC and ASTM, and has reviewed/edited instructional manuals for the EPA OUST and Superfund groups.
Over the past four years, Dr. Hartman has been a contributing author/editor to vapor intrusion and soil gas guidance documents to federal EPA, CA-EPA, San Diego County, ITRC, DOD, API, and more than 25 individual State documents. He has been involved with six research studies with EPA-ORD on soil gas methods, soil gas temporal variations and indoor air variations in 2012, 2011, 2010, 2009, 2008, & 2007.
