The Haw River Assembly continues to be concerned about the presence of 1,4-Dioxane in Greensboro, Asheboro, Reidsville, and Pittsboro’s drinking water. 1,4-Dioxane is an industrial solvent that has been entering the Haw River via upriver municipal wastewater treatment plants for many years. Monitoring by scientists has shown it to be in high levels in the Haw River. Traditional treatment methods for drinking water do not remove this contaminant. There has recently been some progress in the reduction of the contamination in the river, and in a decision by the Town of Pittsboro to upgrade its treatment methods.

Dr. Detlef Knappe of NC State University presented his latest research on this industrial solvent, to Pittsboro’s Board of Commissioners on Mon. Nov. 28. Latest data shows that the level in PIttsboro’s drinking water, (which uses the Haw River as its source) is now at lower levels, though still too high according to new EPA guidance. It appears that the spotlight on this issue has resulted in lower amounts being flushed by industries into upriver wastewater treatment systems. More needs to be done to stop this pollution at the source, but in the meantime Pittsboro has decided to safeguard its drinking water by adding activated carbon to the treatment methods, which will better protect public health from other chemical contaminants as well.
