Why Are 96,000,000 Black Balls on This Reservoir?

The video explores the use of shade balls in the LA Reservoir, initially developed to address the bromate formation issue caused by sunlight exposure. These black, high-density polyethylene balls block sunlight, preventing harmful chemical reactions and reducing evaporation by 80-90%. They also deter birds, improve water quality, and save costs on chlorination. The video discusses the development, testing, and benefits of shade balls, as well as alternative designs considered.
