Potential Contaminants in Water

To ensure tap water safety, the U.S. EPA establishes regulations limiting contaminant levels in public water systems. FDA regulations set similar limits for bottled water. Some individuals may be more vulnerable to water contaminants than the general population.

All water sources (both tap and bottled) include rivers, lakes, streams, ponds, reservoirs, springs and wells. Water can collect naturally occurring minerals, radioactive materials, and substances from animal or human activity as it travels over land or underground.

Potential contaminants in source water include:

• Microbial Contaminants: viruses and bacteria from sewage treatment plants, septic systems, agricultural operations and wildlife
• Inorganic Contaminants: salts and metals that occur naturally or result from urban runoff, industrial discharges, oil/gas production, or farming
• Herbicides & Pesticides: from agriculture, urban runoff, and residential uses
• Organic Chemical Contaminants: synthetic and volatile compounds from industrial processes, petroleum production, gas stations, runoff, and septic systems
• Radioactive Contaminants: naturally occurring or resulting from oil/gas production and mining

Water Source Information

Oak Brook's water supply is purchased surface water from Lake Michigan, filtered at Chicago's Jardine Filtration Plant near Navy Pier. This advanced facility can process and pump 1.4 billion gallons of high-quality water daily. The water travels from Chicago to the DuPage Water Commission's Lexington Pumping Facility and then to the DuPage Water Commission in Elmhurst. Oak Brook receives water from three separate locations throughout the Village before distribution to homes and businesses.

We are contractually obligated to purchase all water from the DuPage Water Commission. In emergencies, we maintain three deep wells that are regularly tested to ensure safe, clean potable water if needed.

1. Where is my home water shut-off located?
   In case of a water emergency, knowing your shut-off valve location is crucial! The valve is typically located where the service line enters your home, usually near the street. If you can't find it, call us at 630-368-5000 and we'll assist you promptly.
2. What should I do if I notice a pump station with a red light and alarm nearby?
   Our pump stations are monitored by our telemetry system, so an Oak Brook water employee is likely already responding. However, you may call 630-368-5000 to verify our response status. After hours, the same number will connect you to our answering service that will page on-call staff. Please don't attempt to reset or silence the alarm yourself.
3. How do I set up water and sewer service as a new renter in Oak Brook?
   Download the appropriate form from our website's "Downloadable Documents" section, complete it, and submit it at our Administration Office. Alternatively, you can visit our office to obtain the form in person. For any questions, please call us at 630-368-5000 during business hours.
4. Who should I contact about backflow prevention questions?
   Please call our office at 630-368-5000 on weekdays between 9 A.M. and 4 P.M., and our staff will be happy to provide information and assistance regarding backflow prevention requirements and testing.
