1,4 Dioxane is an emerging contaminant that is a likely human carcinogen. Found in groundwater at sites throughout the US, it's a by-product present in products such as paint strippers, dyes, greases, antifreeze, and aircraft deicing fluids, and in some consumer products. 1,4 Dioxane is highly miscible (i.e. mixes well) in water and does not readily biodegrade in the environment.

The substance has been a topic of discussion and concern for NC municipal wastewater dischargers and the state's Department of Environmental Quality (DEQ) since 2014.

The City's Water Resources Department has been investigating the source of 1,4-Dioxane within the city’s sewer collection and wastewater treatment facilities since 2015. Water Resources continues to work proactively with local industries to monitor for the release of this substance through the Industrial Pre-treatment program. Greensboro and Water Resources also have a long and strong working relationship with the NC Department of Environmental Quality (NCDEQ).

Through these partnerships, the City fully commits to developing a management strategy to reduce the release of 1,4-Dioxane into waterways that may potentially impact downstream communities who rely on the Haw River and Cape Fear River for their source water.
