Sea Cliff Water District

The Village of Sea Cliff's water supply is owned and controlled by a private company, currently Liberty Utilities.  The "Sea Cliff District" of Liberty includes Sea Cliff, Glen Head, Glenwood Landing and portions of Roslyn Harbor and Old Brookville.

The NYS DEC establishes water quality standards and other criteria for many specific substances. These standards can be either narrative (e.g., "none in amounts that will impair ...") or numeric (e.g., "0.001 µg/L") and are found in NYS regulation 6 NYCRR Part 703.  Additionally, The NYS Department of Health oversees the delivery of drinking water to ensure that it is suitable for people to drink. To assure the safety of drinking water the New York Department of Health, in cooperation with its partners in the county health departments, regulates the operation, design and quality of public water supplies.

NYS has recently adopted the most stringent standards for drinking water in the nation and these new standards take effect this spring.  Included in these standards are maximum contaminant levels, or MCLs, for three chemicals — 10 parts per trillion each for PFOA and PFOS, and an MCL of 1 part per billion for 1,4-Dioxane.
