Anaheim responds: city water not at issue in Children’s Dental outbreak

Water Quality

ANAHEIM, Calif. (April 12, 2017) — For more than a century, the city of Anaheim has provided safe, reliable and high-quality water to residents, businesses and visitors.

We want to be clear: Anaheim’s water supply is not at issue in the case of Children’s Dental.

Children’s Dental is an Anaheim dental clinic twice shut down by county healthcare regulators in 2016 after about 70 young patients were treated for bacterial infections after visiting the clinic.

“Our hearts go out to the kids and families who visited Children’s Dental,” city spokesman Mike Lyster said. “No one should have to go through what they have. But we have no reason to doubt the OC Health Care Agency’s determination that the likely source of infection was the internal dental water system.”

Here’s why we are confident in Anaheim’s water and you can be too:

  • Anaheim conducts 44,000 tests each year to ensure safety and quality.
  • Each week, we test our water at 51 sampling sites across the city, including two near the now-closed Children’s Dental location.
  • None of our testing, either before or after Children’s Dental came to light, has indicated an issue with bacteria in water delivered to the site.
  • We test for more than 100 possible substances, including an indicator of bacteria that would have detected the mycobacteria at issue in the Children’s Dental case.
  • We thoroughly treat and test our water to ensure that it meets or exceeds state and federal safety standards for drinking and uses such as dentistry.

The best thing parents or any dental patient can do is to make sure their dentist follows recommendations for water quality from the Centers for Disease Control and the American Dental Association.

“I drink Anaheim water every day at work,” Lyster said. “No one should have any concerns about Anaheim’s water.”
