Researchers discovered Osireion's water has the lowest mineral content and bacteria levels of any sampled well in the area, despite the site being open to tourists. The water is a mix of Old Nile, Recent Nile, and deep paleowater. The hypothesis: Osireion functioned as both a cistern reservoir and natural water treatment facility.
