California water officials have approved $34.4 million in grants to eight desalination projects across the state, including one in the East Bay city of Antioch, as part of an effort to boost the water supply in the wake of the state’s historic, five-year drought. The money comes from Proposition 1, a water bond passed by state voters in November 2014 during the depths of the drought, and it highlights a new trend in purifying salty water for human consumption: only one of the projects is dependent on the ocean.
