Scientists probe Gaza sewage link to algae bloom that shut Israeli desalination plants

On 5 September, Middle East Eye reported that scientists were investigating whether untreated wastewater discharged from Gaza had contributed to a large microalgae bloom that forced the temporary shutdown of five of Israel's six coastal desalination plants. The shutdown followed a rapid rise in seawater turbidity that began on 30 August, when the Israel Water Authority said most of the country's desalination facilities were taken offline for a second time within 24 hours. Subsequent reports described microscopic algae clogging the intake screens, prompting emergency well pumping and measures to protect household water supplies and agriculture.

Both claims were confirmed. The Water Authority stated on September 1, 2026, that most of Israel's desalination facilities were taken offline for a second time within 24 hours due to a rapid increase in seawater turbidity. Additionally, on the same date, five of Israel's six desalination plants were stopped because of high seawater turbidity.
