Discolored well water has prompted the state to provide bottled water to staff members and residents at the Rainier School in Buckley, the Department of Social and Health Services said Friday.
Preliminary tests indicate the discoloration might be caused by manganese, a metal found in many types of rocks, DSHS said.
While manganese is not harmful to human health, the state will provide bottled water at the school until further testing is complete.
“We are being over-protective in this instance,” said Evelyn Perez, assistant secretary with the Developmental Disabilities Administration.
The Rainier School is a home for people with developmental disabilities.
