Monitoring campaigns by Legambiente, specifically the Goletta Verde and Goletta dei Laghi 2026 campaigns, have revealed significant water quality issues across various Italian regions. Findings indicate that 34% of 391 water samples across 19 regions exceeded legal pollution limits. The situation in lakes is described as the worst in seven years, with 54% of samples at river mouths classified as polluted or heavily polluted.

Specific critical sites identified include the Musone river mouth, Aci Trezza, and Lake Sabaudia. Beyond microbiological contamination, other environmental concerns include the spread of the invasive blue crab along the Po River due to drought, and fish concentrations at Rome’s EUR Lake caused by low oxygen and high temperatures.

Inadequate wastewater treatment remains a primary driver of these conditions. Data from the Ministry of Environment and Energy Security shows that 514 urban areas, serving over 14 million people, are discharging non-compliant sewage. This systemic issue, compounded by the climate crisis warming the Mediterranean and drying up lakes, has resulted in four European Union infringement procedures and substantial fines for the country.
