Good job LA – combating drought one bacterial cesspool in the making at a time

This feels like a ‘Choose Your Own Adventure’ book from my childhood.  It’ll be interesting to see how it turns out.

LA’s scheme to cover a reservoir under 96 million “shade balls” may not be all it is touted to be, experts told FoxNews.com, with some critics going so far as to refer to the plan as a “potential disaster.”

 The city made national headlines last week when Mayor Eric Garcetti and Department of Water officials dumped $34.5 million worth of the tiny, black plastic balls into the city’s 175-acre Van Norman Complex reservoir in the Sylmar section. Garcetti said the balls would create a surface layer that would block 300 million gallons from evaporating amid the state’s crippling drought and save taxpayers $250 million.

Experts differed over the best color for the tiny plastic balls, with one telling FoxNews.com they should have been white and another saying a chrome color would be optimal. But all agreed that the worst color for the job is the one LA chose.

“Black spheres resting in the hot sun will form a thermal blanket speeding evaporation as well as providing a huge amount of new surface area for the hot water to breed bacteria,” said Matt MacLeod, founder of the California biotech firm Modern Moon Farms. “Disaster. It’s going to be a bacterial nightmare.”
