ECU Faculty and Students put the ARRRGGHH in W-ARR-ARR-I

Written by: Dr. Guy Iverson, Assistant Professor, ECU Environmental Health Sciences Program

ECU faculty and students were in strong attendance for the 2022 North Carolina Water Resources Research Institute (NC WRRI) on March 23-24, 2022 in Raleigh, NC. Dr. Charles Humphrey, Dr. Guy Iverson and Ms. Avian White authored and co-authored a total of 5 oral and 7 poster presentations. These presentations include the following:

Oral Presentations (*Student author)

  2. C.P. Humphrey Jr., G. Iverson, and M. O’Driscoll. Long-term (7-years) evaluation of a permeable reactive barrier to reduce groundwater transport of nitrate from an onsite wastewater system.
  3. M. O’Driscoll, C.P. Humphrey Jr., G. Iverson, A. Peralta, A. Discepolo*, J. Hoben, J. Gill, C. Carwein, L. Kirby, D. Norris, M. Horstman, and D. Robinson. Bringing light and life back to a buried urban stream in the North Carolina coastal plain.
  4. R. Christian, J. Best*, A. Discepolo*, G. Iverson, M. O’Driscoll, and J.D. Petersen-Perlman. Transdisciplinary approach to understanding low flows and their consequences in a coastal plain river.
  5. H. Miller, H. White, K. Shephard, M. O’Driscoll, and C.P. Humphrey Jr. Town of Nags Head decentralized wastewater management plan update – data analysis of surface water quality, bacteria, groundwater elevations, and subsurface water quality in relation to coastal onsite wastewater treatment systems, future conditions, and community resilience.

NC WRRI is an annual conference that brings together all sectors and disciplines that focus on water resources across North Carolina. This conference creates networking opportunities for water utilities, students, consultants, academics, nonprofits, state agency staff, and many other professions. Research topics include wastewater management, stream restoration, water supply planning, stormwater management, hydrology, community engagement, and many more.
