Source of Water in Smithtown, United States

Tap water in Smithtown, New York, comes from groundwater beneath Suffolk County. Local public water suppliers, including the Smithtown Water District, pump water from wells drawing primarily from the Magothy aquifer.

The water is treated and disinfected before entering the distribution system. Because Long Island has no major surface-water supply for drinking water, Smithtown’s public water relies on underground aquifers replenished by rainfall.

Smithtown Drinking Fountains

Public drinking fountains in Smithtown are generally safe to use when they are connected to the municipal water system and properly maintained. That water is regulated under New York State and federal drinking-water standards.
