If all is good, then the consumer confidence report will let you know. You can also talk to the water folks to find out what is being done to fix any issue’s in the city’ water lines.
  • If your city water has a good consumer confidence report, you can surely use it to prepare infant formula or thin out the baby food. Even if your city water is perfectly fine, you can still get your water tested to know if any contaminants may be coming from the pipes into your household.
  • If you use well water then you won’t have a consumer confidence report; instead, you’ll have to get the water tested yourself. With a baby in the house, you will have to make sure that your well water does not have nitrates in them.
