PyroGenesis Canada Inc said it has been selected to provide a $9.2 million land-based system to destroy perfluoroalkyl and polyfluoroalkyl substances (PFAS) in drinking water. The company said the client is a large operator of public water systems, whose name will remain confidential for competitive reasons. PFAS are a group of man-made chemicals found in countless household items such as electronics, cleaning supplies, and non-stick cookware, which can contribute to harmful human health conditions including cancer and hormone disorders.
