Rising Salt Levels Threaten NYC’s Water

By Y.M. Lowy

Over the past 30 years, the amount of salt in one of New York City’s main water sources has tripled, and it’s on track to exceed safe levels by the turn of the next century. 

The Croton system, which provides 10% of the city’s water, has seen steadily rising salt levels partly due to road salt which the city puts before snow.

While New York City is known for its clean water, this increase in salinity is a growing concern. It not only affects water quality but also causes faster breakdown of pipes, increasing the risk of lead contamination. To address this, environmental officials are recommending less road salt before snowfall and improvements to wastewater plants.

Last year, the city planned to use more water from the Croton system to help with repairs on a major water line, but those plans were paused due to a drought. Repairs are now expected to continue later this year.
