It’s been called “the champagne of tap water.”

The H2O coming through New York City’s pipes is so clean, in fact, that NYC is one of the only major US cities that doesn’t use filtration.

If you get your hydration right from the tap, you know it just tastes good — and it’s been said it’s at least partly responsible for why our bagels are superior.

So when Culligan gave us the chance to try out their at-home water testing kit — which looks for contaminants like lead, copper and arsenic as well as forever chemicals — we jumped at the chance to find out for ourselves: How healthy is New York City’s tap water, really?

Collecting the samples at my Manhattan apartment was was super easy — though it was actually for two tests, one covering contaminants and another that looks for PFAS, also known as “forever chemicals.”

Earlier this year, a study found that 97 million Americans are exposed to these forever chemicals through their tap water.

PFAS have been linked to a bunch of health concerns including reproductive issues, an increased risk of cancer, reduced immunity, higher cholesterol, higher obesity risk and developmental effects in children.

And the bad news? New Yorkers aren’t totally shielded while sipping our on-tap champagne.

“We identified one compound: PFBA, which stands for Perfluorobutanoic acid,” Culligan’s lab manager Maria Mozdzen explained, going over our test results. “We found that to be at 2.2 parts per trillion.”

That’s higher than EWG [Environmental Working Group]’s health guidelines, which are set at one part per trillion. The EPA doesn’t yet set limits on PFAS in water.

So how bad are these results, really?

It turns out… not that bad at all. Culligan had tested for 55 PFAS compounds.

So how bad are these results, really?

“I think your municipality is doing a great job,” Mozdzen said.

Though PFBA was identified, it was “very lower level” in the sample tested. Mozdzen noted that I may still want to address it — like with a PFAS filtration system — depending on my comfort level.

“If this was me or my household, I would definitely want to protect myself from it,” she said.

Forever chemicals can also be found in a load of other products we use, from cookware to makeup. Scientists have been on the hunt for ways to limit our exposure — even if it’s bit by bit.

It’s important to note, though, that this test captured a single point in time — and what’s found in the water can change slightly throughout the year.

Dr. Eric Roy, Culligan’s Head of Science, said that New York City does a “really good job” of conducting different types of tests, so their results have shown variability.

They have found, at times, the presence of another forever chemical that wasn’t in my sample, PFOA. (That was also only at about 2.1 parts per trillion — so higher than the EWG recommends, but not particularly high.) If I were to test again in a few months, I might have a different result.
