Garden City Park Water
Annual Water Quality Report

  Over the past eleven years, a full report on the annual test results has been published by the Garden City Park Water District. The full report for 2001 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.

DEFINITIONS

Maximum Contaminant Level MCL)- The highest level of a contaminant that is allowed in drining water. MCLs are set as close to the MCLGS as feasible.

Maximum Contaminant Level Goal (MCLG)- The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

Action Level (AL) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system much follow.

Milligrams per liter (mg/l) – Corresponds to one part of liquid in one million parts of liquid (parts per million – ppm).

Micrograms per liter (ug/l) – Corresponds to one part of liquid in one billion parts of liquid (parts per billion – ppb).

PCI/L Pico - Curies per Liter is a measure of radioactivity in water.

Non-Detects(ND) – Laboratory analysis indicates that the constituent is not present.

(1) - During 2005 we collected and analyzed 30 samples for lead and copper. The 90% percentile level is presented in the table. The action levels for both lead and copper were not exceeded at any site tested.

(2) - No MCL has been established for sodium. However, 20 mg/l is a recommended guideline for people on high restricted sodium diets and 270 mg/l for those on moderate sodium diets.

(3) - Perchlorate is not regulated by the USEPA. However, New York State has set an action level of 18.0 ppb.
