Our city water was found to have very large amounts of Uranium in it, the city officials…

This is a fabulous question! Unfortunately, none of us know the health effects of drinking water with above "normal" uranium levels in our pets. The effects are sometimes studied in wildlife but to my knowledge no studies have been done in our pets. To be as safe as possible, I would not allow your pets to drink the water if you have been advised not to. If your pets have or develop any health issues, I would share this uranium level information with your veterinarian. This issue may have surfaced recently as the Environmental Protection agency has changed their regulations on what is considered a safe uranium level in water. Even at just above normal uranium levels, drinking water at this level daily is considered by officials comparable to getting an x-ray taken once a year. An x-ray once a year is relatively safe for your pets but again to be safe it will not hurt to continue to use filtered water. For more information, your local veterinarian may be able to help you or you could talk to your local EPA office or water provider.
