former united zinc & associated smelters

HIGHWAY 54 & KANSAS DRIVE

The Former United Zinc and Associated Smelters Site is located in and around the city of Iola, Allen County, Kan. The main Former United Zinc facility is located on the east side of Iola within a mixture of residential and commercial properties. The site was one of several zinc and lead smelting operations in the area between 1902 and 1925. Residential and non-residential properties were contaminated with elevated levels of lead, arsenic, cadmium and zinc, which may be associated with historical lead and zinc smelting. The state of Kansas referred the site to EPA for Superfund removal action in September 2005. To date, EPA has sampled more than 1,600 of 3,400 properties for contamination. Of the more than 1,600 residential yards sampled, more than 500 had elevated levels of lead above 400 parts per million (ppm). EPA has excavated approximately 130 residential yards with lead levels above 800 ppm and replaced the contaminated soils with clean backfill soils followed by re-establishment of grass residential yards. These actions were conducted under the Superfund Time-Critical Removal Program.
