Zion Water Company

The U.S. EPA establishes regulations that limit contaminant levels in public water systems to ensure tap water safety. Similarly, the FDA sets limits for contaminants in bottled water to provide equivalent public health protection. All drinking water, including bottled varieties, naturally contains at least small amounts of certain contaminants, though their presence doesn't necessarily indicate a health risk.

Water sources (both tap and bottled) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water moves across land or through ground layers, it dissolves naturally-occurring minerals, sometimes radioactive materials, and substances resulting from animal presence or human activity.

Potential contaminants in source water include:

• Microbial Contaminants: Viruses and bacteria from sewage treatment facilities, septic systems, agricultural operations, or wildlife
• Inorganic Contaminants: Naturally-occurring salts and metals or those from urban runoff, industrial/domestic wastewater, oil/gas production, mining, or farming
• Pesticides and Herbicides: From agricultural sources, urban stormwater runoff, and residential uses
• Organic Chemical Contaminants: Synthetic and volatile organic compounds from industrial processes, petroleum production, gas stations, urban runoff, or septic systems
• Radioactive Contaminants: Naturally-occurring or resulting from oil/gas production and mining

1. Where does Zion water come from?
   Zion supplies purchased surface water to Zion, Illinois.
2. Does Zion test its tap water?
   Yes. Like every public water system, Zion 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 Zion?
   Call 847-746-4000 or visit 2828 Sheridan Rd, Zion, IL 60099, or use the contact options on the utility’s website.
4. Does Zion 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 Zion 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.
