Is Merrick Tap Water Safe to Drink?

Can You Drink Tap Water in Merrick?

Yes, Merrick's tap water is generally considered safe to drink as Merrick has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page or the city's water provider website.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Merrick's water utility, New York American Water - Sea Cliff, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. This assessment is based on the New York American Water - Sea Cliff water system, other water systems in the city may have different results.

While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.

The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.

Merrick Tap Water Safe Drinking Water Act Violation History - Prior 10 Years

Below is a ten year history of violations for the water system named New York American Water - Sea Cliff for Merrick in New York. For more details please see the "What do these Violations Mean?" section below.

Is there Lead in Merrick Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Merrick water system, New York American Water - Sea Cliff, between sample start date and sample end date, were at or below, 0.0 mg/L of lead in Merrick water. This is 0% of the 0.015 mg/L action level. This means 10% of the samples taken from Merrick contained more lead.

While Merrick water testing may have found 0.0 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.

No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.

Are there PFAS in Merrick Tap Water?

Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be at least one military base - BETHPAGE NY NWIRP - near Merrick with suspected leaks.

With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Merrick has been evaluated for yet.

Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.
