LACEY TOWNSHIP, N.J. - New Jersey's Department of Environmental Protection is telling the owners of the Oyster Creek nuclear-power plant exactly where to look for evidence of contaminated groundwater that leaked from the aging facility.

The DEP wants Exelon Corp. to drill eight testing wells in the Cohansey Aquifer, a major source of drinking water for South Jersey. Commissioner Bob Martin said Exelon was moving quickly to comply.

Earlier this year, the state said radioactive tritium that leaked from pipes at the plant had reached the underground water source, though it stresses that no drinking water in homes or businesses had been tainted yet.

The Lacey Township facility is the nation's oldest nuclear power plant. It opened in 1969.
