SADORUS — The village is making plans to begin treating its water system, which has been pumping out water that residents complain tastes and smells bad.
Kerry Gifford, general manager at Sangamon Valley Public Water District, which runs the village's water system, recommended improvements to both infrastructure and treatment.
The village's wells are 106 feet deep, and water quality is suffering because of the presence of high levels of organic matter built up on the pipes, Gifford said. The organic material removes chlorine from the water and causes the taste and odor problems.
To improve water quality in the short run, Gifford recommended adding high concentrations of Clearitas, a chemical designed to disinfect water mains, followed by flushing. The water plant would also switch from gaseous chlorine to a liquid bleach system.
As a long-term solution to water quality problems, Gifford recommended removing organics from the wells through the use of an anionic pressure filter. That would allow the village to maintain compliance with Environmental Protection Agency limits on trihalomethanes, byproducts of the disinfection process that can lead to health risks at high levels.
