Algonquin Water Company

The U.S. EPA establishes regulations that limit contaminant levels in public water systems to ensure tap water safety. Similarly, the U.S. FDA sets standards for bottled water to provide equal public health protection. All water sources—whether tap or bottled—naturally contain some level of contaminants, though their presence doesn't necessarily indicate a health risk.

Water sources include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water moves across land or underground, it dissolves naturally occurring minerals, sometimes radioactive materials, and substances from animal or human activities. Potential contaminants include:

• Microbial Contaminants: Viruses and bacteria from sewage treatment facilities, septic systems, agricultural operations, or wildlife
• Inorganic Contaminants: Salts and metals occurring naturally or resulting from urban runoff, wastewater discharge, oil/gas production, mining, or farming
• Pesticides and Herbicides: From various sources including agriculture, 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

For additional information about contaminants and potential health effects, contact the U.S. EPA's Safe Drinking Water Hotline at (800) 426-4791.

1. Where does Algonquin water come from?
   Algonquin supplies groundwater to Algonquin, Illinois.
2. Does Algonquin test its tap water?
   Yes. Like every public water system, Algonquin 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 Algonquin?
   Call 847-658-2700 or visit 2200 Harnish Dr, Algonquin, IL 60102, or use the contact options on the utility’s website.
4. Does Algonquin 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 Algonquin 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.
