POLAND, Maine — Authorities are trying to determine what caused an ammonia leak at the Poland Spring bottling plant in Poland, Maine.
Nestle Waters North American said the plant had to be evacuated on Thursday because of the leak and that two employees who complained of headaches were taken to the hospital. Both employees have been released from the hospital.
The company says that its bottled water currently in the marketplace is unaffected and safe to drink.
Nestle says that the leak is no longer active and that employees are being allowed to re-enter the facility. It's working with the Poland Fire Department and others officials to pinpoint the cause of the leak.
Ammonia, which is commonly used in refrigeration, can cause burns. It can also be fatal if inhaled.
