Many original PFAS compounds were phased out of production in the early 2000s, but they were replaced with other compounds still being evaluated for safety. Tony Kollasch looks at the presence of these compounds in the environment, as they tend to accumulate in organic tissues and materials, including biosolids from wastewater treatment plants. These biosolids have traditionally been used for their nutrient content as fertilizer on local agricultural fields. Is the landspreading of these materials safe, and is there potential for some uptake of PFAS compounds into the edible portions of food crops? Tony Kollasch provides common sense guidance to the agriculture industry.
