Subject: 1,4-Dioxane and NCSU Professor
Barbara and | attend a training class yesterday where w/e presented on sampling and water and wastewater
compliance. As part of the day's events was a presentation from a NCSU professor named Detlaf Knappe and he
discussed emerging pollutants for drinking water. He noted 1,4'dioxaneasan emerging pollutant and | have included a
scan ofthe relevant pages from our handouts. The table isofinterest asitnotes concentrations of1,4'dioxanein
finished water from NC drinking water systems across the state and it also notes NCSU's detection of the compound in
the Haw River at 83 uo/L. The data from the water systems was available from the EPA and comes from a requirement
for water systems to monitor for emerging contaminants; compounds that may have drinking water standards
developed for them inthe future. Unfortunately, data on the concentration of the compound in the water system's raw
water isnot available from the EPA (K8r.Knappe'ustatement).
Thought the attached might be of interest.
