SALEM, Ore. (AP) -- A drinking water advisory for vulnerable populations has been lifted in and around the Oregon state capital area.
The Statesman Journal reports that tests show Salem's drinking water has tested below Environmental Protection Agency health advisory levels for toxins for the past 12 days.
The advisory was for children under 6 years old, people with compromised immune systems or those who were pregnant or breastfeeding.
The first advisory was issued May 29, three days after the city learned toxins linked to an algae bloom were detected in Salem's drinking water. That initial alert was lifted June 2, only for another one to be issued June 6.
On June 10, city officials extended the advisory during which time scientists and engineers developed a new treatment technique and added a system that allows water test results to come back the same day testing is done.
