Leachate is treated in wastewater treatment plant and transported by truck or by sewage system to the nearest treatment plant.
Regional authorities push waste sector operators to face the PFAS (perfluoroalkyl compounds) emergency. In this context the exigence to monitor and remove these compounds from the leachate has an increasing preponderance.
