A chemical tank rupture at a Nippon Dynawave Packaging facility in Washington state on Tuesday resulted in a chemical spill and killed at least two people, with nine others still missing as of Wednesday. Fire department officials confirmed that contamination from the "white liquor," a solution used in paper pulp production, entered the Columbia River. Recovery efforts are underway but described as hazardous. Governor Bob Ferguson called it potentially the deadliest industrial tragedy in modern state history. While testing confirmed contamination in the river, officials stated there are no identified negative health impacts on air quality or the city's drinking water, though a dozen carp have died.
