The State of Illinois Lead and Copper Rule requires that all Community Water Supplies sample their drinking water for potential lead contamination. Lead in drinking water can cause serious health problems, especially for pregnant women and young children. Although lead is a common metal found throughout the environment, it seldom occurs naturally in water supplies like lakes and rivers. Lead enters drinking water primarily as a result of the corrosion of lead-containing materials in distribution system, such as lead services lines and lead-based solder used to join copper pipe. As the City has no known lead service lines, we are required to perform testing every three years. Testing will once again be completed in 2026. The results are made available through the annual Consumer Confidence Report. The most recent report can be viewed here.
