“The death toll from a chemical tank rupture in the U.S. state of Washington climbed to 11 as crews recovered the bodies of all nine missing people, authorities said on Saturday. Two fatalities had been confirmed after the tank containing ‘white liquor’ — a chemical solution of sodium hydroxide and sodium sulfide used in making paper pulp — imploded at a Nippon Dynawave Packaging facility on Tuesday. … The ruptured tank contained about 3.4 million litres of white liquor, and tests confirmed that contamination entered the nearby Columbia River, officials have said, although no ‘negative health impacts’ had been detected on air quality or the city of Longview’s drinking water.” (05/31/26)
