WHITE PLAINS – Mount Vernon’s water was voted the best tasting in Westchester County at the annual tap water competition in downtown White Plains.
The “sip-off” allowed spectators to sample and rate water samples without knowing which area of the county each sample came from.
Mount Vernon received 28 votes from testers. The runner-up was Briarcliff Manor with 14 votes.
Additionally, the Annual Water Quality Report for the City of Mount Vernon is available here. Interested parties can find the archive of Water Quality Reports going back to 2003.
