Emerging Contaminant Project Information

The Water Authority has an active project to address emerging contaminants, including perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), and 1,4-Dioxane

You can view our Frequently Asked Questions page on 1,4-Dioxane here.

In early 2021 a letter was sent to all customers regarding a deferral issued for PFOA, PFOS and 1,4-Dioxane. Below we will provide updates as we continue to work on the project to treat for these chemicals.
