> New York City’s water (including drinking water) is unfiltered, making it the largest unfiltered water system in the country. Were New York to begin filtering its water, it would cost the city approximately 1 million dollars per day to operate the filtration plant.
They have hundreds of sampling stations to check daily.

This causes some issues for observant Jews, because the water technically might not be kosher.

- andrewflnr 8mo agoOk, but unfiltered does not imply untreated. Maybe that's where they got the idea, though.
- devilbunny 8mo agoIt is, indeed. I'd edit the post but... too late.
- valarauko 8mo agoIt's largely unfiltered, but it is still treated for disinfection. Chlorination and UV is standard for NYC water, and its fluoridated as well.
- markdown 8mo agoTreatment is usually just the addition of chlorine and in some countries, fluoride. Filtration isn't common.
- devilbunny 8mo agoSettlement, however, is fairly standard in surface supply.
