Water in Wood Dale, Illinois

Water used by the Wood Dale community comes from treated Lake Michigan water that is supplied by the DuPage Water Commission. All water used by Wood Dale residents is safe for consumption, the assurance of quality is provided by the Department of Water Management, Department of the Environment, and the MWRDGC. The average daily water consumption for the city of Wood Dale is around 1.783 million gallons.



The water treatment process has been successfully implemented to protect and safeguard people from contamination. The treatment process involves drawing water from the Lake into an aeration tank to eliminate iron. The water then travels to a tank where polyaluminum chloride and soda ash are mixed into the water. These chemicals allow sediments to bind to the chemicals and ash, which fall to a basin due to their heavy weight and ultimately get removed from the mix. A small amount of chlorine is also blended into the water for disinfection and to remove bacteria – the imperceptible volume of chlorine has no effect on human consumption. The last step is adding soda ash, fluoride and corrosion inhibitors to the water before it is pumped into sanitized reservoirs, water towers and residential homes and businesses.

Wood Dale’s Water Department administers tests and assesses water samples throughout the year for bacteria. There have been no samples testing positive for bacteria. Wood Dale also complies and meets all requirements enforced within the Safe Drinking Water Act, and satisfies all regulations administered by the EPA.

To further ensure safety, the city of Wood Dale’s Water Department has three backup wells that can be used in emergency situations. These back-up wells are tested monthly and yearly for contaminants. It is also mandated that the wells and suction lines maintain a minimum required distance from sources of pollution, further enhancing the quality of water provided to residents. Interested residents are able to request Well test results at any time.

5 contaminants above legal limits.

In some states a small percentage of tests were performed before water was tested, and some contaminants were subsequently removed or diluted. As a result, some reported levels of contamination may be higher than were present at the tap. Results shown are based on individual samples and may not indicate a violation of the Safe Drinking Water Act, which often occurs only after prolonged tests show concentrations above a legal limit.
