Legionella Risk Management for the Hospitality & Casino Industries

Now more than ever, hotels and casinos are held to a high standard with keeping their guests, staff and communities safe. Among the many vulnerable areas on-property, one potentially overlooked risk can come in the form of Legionella bacteria. If not managed properly, a Legionellosis outbreak can occur on a scale of anywhere from a couple of guests to more widespread cases in the surrounding community.

Nalco Water is a global leader in Legionella risk management in the Hospitality and Casino industries. We’re uniquely qualified to help properties manage the risk from the cooling tower to the guest room.
