Garden City Park Water
Annual Water Quality Report

  Over the past several years, a full report on the annual test results has been published by the Garden City Park Water District. The full report for 2010 is included in this newsletter.
  Each year, every water district is required to provide a comprehensive report on the quality of the water delivered to its customers.
  Your District routinely monitors drinking water quality. Each of our wells is tested before distribution. All test results are reviewed by the Department of Health and must be within State and County limits or water cannot be distributed to the public.
  Again this year the Garden City Park Water District is pleased to report that the water supplied to the community meets all the standards required by the U.S. Environmental Protection Agency, the New York Department of Health, and the Nassau County Department of Health.
