Dear Mr. Houk:
As you may be aware, the state has been sampling and investigating sources of 1,4-Dioxane in the Cape
Fear River Basin. Sampling performed by the Piedmont Triad Regional Water Authority downstream of
the Eastside WWTP (Outfall 002) has shown elevated levels of this contaminant. Pursuant to 15A NCAC
02B .0505 and .0508, the Division is requiring permitted POTWs discharging elevated levels of 1,4-
Dioxane to sample for 1,4-Dioxane in their plants' effluent once per month using the recently approved
EPA Test Method 624.1 promulgated in the 2017 Methods Update Rule.
Monthly effluent sampling for 1,4-Dioxane at the High Point Eastside WWTP, NCO024210, at Outfall
002 shall commence in November 2618 and results shall be submitted on the POTW's Discharge
Monitoring Reports.
To discuss test procedures and find a lab certified to perform this updated test method, please contact
Dana Satterwhite, Environmental Program Supervisor III, at (919) 733-3908 ext. 202 or via email at
dana. satterwhiteAncdenr.gov.
If you have any questions, please contact me at (919) 707-3600 or at my email address
