Groundwater testing at Ithaca Gun has identified the presence of TCE above the standard established by the state Department of Environmental Conservation.

Samples were taken from three groundwater monitoring wells on the property in November 2007, said Mary Jane Peachey, a DEC engineer. Two of the three samples registered trichloroethylene, or TCE, readings above the state's groundwater standard of 5 parts per billion: one location between the factory and the smokestack was 152 ppb; one location near the smokestack was 98 ppb.

“The groundwater in this particular case is being monitored at a location 50 feet into rock. So exposure is not something occurring here on this site. That's a good thing,” Peachey said. “What this tells us is that there is a need to do a complete investigation up on the site itself.”
