Christa Sanderford (MS Environmental Health student) and Guy Iverson (PhD candidate and graduate assistant) also presented at the conference. Christa presented “Evaluation of Fecal Indicator Bacteria Trends in Watersheds with Onsite Wastewater Systems” and Guy presented “Phosphorus and Metal Concentrations and Masses in Residential Septage”.  During the conference, Dr. Humphrey, Christa and Guy led a field tour titled “Soil-based Stormwater and Wastewater Management in Coastal NC”. The tour was in Cedar Point where their research sites were located.
