Illegal dumping (abbandono dei rifiuti) is a serious problem in parts of Italy, particularly in Campania, where the phenomenon of Terra dei Fuochi — land polluted by organised illegal waste disposal — became a major national scandal. Ordinary citizens can report dumping via the municipality or the Carabinieri forestali.
