Bottled water is readily available. I have used the tap water to brush my teeth, take a pill, cook with, and even used it with ice (made from the same water) to make tea. No problems, but since she's pregnant, why tempt fate? Get bottled water and enjoy..and drink a lot of it. I suggest getting a five gallon bottle and use it to fill cups/bottles, and not add to the plastic pollution if you can help it. You can get big bottles, or if need be, one gallon bottles almost everywhere. We go through a five gallon bottle every 3 days or so, using it only to drink. Need to keep hydrated, ya know.
