In 2016, the Anacortes Water Treatment Plant participated in a voluntary survey conducted by the Washington State Department of Health's Office of Drinking Water.
The online survey requested information on the existence, or non existence, of lead service lines and lead components in federally regulated public water systems in the state.
DOH's survey stemmed from a directive from Gov. Jay Inslee in response to increased public concern about lead in drinking water. Inslee directed state agencies to address potential sources of lead exposure and identify ways to minimize exposure to lead.
