This isn’t a prank, Los Angeles has turned to more unusual methods to protect the city’s water from the drought. This week, they released 96-million floating shade balls, designed to help protect the water against dust, rain, chemicals and wildlife, as well as prevent 300 million gallons of water from evaporating each year, into the 75-acre Los Angeles Reservoir in Sylmar, California. Continue reading for another video of a truck unloading more of these shade balls into reservoir number two.
“The balls work by floating on the surface and blocking the sun’s rays. As well as protecting against evaporation, they also prevent the chemical reaction that creates the carcinogenic compound bromate. For most people, exposure to bromate – created from naturally-occurring bromide in water -is unlikely to be cause problems. But some people who ingest large amounts of bromate have suffered nausea, vomiting, diarrhea and abdominal pain. The balls also form a protective barrier across the surface that helps keep birds, animals and other contaminants out,” said Mail Online.
