Removing 1,4 Dioxane at Residential Level RE: Long Island
Published on by Komal Saini, Water, Sanitation, & Hygiene Engineer, Seeking Roles in International Development & Research in Technology
1,4 dioxane, identified by the EPA as a "likely human carcinogen", has been found in extremely high levels in the Long Island area. (Please see http://www.nswcawater.org/facts-about-14-dioxane/ for reference).
Currently, there are no certified residential-level treatment technologies available to remove 1,4 dioxane from water supply.
Based on the preliminary research I've done so far:
- 1,4 dioxane removal is only only available/safe at the industrial level, where WTPs are mainly using UV + hydrogen peroxide or ozone technologies
- Granulated Activated Carbon filters and UV lamps safely installed at the supply point for households, has a removal rate >50%
- Boiling water with 1,4 dioxane may increase the concentration of the chemical
- Installing ozone technologies at the household level are still not deemed safe
My question to the experts in our community:
What are the safest & most effective technology options for removing 1,4 dioxane at the household level?
I am asking on behalf of the families (including my own) who are relying on bottled water as their drinking water source.
