Contaminated soil at the site of the new traffic control tower at the Medford airport has been cleaned up, the Oregon Department of Environmental Quality has determined.

The problem, reported in January 2008 when construction workers began work on the new airport tower, required the removal of 2,625 tons of petroleum-contaminated soil.

The soil was treated and reused on airport property with the approval of DEQ. A small amount of soil remains in the southeast corner of 661 Airport Road, but electrical conduits and storm drain pipes limited excavation. The DEQ considers the level of contamination safe. No groundwater problems have been detected.

The property was used as a fueling station from the 1960s through the 1970s. Fuel was stored in several underground tanks, which were removed by Standard Oil in the mid-1970s.
