Tap water quality in Chicago, Illinois? Is it safe to drink?
The Tap Water Quality in Chicago, Illinois is generally considered to be safe and meets all federal and state regulations. The local water utility that serves the Chicago area is Chicago Department of Water Management.
Key Points about Chicago's Water Quality:
- Source: The primary source of Chicago's water is Lake Michigan. The city operates various purification plants that treat and purify the water before it reaches residents.
- Testing and Standards: The Chicago Department of Water Management conducts regular and rigorous testing to ensure that the water quality meets the standards set by the Environmental Protection Agency (EPA) and the Illinois Environmental Protection Agency (IEPA).
- Water Hardness: Chicago's water is moderately hard, with a significant amount of minerals like calcium and magnesium. This can cause some concerns for residents, such as scaling in pipes and appliances.
- Common Concerns: While the tap water is generally safe, there are occasional concerns related to lead contamination, especially in older homes with lead pipes. The city is actively working on replacing these old pipes and recommends that residents use water filters certified to remove lead.
Overall, the tap water in Chicago is safe for drinking and everyday use, but residents are encouraged to use water purifiers and water softeners to protect themselves. This is especially important in older homes where the risk of lead contamination is higher.

What do we do? How do we help?
We have developed the TDSBot, an inexpensive IOT device that monitors, in real time, the Incoming and Outgoing TDS levels, temperature, flow rate and cumulative volume of water filtered. Easy to install, it works with all water purifiers including, sediment, GAC, Carbon, Micro, Ultra, Nano and Reverse Osmosis water filters. Key benefits:
- Know the incoming and filtered water quality in real time.
- Know the volume of water filtered by day, week, month and total.
- Know in advance when to change filter cartridges. Too often we tend to realize that they need changing after the water purifier has stopped working or worse, when the water smells bad.
- Change filters only when needed. Sometimes filters perform longer than their standard life due to better incoming water or lower usage. Reduce waste and save money.
- Quality data collected is aggregated to show real time water quality data to all the community.
TDSBot can be installed on water purifiers from Pentair, Culligan, 3M, Brita, BWT, iSpring, and most other brands. Supports sediment, GAC, Micro, Ultra, Nano and Reverse osmosis filters. It can remotely monitor filters attached to Coffee machines, Ice makers, soda fountains, water dispensers, ovens, laundry & dish washing, car wash found at Cafes, convenient stores, healthcare facilities, hotels, offices, restaurants, colleges, schools, hydroponic systems, and many more.

Learn About Water Quality
* A definition specific to a few codes is that “Safe drinking water” means water that meets all primary and secondary drinking water standards. Drinking water standards are set based on potential health impacts and also take into account the cost to meet the drinking water standard. Also, the U.S. Environmental Protection Agency (EPA) defines drinking water as safe when humans can drink it with low risk of immediate or long-term harm to your health. Although there may be health risks associated with certain contaminants found in drinking water not all contaminants are necessarily harmful.
