PFAS & Testing Results

PFAS in Drinking Water

PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that are resistant to heat, water, and oil. For decades, they have been used in industrial applications and consumer products such as firefighting foam, stain repellants, waterproof clothing, metal plating, carpeting and non-stick cookware. PFAS does not breakdown in the environment easily, and some PFAS can build up overtime in our bodies, which can lead to various health risks.

PFAS may enter drinking water when products or waste materials containing PFAS are discarded, used, or accidentally spilled on land, which can then seep into the ground and infiltrate groundwater. When PFAS are discharged into lakes or rivers, they can contaminate local drinking water supplies. PFAS released by industrial facilities into the air may eventually find its way into rivers and lakes used for drinking water.

PFAS Maximum Contaminants Levels

In August 2020, the Michigan Department of Environment, Great Lakes, and Energy established maximum contaminant levels (MCLs) for seven PFAS compounds. 

ND - Not Detected
NA - Not Applicable (Compound is not analyzed in the EPA 537 Method)

PFAS Sampling Results

In 2018, we launched our PFAS testing efforts. By 2019, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) began a statewide sampling program, conducting monthly sampling in 2019, every other month in 2021, annually in 2022, and quarterly in 2023.

In August 2020, EGLE established maximum contaminant levels (MCLs) for seven PFAS compounds.

The test results brought us reassuring news: our tap water's PFOS and PFOA concentrations were found to be below the maximum contaminant levels established by EGLE.

Test Results: April 2018 -  August 2020

New Sampling Regulations: August 2020 - Present
