The 58-acre Greenacres Landfill site is located near Liberty Lake, about 14 miles east of Spokane, Washington. Between 1951 and 1972, the site owner operated a landfill on site. The landfill accepted household, industrial and agricultural wastes. Site activities contaminated groundwater with volatile organic compounds (VOCs), semi-volatile organics and heavy metals. Following cleanup, operation and maintenance activities and monitoring are ongoing.
