Yes, NYC tap water is safe to drink for most people, and the source water is genuinely among the best of any large American city. The part that varies is your building: lead can come from a service line laid before 1961, lead solder from before 1987 and brass faucets, and in 2025 16 of the 326 homes the city tested were over 15 ppb. Here is what the city's 2025 water report shows, how to get the city's free lead test, what our $199 city water test adds, and which filter fits NYC water.
Yes. Las Vegas tap water meets every federal health standard, and every 2025 result the EPA judges the district on was under its limit. What you notice is the hard water, about 16 grains per gallon, and the chlorine taste. Here is what the Water District's 2026 report shows, who serves Henderson and North Las Vegas, the hotel answer, what our $199 city water test checks, and which filter fits a Las Vegas house.
Yes, Los Angeles tap water is safe to drink by both federal and California standards. I went through LADWP's 2025 report: every regulated substance met its legal limit, and no lead service lines exist anywhere in the LADWP system. What you may notice is hard water, from about 6 grains per gallon on the west side to nearly 14 in Eastern LA and the Harbor, and the chlorine taste of chloramine. Here are the 2025 numbers by neighborhood, what the city cannot test for you, and the filter I would put in, if any.
