A dashboard-style ArcGIS map displays PFAS-related data for Michigan. At the top is a row of six data summary boxes with icons: “PFAS Sites” showing a purple circle and the number 342; “PFAS Areas of Interest” with a pink circular glow icon and the number 39; “PFAS Surface Water Samples” with a teal square and the number 4,053; “Treatment Works with PFAS Data Sites” with a black-outlined teal diamond and the number 201; “FCMP Sampling Sites” with a blue diamond and the number 1,046; and “Public Water Supply Sampling Hexbins” showing the number 1,449. Below, a map of Michigan is covered with numerous colored point markers corresponding to these categories. On the right side, a legend lists each category with matching colored symbols and checkboxes. Small map controls appear on the left side, including zoom buttons and layer toggles.

What is PFAS?

Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals that include perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). PFAS have been used globally during the past century in manufacturing, firefighting and thousands of common household and other consumer products.

These chemicals are persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. In recent years, experts have become increasingly concerned by the potential effects of high concentrations of PFAS on human health.
