Risk from home tap water?

I have been living in house for over four months with a hot water heater that is not the proper temperature. My landlord will not get a water heater mixing valve. I am very concerned about Legionella. I have been very sick for months with nausea and diarrhea.

I worry because I am eight months pregnant and I also have a ten month old. I drink this water every day and also use it for my son’s formula bottles. What should I do, and how much danger are we in?

The danger of Legionella infection from your drinking water is negligible unless your are a cigarette smoker or have an immunosuppresive condition (transplant recipient, cancer chemotherapy, etc).

The danger for your baby is also negligible; however, since you are making formula, merely use water that has been pre-boiled.
