In late July 2026 Enna municipal officials and Legambiente Sicilia set a joint agenda to align Pergusa‑basin projects with EU environmental standards, upgrade wastewater infrastructure, restore lake monitoring and introduce biological mosquito control. Legambiente’s monitoring confirmed that Pergusa’s microbiological water quality met legal limits, while warning that the shallow lake remains highly vulnerable to climate‑driven evaporation, ecological imbalance, pressure from the nearby motor‑sport circuit and ageing sewage systems.

A week later the European Drought Observatory reported record‑low flows in major rivers across the continent, signalling a deepening water crisis. The Copernicus Climate Change Service recorded historic lows on the Danube, Rhine, Loire and Garonne, prompting water‑use cuts in Veneto and swimming bans on the Piave.

By the end of July a prolonged heat wave pushed the Rhine at Kaub to a historic 25 cm depth and drove sections of the Danube in Romania and Slovakia to record lows, disrupting inland shipping, hydro‑electric power and agriculture. Italy responded with a 50 % cut in water withdrawals from the Adige in Veneto and declared the Po basin in a state of high severity. Swimming was banned in the Piave River and Lake Avigliana after cyanobacteria blooms, and PFAS levels above the EU limit were reported in several northern towns.

The newly formed Sicilian Water Rights Committee continues to press utilities over irregular supply and high water losses. Environmental groups stress that sustained monitoring, sewer upgrades and coordinated regional action remain essential to safeguard Pergusa’s ecological future amid the broader European drought.

## Claims

- Major European rivers have reached record low water levels due to a prolonged heat wave. (corroborated by 4 sources)
- In summer 2026, temperatures above 40 °C were recorded across much of Europe. (corroborated by 3 sources)
- The Danube River reached record low levels in sections of Romania and Slovakia, disrupting waterway transport. (corroborated by 2 sources)
- Inland shipping capacity on the Rhine was reduced to one‑third to one‑half of normal loads, raising logistics costs for European industry. (corroborated by 2 sources)
- Power plants relying on river water for cooling in Europe faced reduced output or temporary shutdowns during the heat wave. (corroborated by 2 sources)
- The Danube at Pfelling recorded a flow of 222 cm, the lowest in the past 30 years. (single source)
- Veneto ordered a 50 % reduction in water withdrawals from the Adige River for irrigation. (single source)
- The municipality of Susegana banned swimming in the Piave River. (single source)
- A bloom of Microcystis aeruginosa caused a full swimming ban on Lake Avigliana. (single source)
- PFAS concentrations exceeded the new 20 ng/L limit in Novi Ligure, Pozzolo Formigaro and Frugarolo. (single source)
- Legambiente’s 2026 monitoring found all sampled points in Sicilian lakes within legal microbiological limits. (single source)
- Sicily created a Committee for the Right to Water to address irregular water supply and high losses. (single source)
- Major European rivers (Danube, Rhine, Loire, Garonne) are experiencing unprecedented low water levels due to drought. (single source)
- Water level at Kaub on the Rhine River fell to 25 cm on 1 August, the lowest since records began in 1880. (single source)
- Low river levels forced the Paks nuclear power plant in Hungary to shut down one reactor unit for the first time in 44 years due to insufficient cooling water. (single source)
- The heat wave increased wildfire risk, prompting large firefighting deployments in Greece and France. (single source)
- The EU’s Copernicus climate monitoring agency reported Europe is warming at twice the global average since the 1980s. (single source)
