A water advisory has been issued again for vulnerable populations in the city of Salem and city of Turner.

The advisory was issued Wednesday morning after results from water quality samples indicated that levels of the cyanotoxins are at levels above the U.S. Environmental Protection Agency’s guidelines for children and vulnerable populations.

The advisory is for children under the age of 6 years old, people with compromised immune systems, people receiving dialysis treatment, people with pre-existing liver conditions, the elderly, pets, pregnant women or nursing mothers or other sensitive populations in the city of Salem, city of Turner, suburban East Salem Water District, and Orchard Heights Water Association.

People not listed above may continue to drink the water in the affected areas, according to city workers. Information will be updated at cityofsalem.net.

City officials said the earliest the latest advisory could be lifted is Friday.

People are also advised to not boil the tap water, as it will not destroy cyanotoxins and may actually increase the toxin levels.

Most water filters and purifiers will not remove this toxin from drinking water.

Free drinking water is available at multiple locations in the city of Salem: Wallace Marine Park, 200 Glen Creek Road NW, Salem Oregon State Fairgrounds, 2330 17th St. NE, Salem Bush’s Pasture Park, Mission Street entrance, 600 Mission St. SE, Salem Woodmansee Park, 4629 Sunnyside Road SE, Salem Chemeketa Community College, Brown Parking Lot, 4000 Lancaster Drive NE, Salem East Salem Suburban Water District, 3805 La Branch St. SE, Salem (Until 8 p.m.) City of Keizer Civic Center, 930 Chemawa Rd NE, Keizer Former Chevrolet Dealership, 5325 Denver Street, TurnerThe sites will operate around the clock, except East Salem Suburban Water District (open until 8 p.m.), until further notice. All bottled water distribution locations are pull-through, one case per vehicle for vulnerable populations.

People who need help can contact City of Salem Public Works at 503-588-6311.

This advisory comes after the city of Salem issued a water advisory on May 29 after low levels of cylindrospermopsin and microcystin were found in treated drinking water.

That advisory was lifted on June 2.
