New York City drinking water is world-renowned for its quality. Each day, more than one billion gallons of fresh, clean water is delivered from large upstate reservoirs to the taps of nine million customers throughout New York. New York City’s pristine drinking water “is supposed to be some of the best in the country,” says Occupational Medicine Specialist Marc Wilkenfeld, M.D., Director of the Division of Occupational and Environmental Medicine at Winthrop University Hospital in Mineola, NY. The water is transported over 100 miles and is routinely tested for bacteria. The main issue with New York City's tap water is the old pipes used to transport the water. “Lead is the most common reason that you run into a water problem in New York,” says Dr. Wilkenfeld. He suggests running your water for 30 seconds and / or purchasing a faucet water filter.
