The city of Los Angeles recently adopted a new tactic in battling the ongoing and crippling drought. In what looks like a child’s wildest imagination, the city dumped 96 million “shade balls” into their reservoirs.
According to a recent Washington Post article, covering the reservoirs with black “shade balls” helps reduce evaporation by blocking out the sun. Also, by blocking out the sun the balls help prevent the chlorine from reacting with the sunlight to become bromate which is a suspected carcinogen.
Officials estimated that the “shade balls” will help save 300 million gallons of water each year. That amount is a drop in the bucket compared to the 13.6 billion gallons of water used by Los Angeles over the course of one month. But in these drought plagued times, saving every drop of water is a step in the right direction.
