Water-Advanced Oxidation Water Treatment Plant
Dioxane LevelsIn February 2015, the Minnesota Department of Health (MDH) notified the City of New Brighton that the contaminant, 1,4-dioxane (dioxane), had been detected in trace amounts in some of their City's drinking water wells. Since being notified of dioxane in New Brighton's water supply in 2015, the City of St. Anthony has been testing its three wells monthly in addition to the MDH's periodic testing of the City's wells. That testing continues to show low levels of dioxane.
The Minnesota Department of Health has advised that dioxane levels above 1 part per billion (ppb) present a minimal health risk. The amounts of dioxane found in St. Anthony's water are currently below the MDH's recommended limits for dioxane in drinking water.
