Perfluorochemicals in Biosolids

Are perfluorochemicals widespread in biosolids?

"“We are finding that, for perfluorochemicals, they are showing up where we didn’t expect them to be. The levels vary, but these seem to be universal chemicals that are showing up everywhere,” Hora adds.

EPA recently completed a survey of organic contaminants in sludge but did not measure perfluorochemicals. “When the study started, we didn’t have a method,” says Rudzinki. “We won’t be able to analyze those samples now because they are stored in Teflon containers,” she adds."

An interesting and credible journal article on the major data gaps that exist in relation to waste sludges (biosolids) and waste waste water treatment.
