American Water Works — a supplier of drinking water and wastewater services to more than 14 million people — on Monday said hackers had breached its computer networks and systems, prompting it to pause billing to customers.

The Camden, New Jersey-based utility became aware of the unauthorized activity on Thursday, and took protective steps, including shutting down certain systems, American Water Works stated in a regulatory filing. The company does not believe its facilities or operations were impacted by the cybersecurity incident, but is “currently unable to predict the full impact,” it stated.

The company said it had notified law enforcement and is cooperating with them.

According to its website, American Water is the largest regulated water and wastewater utility company in the U.S., and provides drinking water and wastewater services to more than 14 million people in 14 states and on 18 military installations. It manages more than 500 water and wastewater systems in about 1,700 communities in California, Georgia, Hawaii, Illinois, Indiana, Iowa, Kentucky, Maryland, Missouri, New Jersey, Pennsylvania, Tennessee, Virginia and West Virginia.
