Draft Canadian Soil and Groundwater Quality Guidelines for the Protection of Environmental and Human Health – Perfluorooctane sulfonate (PFOS) are available for public review and comment until September 7, 2018.
PFOS does not occur naturally; it is released into the environment from anthropogenic sources. PFOS is present in numerous products such as firefighting foams, insecticides, coatings used for textiles and paper, and cleaning products. PFOS can be released directly into the environment as a result of its production, use (in consumer, commercial and industrial products) and disposal, or it may result indirectly from the biodegradation, photo oxidation, photolysis and hydrolysis of precursor perfluorochemicals.
