Article of Interest – Organic Residuals & PFAAs

Organic chemicals like perfluoroalkyl acids (PFAAs) have been used in society for more than 50 years. While small amounts of PFOA and PFOS have been found in biosolids, the fact is that most human exposure to many of these organic chemicals occurs in the environment we live in and through objects we use such as cooking tools, carpets, furniture, outdoor clothing, among others.
In order to reduce any potential risks to the environment from biosolids, researchers and biosolids managers are currently in the processes of studying and further understanding the presence and movement of PFOA and PFOS from biosolids after land application. Recently BioCycle published a two-part series on PFOA and PFOS. It provides a concise review of the concern and active research.
