Water Quality Reports

We take water quality very seriously. When it comes to complying with strict federal regulations for delivering clean, quality drinking water, we’ve consistently scored among the highest of all water companies.

Water Quality Fact Sheets

Illinois American Water has created the following fact sheets to help describe certain water quality subjects. These one- and two-page sheets focus on a variety of water quality questions customers often have.

Aesthetics - causes of discolored water

Chlorine - a necessary ingredient in the treatment of drinking water

Hardness - causes of the white residue on glassware, dishes, etc.

Lead - your home's plumbing is the most common source of lead in drinking water

Taste and Odor - causes of unusual tastes and orders in drinking water

In the past several years, and all over the country, we’ve received more than 150 awards for superior water quality from state regulators, industry organizations, individual communities, and governmental and environmental agencies. Visit our Accolades section to view some of our recent awards.


We provide our Water Quality Reports – also called Consumer Confidence Reports -- to our customers annually.
