Dear resident:

As this report outlines, Chicago’s tap water meets or exceeds all standards set by the U.S. Environmental Protection Agency for safe, clean drinking water. Issued annually, this report details information on results above detection limits for annual certified testing of Chicago’s drinking water.

The City of Chicago Department of Water Management (DWM) continues to deliver almost one billion gallons daily of clean drinking water to residents of Chicago and the surrounding suburbs. DWM works tirelessly to keep our water clean and safe by:

  • Performing over 600,000 analyses per year of tap water at every step in the treatment process and adjusting treatment protocols as necessary
  • Using corrosion control in our water to minimize the risk of contaminants leaching from plumbing
  • Replacing miles of water and sewer mains to increase reliability and efficiency
  • Offering free water pitchers and six cartridges that are NSF-certified to remove lead and providing complete instructions for flushing water through plumbing to residents and businesses where there is water infrastructure work being done in the vicinity
  • Offering free residential water testing by a certified laboratory.

We are also taking important actions to address the legacy problem of Chicago’s many lead service lines. For the first time, the City now has two programs designed to assist residents who would like to replace with lead service lines. The Equity Program provides a free replacement to residents who meet income and water quality requirements, and the Homeowner-Initiated Program waives up to $3,100 in permit fees for those who wish to replace their lines.

It remains my priority to protect our exceptional water source, Lake Michigan, from polluters and invasive species and to create a strong, efficient water system that provides safe, clean drinking water for every Chicago resident.

Mayor Lori E. Lightfoot
