The Chemplex facility in Clinton County, Iowa, was constructed in 1967 and has been in operation since then. Equistar Chemicals, LP, is the current operator. The facility manufactures high- and low-density polyethylene plastics from chemical stock.

Due to past waste disposal practices, ground water and soil at the Chemplex Site were contaminated with volatile organic compounds (VOCs) and polynuclear aromatic hydrocarbons (PAHs). EPA divided cleanup activities at the Site into two phases, called operable units.

Operable Unit 1 (OU1) addressed ground water on a Site-wide basis and OU2 addressed contaminated soils and wastes which were sources of ground water contamination.


EPA encourages the community to review the Administrative Record which contains information about past cleanup activities and next steps. The Administrative Record is available during normal business hours at the following locations:
