Summary

Story summary

University of Utah scientists found a significant freshwater reservoir beneath the Great Salt Lake, extending to 10,000–13,000 feet.
Airborne electromagnetic surveys revealed freshwater saturates sediments beneath the hypersaline surface, contrary to expectations that it would exist only at the periphery.
The finding could reduce dust pollution from the exposed lakebed, a health concern for nearby communities.
Further exploration is needed to understand the freshwater system and its potential dust-control benefits.
