Calvin B. Sawyer, Ph.D. is an Associate Professor in the Department of Agricultural Sciences at Clemson University and the Associate Director of Clemsonâ€™s Center for Watershed Excellence. He coordinates development and implementation of numerous Extension projects, including South Carolina's Certified Erosion Prevention and Sediment Control Inspector program. Sawyer routinely provides water quality and stormwater-related information to various clientele groups, including homeowners, community and government officials, public works and planning staffs, engineers, landscape architects, developers, contractors, and other professional decision-makers.
Applied research interests include sediment-bacteria dynamics, turbidity reduction, low impact development and watershed management. In terms of traditional funding models, I have collaborative research totaling $1.4M, with direct funding of $545,000. These extramural research dollars resulted from 11 funded projects by such granting agencies as the US Department of the Interior, the US Environmental Protection Agency, the USDA â€“ National Institute of Food and Agriculture, USDA â€“ Natural Resources Conservation Service, SC Department of Health and Environmental Control, SC Department of Transportation, and the Clemson University Experiment Station.
Although I do not structurally have a research appointment, initiating and sustaining applied research is a cornerstone of my academic activities. I have authored or co-authored 12 articles in peer-reviewed journals and proceedings, with an additional 14 technical reports and Extension-driven publications. I have presented research findings at 22 international, national, regional or statewide professional conferences and given 51 invited lectures at symposia, workshops, professional associations, elected council meetings, state and federal agencies and other universities. In addition, I have served on peer review panels for the SC Sea Grant Consortium, Georgia Sea Grant, the North Carolina Water Resources Research Institute, the SC Family and Community Leaders, and been invited to serve on another panel by the USDA-NIFA Capacity Building Grants program.
Extension and Outreach
My direct Extension programming has concentrated on strategies to effectively inform and educate targeted constituencies about water resources and the role they play in the stateâ€™s economy, environmental health, and overall quality of life. My primary accomplishments are associated with Extension clientele and affiliated instructional activities that address applied water resource issues for local governments, state agencies, businesses, community organizations, professional societies and the general public. These collective efforts tend to fall into one of two broad Extension and/or research areas: 1) development and implementation of state agency-approved environmental certification courses; and 2) refinement and expansion of compliance-based stormwater education programming.
To address demonstrated sediment impairment and respond to a direct request from the SC Department of Health and Environmental Control, I led development and implementation of the Certified Erosion Prevention and Sediment Control Inspector (CEPSCI) program. CEPSCI serves as a model for fostering new Extension clientele yet following the long-standing traditions of Clemson continuing education. Research on erosion and sedimentation conducted at Clemson University is transferred to the construction industry by the most appropriate methods to convey technical information. Since 2009, 3,771 individuals have participated in CEPSCI, resulting in 24,511 continuing education (CE) credit hours recognized by the SC Department of Labor Licensing and Regulation. Further, and perhaps more importantly, more than 3,700 jobs and over $200M in salaries and wages have been supported through implementation of CEPSCI in South Carolina.
