<P> Although the response to desalination has been mixed, some areas of California are moving forward with seawater desalination . In December 2015, Poseidon Water completed the construction of the Claude "Bud" Lewis Carlsbad Desalination Plant . This facility, which was approved by the San Diego Water Authority, is responsible for providing water for about 8% of San Diego County's water by the year 2020 . As of December 2015, there are 6 additional seawater desalination plants currently in operation in the state of California . As of May 2016, there are also 9 more proposed desalination plants . </P> <P> Water always gets recycled, via rivers, aquifers, and the atmosphere, but we can also do this directly and intentionally . Water reuse in California is increasingly important, with reclaimed water being used preferably for agricultural irrigation, toilet flushing, and industry (e.g., making concrete, cooling), although some apply direct and indirect potable reuse, risking environmental persistent pharmaceutical pollutant s and other constituents of emerging concern . Treatment should be in accordance with the use and, in many cases, water can be safely and productively recycled back to the same non-potable use . </P> <Table> <Tr> <Td> </Td> <Td> This section needs additional citations for verification .
