Monitoring campaigns by Legambiente Legambiente, specifically the Goletta Verde and Goletta dei Laghi 2026 campaigns, have revealed significant water quality issues across various Italian regions. Initial findings in the Campania coast, specifically within the provinces of Napoli, Caserta, and Salerno, showed that 83% of sampling points exceeded legal limits for microbiological contamination. High concentrations of Escherichia coli and intestinal enterococci were noted, particularly near river mouths, suggesting issues with wastewater treatment infrastructure. Broader national data from the Goletta Verde and Goletta dei Laghi 2026 campaigns indicated Findings indicate that 34% of 391 water samples across 19 regions exceeded legal pollution limits. The situation in lakes was 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, with data driver of these conditions. Data from the Ministry of Environment and Energy Security showing shows that 514 urban areas areas, serving over 14 million people people, are discharging non-compliant sewage. This systemic issue 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.
