Never hesrd that. Bit I believe trust me if you lived in the town I do you wouldn't drink it pregnant or not! Couldn't even do my dishes the other c day bc water was **** yellow! Hit a letter v in the mail a couple weeks ago with the usual $100 water bill saying that sometimes out water may not be ok to drink! Then wth are we paying so much money for!? Something about how old and deep the well is ect. Frikin fix it!
My midwifes have told me the same thing. Its not good to drink tap water unless its been tested okay to drink. I just filter my water and have no problems
