Effective June 1, 2020, Nantucket will enforce a ban on single-use plastics including bottled water. Bottled water will no longer be sold in sizes smaller than one liter (34 ounces) in island groceries, delis, and cafes. Nantucket is implementing these pro-active measures to support your use of your own water bottle around town, on the bike paths, and at the beaches; Nantucket's tap water is safe, reliable and tastes great! Wannacomet Water Company
produces an annual water quality report to document the cleanliness and safety of Nantucket's public water supply.
