Water Quality Reports and Standards

The Village of Arlington Heights Water Utility is proud to provide high-quality drinking water that is clean and safe for you and your family to consume. In fact, the water supplied by the Village complies with all U.S. Environmental Protection Agency (USEPA) standards, including those for lead.

It is important to note that there is no adverse situation currently affecting the quality of our water supply. The Village simply wants water consumers to be informed as much as possible when it comes to your drinking water.

Beginning in 1985, the Village changed from a deep well ground water source to Lake Michigan surface water. The City of Evanston provides complete water treatment and filtration of all water supplied to Village of Arlington Heights municipal water customers. The Evanston plant adds fluoride and chlorine to the water in accordance with State and Federal guidelines. Additionally, the Evanston plant adds poly orthophosphate as a corrosion inhibitor to guard against lead and copper contamination of the drinking water supply. The Northwest Water Commission (NWC) receives water from the Evanston plant and distributes the water to the four NWC member communities, which includes Arlington Heights.

Water Quality Reports
The 1996 Safe Drinking Water Act passed by Congress mandates that every public water supply in the United States prepare and distribute an annual report on water quality. This annual report to water consumers in Arlington Heights characterizes the quality of our drinking water. The format of this report is regulated by the United States Environmental Protection Agency (USEPA). USEPA requires certain mandatory language and data in this report. These informational items must be published every year in the Village’s Water Quality Report.

The Village of Arlington Heights sources its water from the Northwest Water Commission which purchases treated water from the City of Evanston. If you want to know more about PFAS and their presence in drinking water, please see this letter from the Village of Arlington Heights Superintendent of Utilities.

The City of Evanston also created the following page which summarizes PFAS sampling results HERE.
