Dive right in — the water’s fine.
The Post gathered samples from seven city pools — and a lab analysis found all of them to be shockingly clean.
Four private and three public pools were tested: Dream Downtown in Manhattan, Hampton Inn & Suites in Staten Island, McCarren Park Pool and McCarren Hotel & Pool in Brooklyn, Astoria Sports Complex and Astoria Park Pool in Queens, and Crotona Outdoor Olympic Pool in the Bronx.
None had coliform bacteria, which indicates a presence of pathogens such as E.coli. The latter can cause bloody diarrhea, nausea and abdominal cramping.
Sam Biederman, an assistant commissioner for communication at NYC Parks, says that their pools are tested for contamination every hour.
“Cooling off at an NYC Parks pool is part of a New York City summer — and that’s why we are always working to keep our pools safe and clean,” Biederman tells The Post.
The results are a stark contrast to a CDC report released in 2013, which found that nearly 58 percent of public pools nationwide tested positive for E. coli, a bacteria normally found in human feces.
Another CDC report released this spring found that about 80 percent of public pools in the U.S. had at least one health and safety violation inspection. Common flubs included poor safety equipment, as well as too little disinfectant concentrate and abnormal pH levels, which can make swimmers prone to infections.
The CDC recommends that a pool has at least one ppm of chlorine and three ppm of bromine, which keeps germs at bay. To maximize the disinfectants’ effectiveness, a pool’s pH value should be between 7.2 and 7.8. If the water fluctuates beyond these levels, germs are more likely to spread.
Your best bet is to ask experts: “Ask for recent inspection scores at your pool. If they don’t have them there, you can find scores for public pools on the health department web site,” says Brittany Behm, a spokesperson for the CDC.
You can also buy your own test trips — $10 for a pack of 50 or more — and test pH, chlorine and bromine levels yourself.
