Water desalination

People living in Punta Chueca, home to the Comcáac, have struggled with a lack of fresh water for generations.

Desalination brings fresh water — and concern — to an Indigenous village in northern Mexico

Desalinization Plant Proposed in Florida

The area around Tampa, Florida is running out of water. So authorities are turning to an unconventional solution: they want to build a seawater desalination plant on the edge of Tampa Bay. As Tanya Ott reports, critics of the plan say it substitutes one environmental problem for another.
