Exelon: No public threat from tritium leak

A tritium leak was found during routine monitoring of Exelon Corp.'s nuclear power plant, but contaminated water was contained to the property and did not pose a public health threat, company officials said Monday.

Testing at the Dresden plant, near the town of Morris about 60 miles southwest of Chicago, found tritium levels of 3.2 million picocuries per liter of water in a monitoring well, storm drains and concrete vault. The U.S. Environmental Protection Agency's limit for drinking water is 20,000 picocuries per liter.

But there was no public safety threat because the contaminated water did not appear to have left the plant, officials said in a written statement.
