Technical Report ·
OSTI ID:5267990
The Northwestern States Portland Cement site, a cement manufacturing facility, is in Mason City, Cerro Gordo County, Iowa. Calmus Creek flows between the Northwestern States Portland Cement Company (NWSPCC) facility and another cement manufacturing plant facility located just north of the site. The site includes a 150-acre area named the West Quarry where NWSPCC disposed of 2 million tons of waste cement kiln dust from 1969 to 1985. Local ground water and surface water have been impacted by elevated pH levels as a result of waste cement kiln dust disposal in the West Quarry. The Record of Decision addresses the contamination source, the cement kiln dust disposed of in the West Quarry, and the resulting ground water and surface water contamination. The primary contaminants of concern affecting the ground water and surface water are organics including phenols; metals including chromium and lead; and other inorganics including waste cement kiln dust.
