Safe & Clean Water

From the Anacortes Water Treatment Plant

The Anacortes Water Treatment Plant has been supplying its customers with safe and superior quality drinking water for over 91 years. In 2013, Anacortes completed a new, state-of-the-art water treatment plant to meet increased demand.

While conducting a demolition assessment of the old Anacortes Water Treatment Plant, samples of building materials and soil found PCBs— all common compounds for 1970s era buildings.  The levels exceed applicable regulatory standards but do not pose a threat to drinking water.

Public Works officials immediately reviewed all water sample records and determined there was no threat to public health and the water was safe. A further human health risk assessment by independent experts confirmed the water was safe and no adverse health effects are likely to have occurred to customers, workers, or water plant visitors as a result of PCBs at the former plant.

The City of Anacortes, with oversight from the Washington State Department of Ecology, has completed two reports: the Remedial Investigation (RI) and Feasibility Study (FS). These reports describe the nature and extent of the contamination found at the site, evaluate cleanup alternatives, and identify a preferred cleanup alternative.

We are committed to the safe demolition of the old water treatment plant. In the FS, we have proposed a cleanup alternative that addresses Site contamination in the most protective and permanent manner to ensure the safety of our drinking water and to protect public health and the environment.

The Department of Ecology supports this cleanup alternative and is currently accepting public comment on the RI and FS documents. The agency held an online-only public meeting on March 23, 2020 to provide an overview of the RI and FS studies and answer questions from the public.
