The South Huntington Water District has recently completed the construction and placed into operation three state-of-the-art water treatment systems. These treatment systems , known as Advanced Oxidation Process or AOP, utilize ultraviolet light reactors to destroy the emerging contaminant – 1,4 dioxane. These treatment systems are located  at Plant No. 10 located on Whitson Lane- Huntington Station, Plant No. 3 at Amityville Road in Huntington Station and Plant No. 8 on Old Country Road in Melville. Plant No. 10 was the first AOP treatment system completed within the Town of Huntington. The District has prepared the following video tour of Plant No. 10 below to show the various equipment and treatment systems in place to provide high quality water that meets all drinking water standards water to your tap everyday.

An Inside Look at Your Water Treatment

What are the health effects of 1,4-Dioxane?
Laboratory studies show that 1,4-Dioxane caused liver cancer in animals exposed at high levels throughout their lifetime. Other types of cancer have also been reported, although less consistently than liver cancer. There is no evidence of 1,4-Dioxane cancer effects in humans. The United States Environmental Protection Agency considers 1,4-Dioxane a likely human carcinogen based upon studies of animals exposed to high levels of this chemical over their entire lifetimes.

At the level of 1,4-Dioxane detected in your water, exposure from drinking water and food preparation is well below 1,4-Dioxane exposures associated with health effects.

What is New York State doing about 1,4-Dioxane in public drinking water?
The New York State Department of Health (NYS DOH) has adopted a drinking water regulation that requires all public water systems to test for 1,4-Dioxane. If found above the MCLs, the water supplier must take steps to lower the level to meet the standard. Exceedances of the MCL signal that steps should be taken by the water system to reduce contaminant levels.

Where can I get more information?
