Iowa DNR Solicits Alum Application Services for Silver Lake Phosphorus Reduction

This opportunity involves a lake restoration project led by the Iowa Department of Natural Resources (DNR) at Silver Lake in Delaware County, Iowa. - The DNR seeks a contractor to perform two applications of alum (aluminum sulfate) and sodium aluminate to reduce phosphorus levels in the lake. - The goal is to inactivate phosphorus released from lake sediments, improving water quality and reducing algal blooms. - Quantities of chemicals will be determined based on recent sediment core studies. - No specific OEMs or chemical manufacturers are named in the solicitation. - The project is part of the Lake Restoration Program and is a priority initiative involving collaboration with local communities and research institutions. - Notable requirements include precise chemical application and adherence to environmental safety standards.

Description

This contract involves two alum applications at Silver Lake in Delaware County, Iowa, aimed at reducing phosphorus concentrations in the lake to improve water quality. The project addresses eutrophication caused by high nutrient loading, particularly phosphorus, which leads to algal blooms and degraded ecological health. The alum application program will be conducted in two doses to inactivate phosphorus released from lake sediments, thereby enhancing water clarity and quality. The initiative is part of a broader lake restoration effort involving research and community collaboration to manage phosphorus levels effectively.
