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.

    Can't be good for water quality as the plastic degrades under intense sun..I don't care what they say about UV resistant,its a lie. Especially black plastic...must be leaching chemicals into the drinking water. What an ugly and unnatural answer to algae and evaporation.

    WHY I DONT UNDERSTAND IS WHY WE HAVE THIS PROBLEM IN THE FIRST PLACE. WHY WERENT THOSE CHEMICALS TESTED IN DIRECT SUNLIGHT. AND WHY NOT SPEND MONEY ON OUR DRINKING WATER. BECAUSE WE ALL KNOW YOU SPEND 100 OF MILLIONS ON STADIUMS

    time will tell if those balls are inert?.. and uv rays from sunlight kills bacteria so how could putting shade over it make it safe from Bacteria?

    Why? Because the bromide in the reservoir water turns into bromate, a cacrinogenic compound, under direct sunlight. See 3:06
    why not other shade solutions? See 4:42
    they weren't an new invention, shade balls were originally invented to stop birds and wildlife from "using" water bodies like ones that are near airport runways or contain toxic materials etc. see 5:34
    See 5:50 for a bird getting sucked into a airplane jet engine lol
    See 6:30 for R and D testing on the shade balls
    they're black because they need it to block out all sunlight. 6:45
    See 7:17 for why not other colours
    Coincidentally, the shade balls also solved the problem with algae. see 8:22
    yes, they do reduce evaporation. see 9:01
    how much are they? they were 3 for a dollar. 10:07
    balls are a better shape than any other because they don't stack and can adapt the changing water level. see 10:50

    years ago there was an hotel in Kansas City MO. The pool was in door outdoor , meaning a garage door was put down in the winter . During winter the door seperated inside pool from outside so to speak . The outside of the pool had tons of plastic balls to help keep the water warm ...

    It is known that plastic from bottles leaches into the water they contain! thats why they have a shelf life! and someone thought it was a good idea to contaminate everyones drinking water? has some one lft their brain somewhere? and why is no one being taken to court?...

    The guy who produce those balls is probably close to the people who invented that stupid regulation. I bet that the environmental impact caused by the production of those balls is bigger than the harm caused by the substance formed in the water if left uncovered.
