MADISON — The state
Department of Natural Resources is asking wastewater
treatment plants to test for polyfluoroalkyl pollution.
The substances, also known
as PFAS, are man-made chemicals that have been used for
decades in products such as fire-fighting foam, non-stick
cookware and fast-food wrappers. Research suggests PFAS
can decrease female fertility, increase the risk of high
blood pressure in pregnant women and lower birth weights.
DNR officials said Monday
they have started sending letters to 125 municipal
wastewater plants asking them to sample and analyze water
flowing in and out of the facilities for PFAS compounds.
The DNR picked the facilities because they're more likely
to receive wastewater from businesses that use PFAS.
The DNR plans to use data
from the sampling to build a plan to reduce PFAS entering
