1,4-Dioxane Update – Taking Proactive Measures

Although the Environmental Protection Agency (EPA) has not yet set a standard for 1,4-dioxane, GCPWD is not waiting for a resolution. In fact, the District, with oversight from Nassau County Department of Health, has installed a treatment system at Plant No. 8 (which is off-line) to remove 1,4-dioxane through a chemical reaction and UV light. After treatment with chlorine and UV, levels are so low they can barely be detected.

It’s important for consumers to know that 1,4-dioxane is used in everyday household products such as cosmetics, detergents, shampoos, deodorants, sunscreens and more. “We’re concerned about it and we’re taking action to treat our water,” commented the Board of Commissioners. “And while our levels are quite low compared to other parts of Long Island, we’re moving forward to create a solution.”

This pilot program is part of the 2016 Bond Project and if proven successful, the treatment program will be implemented across the District.
