EPA Sampling Results announced for Macon Naval Ordnance Plant Superfund site in Macon, Ga.


ATLANTA – Today, the U.S. Environmental Protection Agency (EPA) announced the status of its vapor intrusion sampling conducted at the Macon Naval Ordnance Plant Superfund site in Macon, Ga. Funded by EPA, the sampling focused on the Freudenberg Texbond facility, located down gradient of the Navy’s former wastewater treatment plant. During the week of February 23, 2015, EPA activities included:

·	Fourteen indoor air samples at various locations were collected over a 24-hour period, with an emphasis on smaller enclosed areas where trichloroethylene (TCE) might accumulate (e.g., break rooms, laboratories, and offices). Outdoor air, sub-slab soil gas, and groundwater samples were also collected.

·	Thirteen of the fourteen indoor air samples did not indicate an unacceptable risk, with only trace detections of various volatile organic compounds found.

·	TCE was detected at a level of 230 µg/m3 (micrograms per cubic meter of air) in indoor air collected in the employee break room of the Line 7 Building. This TCE level exceeds EPA’s levels of concern of 9-27 µg/m3 for a commercial use, assuming an 8 hour per day occupancy.
