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.

    This is so unnatural solution, blocking sun ? sun makes water live.. water is life .. live.. hope the scientist could think natural.. so many problems already because of just focusing on solution to 1 problem .. its horrible way indeed..

    Could you not use a hovercraft instead of a boat? Balls are said fine in wind. But mainly I agree with Joanne Marks below, any plastic in water releases Estrogen like chemicals. I don't like to be racist like a certain president but this is a typical American high tech approach to fix a problem. Is there not a lower tech solution? that does not involve putting plastic micro-particles and estrogen chemicals into peoples water. How about the impact on wildlife?
    How about the solution used by the ottomans, underground cisterns. see en.wikipedia.org/wiki/Basilica_Cistern

    Wish I worked for that plastics company.... I'd be *rolling* in it. Also, hats off to the beverage company (I'm guessing Coke or Pepsi) for measuring the water they received (before they used it to make more plastic-filled things...shrug).
