Note: the chart above indicates 1,4-dioxane levels in water supplied by public water suppliers. Information regarding water supplied by New York American Water (NYAW), the private company that supplies water to a large area in which many of our local League members live, is rarely included in public reports. As a resident of one of these areas, I contacted the water company and was told that only one of their wells had a detectable level of 1,4-dioxane, and that well was closed. I hope I was given correct information.
You can see on the chart on page 4 that many common household products contain 1,4-dioxane, and it is continually being washed down the drain. However, most of the 1,4-dioxane in the aquifer from which our water is pumped entered years ago from industrial use as a solvent. Also, since Nassau County is mostly sewered, any of the material in products we might be using now will end up in the ocean, not the aquifer system. (That’s not good for our environment either!!!)
