The Los Angeles Department of Water and Power dropped the ball Monday.
Actually, it dropped 400,000 of them.
Actually, it dropped 400,000 of them.
The agency started dumping thousands of floating plastic balls into Ivanhoe Reservoir -- the dwarf sibling next door to Silver Lake Reservoir, the neighborhood's crown jewel -- to protect the drinking water supply needed for summer.
The water needs to be shaded because when sunlight mixes with the bromide and chlorine in Ivanhoe's water, the carcinogen bromate forms, said Pankaj Parekh, DWP's director for water quality compliance. Bromide is naturally present in groundwater and chlorine is used to kill bacteria, he said, but sunlight is the final ingredient in the potentially harmful mix.
The DWP drop was designed to stop the three from mingling in the 10-acre, 58-million-gallon Ivanhoe Reservoir. The 102-year-old facility serves about 600,000 customers downtown and in South Los Angeles.
Elected officials, community activists and two dozen DWP officials and maintenance workers grabbed a few balls out of a white tub and tossed them into the aquamarine pool after a brief news conference.
