Water Treatment Chemicals and Services - Iowa Medical Classification CenterThe contract spans one year from August 1, 2026, to July 31, 2027, with an option for mutual renewal up to five additional years. It seeks a vendor to deliver comprehensive chemical treatment and maintenance services for the steam and chilled water systems at the Iowa Medical Classification Center, ensuring optimal operational efficiency, corrosion prevention, and environmental compliance.
