The Madison Water Utility is testing for PFAS at municipal Well 15 on East Washington Avenue.

PFAS are widely used chemicals found in food packaging, non-stick cookware, stain-resistant fabrics, and firefighting foams. According to Public Health Madison Dane County, low levels of PFAS detected so far at Well 15 are not considered a threat to public health.

City officials believe the chemicals are likely coming from nearby Truax Air Field, where PFAS were found in shallow groundwater and have been used in firefighting foams.

Madison Water Utility decided to ramp up testing from quarterly to monthly in order to gather more data about whether PFAS levels at the well are changing. October tests showed a 5 part-per-trillion increase from tests run in March of last year.

Results should be in by the end of February.
