Check your water
Municipally treated water, in general, is very safe; in fact, many bottled waters that seem extra pure are just municipal tap water. For extra protection, or if you don’t like the taste from the tap, look for NFS-certified home water filters.
If your water comes from a well, make sure you have your water tested at least annually to make sure it’s free of harmful bacteria, viruses, and chemicals. If necessary, choose a water filtration system based on the test results.
