Investigators and a radiation specialist visited Indian Point on Thursday to inspect a water leak at the nuclear power plant.

Radioactive tritium-contaminated water leaked into the ground water at three of the monitoring wells last week.

According to Entergy, the company that owns the plant, the wells are not for drinking so there is no threat to the public. It also said that the leaked levels were one-tenth of one percent of what is required to be reported, but it wanted to voluntarily report the information to the Nuclear Regulatory Commission.

It believes the leak occurred during the process of drawing water out of a tank to filter it.

Gov. Andrew Cuomo has called for a full investigation of Indian Point because there have been similar incidents that state and local leaders say have raised red flags about whether or not the plant should continue to operate.

Entergy said contaminated water did leak into the Hudson River, but it was not at detectable levels.

A report is scheduled to be released within 45 days by the NRC.
