Water Quality Reports

Safe Drinking Water


The City of Sterling Heights wants you to know your tap water is safe to drink and that it meets or exceeds all federal and state standards for quality and safety. Sterling Heights is proud of the drinking water it supplies and is honored to provide you with annual water quality reports.

Consumers Confidence Reports


Our water quality data is provided in the form of Consumer Confidence Reports, simply called Water Quality Reports.  These reports contain much more than just testing data. They also provide information regarding the sources of our water, how our water system is protected, and drinking water safety and our health. The City of Sterling Heights will notify the public immediately if there is ever any reason for concern about our water.  We are pleased to provide you with the annual report for 2021, found in the link below.  The 2021 report shows how the water delivered to you has surpassed quality standards as mandated by the U.S. Environmental Protection Agency (EPA) and the State of Michigan Department of Environment, Great Lakes, and Energy (EGLE).

STATEMENT:  from the Great Lakes Water Authority (GLWA) regarding PFAS testing for drinking water systems

The Department of Environment, Great Lakes, and Energy (EGLE) conducts statewide testing for Per- and Polyfluoroalkyl Substances (PFAS). These are man-made compounds used in the manufacturing of carpets, clothing, fabrics for furniture, paper packages for food and other materials that are resistant to water, grease, or stains. They are also found in products such as firefighting foams, cleaners, cosmetics, paints, adhesives, and insecticides.

The Great Lakes Water Authority (GLWA) has been monitoring PFAS since 2009. In our 2017-2021 round of drinking water system screenings, GLWA is pleased to assure the public that these chemicals were not detected. This means that PFAS levels were below that which is measurable under the EPA’s standard analytical methodology for the detection of the compounds. Test results from all five of GLWA’s water treatment plants can be found by clicking the links below:

2018 Results

PFAS are unregulated contaminants. Unregulated contaminants require that GLWA collect data and report that data to EGLE and the EPA. They then combine that data with other research to make a determination about potential future drinking water regulations regarding the contaminants.

We take our responsibility to public health and safety seriously and are in full support of EGLE’s statewide PFAS sampling effort. Additionally, GLWA can confirm that its water remains of unquestionable quality.
