Technical Report · Fri Dec 27 04:00:00 EST 1991

OSTI ID:5704049

The Northwestern States Portland Cement Company (NWSPCC) NPL site is situated in the northern section of Mason City, Cerro Gordo County, Iowa. The major concern at the site is contaminated surface water and ground water as a result of contact with waste cement kiln dust in the West Quarry. On-site surface water and ground water are contaminated with lead, sodium, sulfates, and reflects high pH. The waste kiln dust is in contact with both the surficial and Devonian aquifers on site; hence, there is a potential for contamination of the Devonian aquifer off-site. Potential exposure pathways of concern include ingestion of contaminated ground water; accidental ingestion and dermal contact with contaminated surface water, and accidental ingestion and dermal contact with contaminated soils and sediment; and inhalation of entrained dust. Under current conditions the NWSPCC NPL site poses no apparent public health hazard. However, potential risk to human health resulting from possible exposure to on-site and off-site hazardous substances exists in the future if the site is not remediated. The site is currently under remediation to mitigate the potential risk.
