I grew up in the United States and have been drinking tap water my whole life. More recently some of my friends have been making me feel a little bit guilty or awkward about the safety of tap water, usually recommending me to use either use a water filter, or to boil my water. I think this is just hyperbole, but after a long time hearing this from different people, I am beginning to feel unsure.
I know some places in the United States and across the world have unsafe drinking water, but how do I know where the water is safe or not? Are there any certain tastes that are considered dangerous? Is it better for me to just start using filtered water?

It really depends on the location. Sciencemag.org has an article on this, which is backed up by this paper. To quote a relevant part from sciencemag:
The following sentence from the significance page from the scientific article's website leads me to the conclusion that you shouldn't be worried per se, but that it is certainly worth looking into the situation in your area:
If there is something wrong with the water (as you might find after your research) then see what the specific advice is. Some things may go away after boiling, others may not.
