Utah faces costly dust crisis as Great Salt Lake recedes, experts urge refilling
University of Utah researchers identified 70 sq mi of active dust hotspots on the drying Great Salt Lake, estimating $116 million in annual health costs, while state officials say ozone and local construction dust are more pressing.
A University of Utah study identified 70 square miles of “active dust hotspots” on the exposed Great Salt Lake, with potential expansion beyond 100 square miles as groundwater levels fall. Researchers estimate the dust and associated micro-irritants generate $116 million in yearly health expenses and roughly seven premature deaths. State air-quality chief Bryce Bird stressed that ozone exceedances and construction-site dust are more urgent public-health concerns, pointing out that lake dust has not surpassed EPA limits.
Panelists Derek Mallia and David Parrott noted uncertainty about the dust’s composition but agreed that restoring water to the lake is the most affordable solution, contrasting with costly engineering measures modeled after Owens Lake in California. The discussion highlighted the looming economic and health burden if the lake continues to shrink.
