You are now in California and the U.S. category.

California is expected to officially start up its second desalination plant in April, which takes seawater and makes it potable. The first one opened in December 2015 in Carlsbad that is near San Diego while the next one will be in Santa Barbara that is north of Los Angeles. And 15 more are on the table there. Is this a global solution for the billions without access to potable or sanitized water? Can desalination be done in a way that is minimizes harm to the ocean and that uses clean energy to run its operations?

As California waited Monday night to see if President Donald Trump would grant Gov. Jerry Brown’s request for emergency funding for 10,000 evacuees who lived in the shadow of the Oroville Dam, FEMA began preparing for the worse. The federal disaster-management agency’s Region 9, which oversees California and other Western states, has mobilized a 24-hour task force to coordinate its response with state and local agencies, said Mary Simms, a spokeswoman.

The area around a huge dam at California’s second-largest reservoir is in a state of emergency, with some 180,000 residents ordered to evacuate the area Sunday out of fears that part of Oroville Dam could fail. A glimmer of hope arrived late Sunday night, when officials said water had finally stopped pouring over the dam’s emergency spillway. The secondary spillway was in use because the main spillway had developed a huge hole, stressed by the need to release water accumulated from California’s wet winter — and brought to a new crisis point by last week’s heavy rains.

Sacramento County advised residents in the Tyler Island area south of Walnut Grove to evacuate Monday due to a compromised levee. About 20 homes are in the area, said Sacramento County Water Resources spokesman Matt Robinson. Tyler Island is protected by a ring levee. The county expected imminent failure of the North Fork Mokelumne River levee, the National Weather Service warned early in the afternoon. Robinson said there was some disintegration on the land side of the levee but no water has gotten through. Workers are piling rocks at the weakened point to shore it up, he said.
