About this file
This file is an informational document from the Iowa Management and Contracts System (IMPACS) platform, featuring instructions for accessing and responding to state procurement opportunities through the Jaggaer ONE platform. The document serves as a general portal guide rather than a specific solicitation file and does not contain detailed information about the Lake of Three Fires alum application project. However, based on the related contract opportunity summary provided, the Iowa Department of Natural Resources issued Request for Quote 26CRDLWBBDODD-0003 for alum applications at Lake of Three Fires, Green Valley Lake, and Prairie Rose Lake. The project encompasses chemical treatments totaling 92.8 acres across three lake restoration sites, with applications scheduled for spring treatments from April 1–May 1, 2026, and fall treatments for Lake of Three Fires between September 8 and November 13, 2026. Quotes were due on October 1, 2025, at 11:00 AM, with an anticipated contract execution date of November 13, 2025. The contract term runs from January 1, 2026, through December 31, 2026, with the possibility of one annual extension.
The project involves the application of aluminum sulfate and sodium aluminate to reduce phosphorus concentrations and mitigate internal phosphorus recycling, with chemical quantities including 71,516 gallons for Lake of Three Fires and varying amounts for the other lakes. Contractors are responsible for providing equipment, conducting chemical applications, managing site access and staging, installing signage, and restoring sites following treatment, along with monitoring pH levels and maintaining detailed daily records. The solicitation requires bidders to submit comprehensive documentation including contact details, contractor registration, years in business, technical experience, key personnel resumes, and three professional references. The DNR allows a 60-day invoice payment period in accordance with Iowa Code, with payments made in US Dollars. No specific set-aside designations for disadvantaged enterprises were explicitly outlined in the solicitation, and the project builds upon previous research conducted by Iowa State University, the University of Wisconsin-Madison, and Barr Engineering.
