About the Speakers

  • Megan Rounds

    Washington State Department of Ecology

    Megan Rounds studied engineering at the University of Idaho. In the private consulting business, her focus was on geotechnical engineering, helping clients to understand the soil properties so the project would have a solid foundation. She started working at Ecology to use her soil knowledge for wastewater systems that use land as their final treatment process. In 2020 I moved to the Solid Waste Management Program. My main focus is the compost emission study to help the compost industry. In her free time, Megan loves to work on remodel projects. When she is not remodeling, she is running with the Flying Irish Running Club.

  • Tom Jobson

    Washington State University

    Tom Jobson has been a professor in Washington State University’s Department of Civil and Environmental Engineering for the past 17 years; specializing in atmospheric chemistry and the measurement of air pollutants. For the past couple of years he has researched emissions of volatile organic compounds from composting for the WA Department of Ecology. Additionally, he has been investigating how wildfire pollutants can impact the wine industry. He and his spouse Rhonda were married in Port Townsend and love to spend time on the coast.

  • Tim O'Niell

    Engineered Compost Systems

    Tim is President and founder of Engineered Compost Systems. During his 31 years in the compost industry, he has worked as a researcher, product developer, facility designer, and a process improvement and permitting consultant.
