Problems We Found In New York City Water

 Kezia Snipe | Hydroviv Research Analyst


For Hydroviv’s assessment of New York City tap water, we aggregated water quality test data from New York City Environmental Protection, the water provider for America’s largest city, and the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze.  We cross reference these data with toxicity studies in scientific and medical literature, and look at upcoming regulatory changes.  The water filters that Hydroviv offers are optimized with these numbers in mind.

Source Of New York City Drinking Water

New York City gets its drinking water from a surface supply system that comprises 19 reservoirs and three controlled lakes spread across a nearly 2,000-square-mile watershed. The watershed is roughly the size of the State of Delaware, extending 125 miles north and west of New York City. The New York City Water Supply System, consists of three individual water supplies: the Catskill/Delaware supply, located in Delaware, Greene, Schoharie, Sullivan, and Ulster counties; the Croton supply, New York City’s original upstate supply, in Putnam, Westchester, and Dutchess counties; and a groundwater supply in southeastern Queens.

Lead In New York City Drinking Water

Lead enters tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels.  Currently, 10% of samples analyzed for lead in New York City are 11 parts per billion. Though the city is currently in compliance with federal regulations, the EPA and CDC have both acknowledged that there is no safe level of lead, and federal regulations do not take into account levels measured at an individual tap.  The American Academy of Pediatrics recommends that any taps used to serve children have lead levels no higher than 1 part per billion. 

Chromium 6 In New York City Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, New York City tap water has averaged 45 parts per trillion for Chromium 6. For the sake of perspective, these levels are 2.25 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In New York City Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter.  Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.
