The nuclear power plant is only 40 miles from Central Park, and even closer to Danbury and Greenwich, Connecticut.
New York City and Westchester County both get power from the Indian Point nuclear plant on the banks of the Hudson River. But the plant's age, and a series of problems at the facility, have led to questions about its future.
Last month, several monitoring wells showed an increase in radioactivity due to the leak of tritium into the water.
The nuclear power plant is only 40 miles from Central Park, and even closer to Danbury and Greenwich, Connecticut.
New York Governor Andrew Cuomo has renewed his call for the plant's closure after the most recent incident.
Scott Waldman, POLITICO New York's reporter on energy and the environment, told WNPR's Where We Live that the debate over Indian Point has been an ongoing battle for years.
"Environmental groups have wanted to plant shut down for a long time and they have a host of reasons," said Waldman, adding that people living near the plant are concerned, too. "Also, you have folks that are pleased that the amount of power it generates is quite significant for New York City."
There have been a series of issues, including transformer fires in the past. But Entergy spokesman Mike Twomey said the company has invested over a billion dollars to make the power plant safe.
"We've essentially replaced or repaired or upgraded all of the major components in the plant over the last 15 years," said Twomey.
State officials said the latest leak is not an immediate health risk to nearby residents.
