When looking through travel guides and websites, I often see the statement that tap water is not safe in Nicaragua. For example, the US State Department says:
Tap water is not considered safe in Nicaragua. All persons should drink only bottled water.
Expats living in Nicaragua have told me that travelers should only drink bottled water, but only because it's common to get Traveler's Diarrhea (TD) from the water, not because it's dangerous. In fact, they mentioned that it is so highly chlorinated that it's probably very safe (other than the standard results of drinking tap water in a foreign country).
Is tap water in Nicaragua actually dangerous to drink for reasons other than TD, or is that what the various advisories mean when they say it is "not considered safe"?
