The city’s water – before treatment – contains small but concerning amounts of 1,4-dioxane, a chemical labeled by federal authorities as probably carcinogenic.
Prior to the release, 1,4-dioxane was measured at 2.4 parts per billion in the Haw, below the Environmental Protection Agency’s health advisory goal of 35 ppb. After the release, The N&O ...
ERH remediation involves steam stripping, which historically had not been investigated for 1,4-dioxane. At ERH sites, steam stripping was observed to effectively transfer 1,4-dioxane to the vapor phase for subsequent treatment. 99.8% reductions (or greater) in 1,4-dioxane concentrations in groundwater have been documented on recent ERH remediation.
The U.S. EPA began sampling water in the area for 1, 4-dioxane in 2022. According to the National Library of Medicine, 1,4 dioxane in large amounts can cause liver and kidney damage as well as ...
1,4-Dioxane (/ d aɪ ˈ ɒ k s eɪ n /) is a heterocyclic organic compound, classified as an ether. It is a colorless liquid with a faint sweet odor similar to that of diethyl ether . The compound is often called simply dioxane because the other dioxane isomers ( 1,2- and 1,3- ) are rarely encountered.
The chemical, 1,4-dioxane, is deemed likely to cause liver and kidney cancer and other illnesses by the U.S. Environmental Protection Agency. Labeled a contaminant of ...
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. [3] [4] [5] Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency [6] while the composition must be disclosed if the regulator demands it.

The South Burlington Wastewater Treatment Plant, where the slug of 1,4-dioxane made its way into the Haw, has a capacity of 12 million gallons a day and averages seven to eight million gallons daily.
