SALEM, Ore. — The Salem public works department is taking extra steps to filter out a toxin produced by an algae bloom in the North Santiam River, the city's primary source of water.

Barely measurable amounts of the toxin, cylindrospermopsin, were found Aug. 1 in samples.

The Statesman Journal reports no toxin has been found in Salem's finished drinking water.

The extra water treatment processes will continue until no trace of the toxin is found in river water.

The toxin could cause nausea. It's a different toxin from the one that recently contaminated water in Toledo, Ohio.
