Great Salt Lake

The United States' largest magnesium producer, US Magnesium, filed for bankruptcy in September, leaving behind over $100 million in environmental cleanup costs at its Rowley plant near Utah's Great Salt Lake. The facility, a Superfund site since 2009, has a history of releasing toxic waste, including acidic wastewater and hazardous chemicals. State and federal regulators are pushing for liquidation to ensure accountability, amid disputes over ongoing remediation efforts.
