The tragic chemical tank rupture at a Nippon Dynawave Packaging facility in Longview, Washington, has resulted in a total of 11 confirmed deaths. This includes the recovery of nine workers who were previously reported missing. The incident occurred when a storage tank containing approximately 900,000 gallons of a chemical solution known as 'white liquor' imploded. Recovery crews worked diligently throughout the week, utilizing drones to survey the area and sifting through debris to locate the victims. While contamination from the incident was detected in the nearby Columbia River, authorities stated that tests have not revealed any adverse effects on local air quality or the drinking water supply in Longview. The cause of the tank rupture remains under investigation. Nippon Dynawave Packaging, which operates the facility, is a wholly owned subsidiary of Japan’s Nippon Paper Industries, the second-largest paper manufacturer in Japan. The facility was acquired in 2016 for $225 million from Weyerhaeuser. As recovery efforts conclude, local authorities will continue to investigate the circumstances surrounding this devastating accident.
