The 71-acre Portland Cement site is located in Salt Lake City, Utah. Between 1963 and 1983, about 500,000 cubic yards of cement kiln dust (CKD) were collected from the Portland Cement Plant in Salt Lake City and deposited as fill material at the site. CKD contains several heavy metals, including arsenic, lead, chromium, cadmium and molybdenum. Additional waste disposal activities at the site included disposal of a few hundred tons of chromium-bearing bricks. These activities contaminated soil, air and groundwater with heavy metals. Following cleanup, operation and maintenance activities are ongoing.
