Keeping hydrated while pregnant is extremely important, and it's necessary for ladies carrying babies to drink at least eight glasses a day. However, many women in the USofA don't have access to filtered water, and instead drink straight from their kitchen sink. Pretty harmless, right? Yeah, not so much.

A new study published in the Canadian Journal of Economics from Princeton University links tap water to a higher risk of birth defects. Researchers found that over a quarter of observed New Jersey districts had contaminated water, affecting more than 30,000 people. Pregnant women living in these areas who were exposed to the polluted water were more likely to experience birth complications, including low birth weight and premature deliveries.

Before you completely freak out and stock up on bottled H2O, keep in mind that the study doesn't concretely prove that tap water causes birth complications — just that there's an association between the two. However, it goes without saying that pregnant women should research whether the water coming out of their sink is safe to drink, and if not a filter system could be a good idea!

Will you think twice before drinking the water from your kitchen, or do you think there's nothing to worry about? Tell us what you think about this alarming new study in the comments!
