What is a Water Quality Report? Illinois American Water publishes an annual document detailing your municipal water quality in accordance with state and U.S. Environmental Protection Agency (USEPA) regulations. This report aims to enhance understanding of water quality standards and highlight the importance of protecting water resources.

At our Belleville laboratory, we perform thousands of tests annually, monitoring water quality throughout the treatment and delivery process. In 2017, we tested for hundreds of contaminants, including those with federal and state maximum allowable levels. This overview presents last year's (2017) water quality results with details about your water composition.

Source Water Information: The West Suburban community receives surface water from Lake Michigan, purchased from Chicago through Bedford Park Village and American Lake Water Company. Illinois EPA considers all public water supply surface water sources potentially vulnerable to pollution, necessitating mandatory treatment including coagulation, sedimentation, filtration, and disinfection.

Primary pollution sources in Illinois lakes include agricultural runoff, septic systems, and shoreline erosion. The IEPA has completed a source assessment for Chicago, available upon request. Chicago has one near-shore intake vulnerable to stormwater runoff, marinas, and shoreline contamination sources. Two offshore intakes are situated at distances where shoreline impacts are unlikely to affect water quality.

Environmental Stewardship: Water is one of our most precious natural resources. Our environmental protection efforts include student education programs, community event participation, and environmental partnerships. We reach thousands of students yearly through educational initiatives, our Mobile Education Center, and STEM partnerships. We participate in watershed celebrations, river cleanup efforts, and have awarded over $195,000 to 51+ Illinois water protection projects since 2009.

1. What contaminants are being monitored in Riverdale's water supply?

   Riverdale regularly tests for regulated contaminants including Bromodichloromethane, Chloroform, Chromium (hexavalent), and Total trihalomethanes (TTHMs), among others.

2. Where does Riverdale's water come from?

   Riverdale sources its water from purchased surface water originating from Lake Michigan.

3. How is water hardness affecting my home?

   Elevated water hardness levels can cause scale buildup in pipes, reduce appliance efficiency, and require more soap for cleaning tasks.
