10 workers are quarantined inside the Claude Lewis Carlsbad Desalination Plant in Carlsbad, California for the next three weeks. 

The workers are monitoring and adjusting gauges and switches, watching for leaks, and completing other tasks needed to safeguard San Diego County’s only significant local source of drinking water. All 10 volunteered themselves. The Carlsbad plant is home to 40 employees overall, reported the San Diego Tribune.

The request for volunteers was a precaution against the spread of COVID-19, reported the San Diego Tribune.
