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

The problem was reported in January 2008 when construction crews began work on the new airport tower, requiring 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 excavation was limited because of electrical conduits and storm drain pipes. 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 eventually removed by Standard Oil in the mid-1970s.
