Dr. O’Reilly has more than 25 years of experience investigating the interaction between environmental and biological chemistry, and spent 15 years as an in-house consultant for a major oil company with a focus on improving remedial technologies. He is a recognized expert in environmental chemistry, petroleum source identification, and bioremediation, and has played a significant role in developing the oil industry’s technical response to managing MTBE in the environment.
Dr. O’Reilly was a founding member of Chevron’s Oil Spill Environmental Functional Team and is trained in aspects of spill management, response, monitoring, and remediation. He has responded to spills of both crude oil and refined products, and served as on-site liaison to environmental regulators. Dr. O’Reilly has provided litigation support in toxic tort and property damage suits, and managed projects related to the remediation of soils, sediments, and groundwater, as well as on optimizing industrial wastewater treatment. Specific contaminants studied include crude oil, refined products, chlorinated solvents, wood treatment compounds, pesticides, and fertilizers. He developed innovative methods for monitoring the transformation and assessing the risk of petroleum. He has also conducted toxicity identification evaluations on refinery effluents and managed waste and water issues on offshore platforms. Experienced working within the constraints of the RCRA, CERCLA, and NPDES programs, Dr. O’Reilly promotes the use of strategic site assessments to reduce costs while improving quality. He has participated in collaborative research projects with regulators at the federal, state, and local levels, and taught technical courses sponsored by regulatory agencies, universities, and industrial trade groups. Dr. O’Reilly is a member of the Washington State Bar and chairs the American Bar Association’s Superfund and Natural Resource Damages Litigation Committee.
