400,000 Balls Cover Ivanhoe Reservoir by Gerd Ludwig

In 2007, the Department of Water Protection in Los Angeles detected high levels of bromate, a carcinogen that forms when bromide and chlorine react with sunlight, in Los Angeles’s Ivanhoe Reservoir. Bromide is naturally present in groundwater and chlorine is used to kill bacteria, but sunlight is the final ingredient in the potentially harmful mix.

The 102-year-old facility serves about 600,000 customers downtown and in South Los Angeles. When the Department of Water Protection realized the problem, they began construction of a new underground reservoir in Griffith Park, but while the new facility was being built they had to determine a way to keep the sunlight out of the water, so they used 400,000 plastic balls which resulted in this spectacular spectacle.
