Addison Water Company

This report aims to keep Addison residents informed about their tap water quality and the monitoring standards required by the Environmental Protection Agency (EPA). If you have questions about this report, please contact Jim Russo, Water Department Foreman, at (630) 620-2020.

Addison receives all water through the DuPage Water Commission (DWC), via Chicago's Jardine Water Filtration Plant. The village has provided 100% Lake Michigan water since March 1992. The EPA establishes regulations limiting contaminant levels in public water systems, while FDA regulations set similar standards for bottled water to ensure public health protection.

All drinking water, including bottled varieties, may contain small amounts of certain contaminants. Their presence doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, call the EPA Safe Drinking Water Hotline at (800) 426-4791.

Some individuals may be more vulnerable to water contaminants than the general population. People with compromised immune systems—such as cancer patients undergoing treatment, organ transplant recipients, those with HIV/AIDS, elderly individuals, and infants—should seek advice from healthcare providers about their drinking water. EPA/CDC guidelines on reducing Cryptosporidium and other microbial contaminant risks are available from the Safe Drinking Water Hotline (1-800-426-4791).

Water sources (both tap and bottled) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over land or underground, it dissolves naturally occurring minerals and sometimes radioactive materials, and can pick up substances from animal presence or human activity. Potential contaminants include:

• Microbial contaminants: viruses and bacteria from sewage treatment plants, septic systems, agricultural operations, and wildlife
• Inorganic contaminants: salts and metals occurring naturally or from urban runoff, industrial/domestic wastewater, oil/gas production, farming, or mining
• Pesticides and herbicides: from agriculture, urban stormwater runoff, and residential use
• Organic chemical contaminants: synthetic and volatile organic compounds from industrial processes, petroleum production, gas stations, urban runoff, and septic systems
• Radioactive contaminants: naturally occurring or resulting from oil/gas production and mining

1. Where does Addison water come from?
   Addison supplies purchased surface water to Addison, Illinois.
2. Does Addison test its tap water?
   Yes. Like every public water system, Addison must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
3. How do I contact Addison?
   Call 630-543-4100 or visit 1 Friendship Plaza, Addison, IL 60101, or use the contact options on the utility’s website.
4. Does Addison water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is Addison water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
