Most municipal tap water in our area is safe for formula, and pediatric guidance generally allows it. The two things worth paying attention to are lead from older home plumbing and fluoride levels if formula is a baby's only source.
If your home was built before 1986 and may have lead solder or fittings, run the cold tap for a minute first and never mix formula with hot tap water, which pulls more metal out of the pipes.
On well water, testing is not optional. Nitrates and bacteria matter enormously for infants, and a lab test is the only way to know.
A reverse osmosis system at the kitchen sink is the most reliable at-home answer. We install and service them, and we test your water first so the system matches the actual problem.
