Robert A. (Bob) Gearheart (born 1938) is an emeritus professor of environmental engineering at Cal Poly Humboldt,[1] in Arcata, California.[2]

Gearheart teaches courses in environmental impact assessment, hazardous waste management, water quality management, and Capstone.

His research interests include water and wastewater treatment using appropriate technology, including constructed wetlands.[3] He has been actively involved with a number of public and private sector agencies providing technical support for water supply and decentralized sanitation facilities in developing countries, including Indonesia, Kenya, Ghana, and Sierra Leone.[4][5]

Gearheart is involved with the development of Arcata's Integrated Wetland and Wastewater Treatment Facility and the Arcata Marsh. The Arcata Marsh serves as a sewage treatment plant, a recreation area, a wildlife sanctuary and aquaculture project.

Gearheart earned a Bachelor of Arts in biology and mathematics from North Texas State University in 1964. He went on to attend the University of Oklahoma, where he received his Master of Science in 1965 and a Ph.D. in civil engineering in 1969.[6]
