Others think that the two treatment options are effective if there are low levels of 1,4-dioxane to begin with. “If the concentration is already very low, then if you remove 50 percent that can ...
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 ...
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 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.
