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

I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they're there. The first time I heard about shade balls the claim was they reduce evaporation. But it turns out this isn't the reason they were introduced.
Huge thanks to LADWP for arranging this special tour for me. Next time let's put the GoPro on the submersible!
The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the main reason they are on the reservoir is to block sunlight from entering the water and triggering a chemical reaction that turns harmless bromide into carcinogenic bromate. This effect occurs with prolonged exposure to bromate so regulators insist that levels be kept below 10 microgram per liter on average over a 12 month period.

With the increasing concern about microplastics contamination (e.g. accumulating in fish) and the lack of knowledge about how our bodies react to them, I can imagine that these PE balls increase the amount of microplastics in the water reservoir. Can someone comment on that?

The sun heats up the plastic, it leeches into the water supply, giving you all cancer.

In Lake Mead, these have been used for years to prevent evaporation. The use for this lake is very interesting. It looks like they could get by with 30 million less balls, though. Makes it kind of hard to swim! LOL!

So, the filtration takes place before the reservoir... Then how can you store drinking water out in the open? Some birds shitting into it, or rain, sand, other particles polluting it? How is this working?
