Blue or Blue-Green Discoloration

Most Common Cause In homes with copper pipes, leaching can occur most commonly when electrical appliances are improperly grounded to household plumbing pipes.

Recommended Action: If the home has improper grounding of appliance(s), please contact an electrical expert.


Common Cause: The natural color of water is very light blue; however the most common cause for darker shades of blue is water back-siphonage, typically from a toilet tank containing blue disinfectant tablets. Back-siphonage is a separate issue that must be addressed by a plumbing expert; however, without testing, the exact cause of the blue/blue-green discoloration cannot be confirmed. 

Recommended Action: Please stop consuming (drinking, cooking, etc.) water immediately and call Citizens at 317-927-4334.


After taking the above listed actions, if the concern was not resolved, please open a case to be contacted by a Customer Case Manager.
