As California's toxic Salton Sea shrinks, it's raising health alarms for the surrounding community

Salton City, California — Damien Lopez, age 4, has symptoms that many people who live near Southern California's Salton Sea also have.

"His cough gets very wheezy. I try to control him," his mother Michelle Lopez said. 

"Control" often means visiting pediatric nurse Christina Galindo at Pioneers Memorial Hospital.
