Pleasant Grove, Utah • A Utah County pool is set to re-open more than a week after an accident sickened dozens with chlorine gas.

The Daily Herald reports the Pleasant Grove Veterans Memorial Pool is expected to welcome swimmers back on Thursday.

About 50 people were sickened June 4 after a pump forced too much chlorine out of a jet. Police say they were coughing, vomiting and bleeding from their noses.

Ambulances took about 26 people to hospitals and about two dozen others sought treatment themselves.

City officials say they’re installing a new chlorine-distributing control box with built-in safeguards to prevent a similar accident.
