John C. Hayes, Ph.D., P.E. 

John HayesDr. Hayes has over thirty (30) years of experience in research, teaching and consulting involving hydrology, erosion prevention, water quality sedimentology analysis.  Throughout this period, his primary emphasis has been the impact of changing land use on the environment.  He has focused on providing technical training to contractors, engineers, surveyors, landscape architects involved in urban development.  Co-author of the text, Hydrology and Sedimentology of Small Catchments, Dr. Hayes led technical development of South Carolina’s Certified Erosion Prevention and Sediment Control Inspector (CEPSCI) program.  Since joining Clemson University in 1985, he has been an associate professor, professor, department chair, associate dean for environmental conservation and is now emeritus faculty of BioAg Engineering.  In addition to the CEPSCI program, Dr. Hayes also led development and implementation for a Certified Stormwater Plan Reviewer (CSPR) for South Carolina.  Results from his research and outreach activities are used in the design, installation and inspection of almost all regulated construction sites in South Carolina.  He has also presented numerous workshops and invited papers across the country dealing with design or inspection of erosion and sediment controls and other environmental issues.

Calvin Sawyer, Ph.D.

Cal SawyerCal Sawyer is an Associate Professor in the Department of Agricultural Sciences at Clemson University and the Associate Director of Clemson’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.  He has taught or co-taught nine (9) undergraduate and graduate courses at Clemson, including Soil and Water Conservation, Nonpoint Source Management in Engineered Ecosystems, Vegetative Succession in Restored Ecosystems, and Special Problems in Agricultural Mechanization and Business.  His applied research interests include sediment-bacteria dynamics, turbidity reduction, low impact development and watershed management.

Jeremy Pike

Pike Headshot

Jeremy Pike is an Associate Scientist in the Department of Agricultural Sciences at Clemson University.  He has numerous years of construction and construction management related experience as well as over 15 years of research related experience at Clemson.  His research has focused on water quality and aquatic community responses in relationship with landscape stressors, the majority of which has been related to sedimentation.  He has instructed numerous courses including Stream Ecology, Wetland Ecology, Watershed Management and Techniques in Natural Resources. Additionally, he has presented at national and local meetings on topics including stream restoration, water quality and wetland management.  Pike joined the CEPSCI team in 2014 where he instructs and helps manage the program.  He is currently a Ph.D. candidate at Clemson University and plans to complete his program this year.
