Pittsboro, NC – This morning, July 31, the town of Pittsboro received the testing results for 1,4 dioxane in the drinking water system, indicating that the situation is continuing to improve.
The results of these tests, for which samples were taken last Friday (7/28/23), were as follows:
Raw – 2.62 ug/L (-0.08 ug/L)
Finished – 2.29 ug/L (-1.19 ug/L)
Standpipe Tank – 3.50 ug/L (-.09 ug/L)
Million Gallon Tank – 4.09 ug/L (-0.93 ug/L)
Horton Tank – 4.93 ug/L (-0.31 ug/L)
The continued decrease in the concentration of 1,4 dioxane in the raw, finished, and tank water samples indicates that the slug, or concentrated area, of 1,4 dioxane in the Haw River has either already passed Pittsboro or is in the process of passing Pittsboro and has become increasingly heavily diluted.
Additional samples were taken over the weekend and this morning (7/31/23) to verify this continued downward trend in concentrations, the results of which are expected later this week.
To further reduce the amount of 1,4 dioxane in the water distribution system, the town will be flushing the system over the next week.
Additional updates will be provided until the town reaches a non-detectable level of 1,4 dioxane.
