Illinois Water Quality Facts and Drinking Water Problems

Nearly half of the water in Illinois is sourced from Lake Michigan. Other ground and surface water make up the rest of the state’s water supply. Illinois is one of the most heavily populated states in the country, which has an affect on the quality of water across the state. Due to issues with wastewater runoff in public water sources, high levels of underground toxins, and complex distribution systems, water quality is often poor, which results in an extensive treatment process before water can be distributed to homes and businesses. Some of the problems that Illinoisans associate with their tap water include discolored water that leaves behind stains, lime or white scale buildup, and general bad taste.
