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.Updated information for this deferral will be sent to customers in the fall of 2022 - this information is available below.
