Ever since I became pregnant I have been drinking bottled water because I’ve heard that drinking tap water during pregnancy is unhealthy. Is that true?
Some studies have found that the chlorine used to treat public water can turn into chloroform when it mixes with other materials in the water, which may increase the risk of miscarriage and poor fetal growth. But it's important to note that other studies have found no such links. Also of concern to some is the potential for the water to be contaminated by things like lead and pesticides.
If you're concerned, contact your local water supplier to get a copy of the annual water quality report. If you have well water, you should probably have it checked about once a year by a state-certified laboratory whether you're pregnant or not. You could also buy a water filtration system to help reduce lead levels, some bacteria and viruses, and chemicals such as chlorine. But read the product's label thoroughly since some do more than others.
