Dr. Richter is a registered civil engineer with more than 40 years of environmental experience, specializing in the environmental fate and transport of hazardous substances and applied environmental chemistry. He has used this expertise to identify sources of contamination and to estimate both indoor and outdoor exposure concentrations used in assessing retrospective, current and prospective risks. Dr. Richter is an expert in the areas of source identification, exposure reconstruction and assessment, chemical fate and transport, and risk assessment as well as water and wastewater treatment, regulatory compliance, and site characterization and remediation.

Dr. Richter has managed numerous site investigations, risk assessments, and remedial actions involving property transfer assessments, hazardous waste facilities, and underground storage tanks. He has particular experience involving PCBs, PAHs, dioxins, heavy metals, petroleum hydrocarbons, especially benzene, chlorinated solvents (PCE, TCE, TCA), 1,4-dioxane, and asbestos. Dr. Richter's regulatory experience includes interactions with personnel at EPA, the California EPA (DTSC, OEHHA, SWRCB), and several California regional air pollution districts and water quality control boards. He has served on several national and local peer review committees regarding direct and indirect exposures to air toxics. From 2006 to 2011, Dr. Richter has taught the computer modeling class "Environmental Applications of Air, Water and GIS Programs" at the University of California, Irvine, Extension. From 1990 to 1999, Dr. Richter taught the graduate class "Hazardous Waste Remediation" at U.C., Irvine. From 1985 to 1988, he taught the graduate class "Advanced Wastewater Treatment" at the University of Southern California. From 1978 to 1983, he was an assistant professor of civil and environmental engineering at Washington State University, where he taught undergraduate and graduate classes and conducted research involving heavy metals and chlorinated solvents.
