Radioactive material ended up discovered in a monitoring well at Peach Bottom Atomic Power Plant, located along the Susquehanna River in Pennsylvania.
They have been monitoring the leak closely since April, said company spokeswoman Krista Merkel. Merkel said the leak has not affected business, drinking water or the river. Peach Bottom officials have not released a cause of the leak at this time.
Exelon, Peach Bottom’s parent company, found tritium levels as high as 37,700 picocuries per liter in the monitoring well. That is above the 20,000 picocuries per liter limit set by the U.S. Environmental Protection Agency. Tritium is a radioactive isotope of hydrogen.
“More recent tests have shown tritium levels have returned to previous values,” according to a Peach Bottom statement. “Both state and federal regulatory officials were notified and are periodically updated on the monitoring program.”
Merkel said they will continue to monitor the situation closely.
Peach Bottom Atomic Power Station is 50 miles southeast of Harrisburg in Peach Bottom Township, York County, PA, on the Susquehanna River three miles north of the Maryland border.
