Mayan city had sophisticated water purification system

The video explores the discovery of an advanced water purification system used by the Ancient Maya in Tikal over 2,000 years ago. Researchers from the University of Cincinnati, led by Kenneth Tankersley, found that the system, which utilized limestone, quartz, and zeolite, was highly effective and could still work today. This technology was crucial for building cities in the jungle, where water sources often contained harmful bacteria.
