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.

    crazy the one veritasium video I don’t watch is the one that gets 30 million views . anyway, let’s get this video to 96 million views ??

    So, they spent $33 million dollars on plastic balls to prevent bromide and chlorine from turning into bromate when activated by sunlight...
    Sweet, that'll totally work out, as long as people to remember to only drink water at night.

    If each shade ball is 0.34 cents like he said that means 96,000,000 costs 32,640,000 dollars.

    What about carbon dioxide? There’s a life in water anyway. Living forms are breathing. And when you cover the water surface you stopping gas exchange, and that can poison water. That’s a small ecosystem and by doing that you destroyed that

    PEHD is not resistable to sunshine and atmospheric influences . Thermal expansion of the HDPE pipes is more than likely and that's why plastic pipes always should be underground . Hittind and rubbing balls one to another can also make them desintegrated . Plastic polimeres are a petrol product and in water can form dioxins :)

    Uhh, why do I get the feeling this is going to be an issue?
    Soon we're going to be filling other large bodies of drinking water with these black balls. How do you think this will mess with the weather and lake life...?
    After that, start expecting all sorts of countries being forced by America to put black balls in the ocean to cool the ocean waters and to prevent evaporation so we have fewer hurricanes.
    Hurricanes can be really sad and devasting and I wish death on no one but they're also a part of nature and are just as important as other natural things like volcanoes so I have a problem with this.

    We are messing with the earth just so we can have drinking water that was already FINE!!
    (btw I live in Texas, I know what hurricanes are like so don't try to say I don't know what hurricanes are like.)

      No, they don't, because enormous molecular chains like those found in petrochemicals are easily filtered out. As for the reservoir, it's a big puddle that would have been dry land otherwise, not the Great Barrier Reef. Its astonishingly superfluous ecosystem doesn't matter at all.

    So if the water is stored in the reservoir after it gets treated, does it get filtered again before it reaches people's houses? I find it odd that the water is stored in an open trench and then piped into homes without being treated again

    • SAW Gunner
      SAW Gunner Pirms dienas

      The missing step you're looking for is filtration, which takes place at the pumping station and in everybody's water heater. It may not sound like much, but it's more than enough as the end to a multi-stage process.
      The Water Treatment Facility does major waste processing, primary (large debris) filtration, chemical sterilization, ph balance, fluoride treatments, all that good stuff. The water is nowhere near good enough to drink yet, so it goes to a reservoir of some type to settle. The mechanic is called floccation, which is just allowing bigger particles to clump together and sink or adhere to the sides. Natural aeration of water and microbiological processes can help this, as in a lake, or screens in a water tank.
      The last step is the filtration, which only requires floccation to be done previously so filters don't get gummed up all the time. You might not think it at first, but even simple filters like sand/charcoal mixtures will scrub virtually all micro-organisms, as they are considerably larger than water molecules. The most modern filters, hardly in use anywhere, are made of graphene that can scrub friggin' RADIATION out of water, no kidding. Being made of carbon, properly structured, they'll capture any ionized particles. Water just keeps getting safer.

    Why wouldn't they use a fan boat. N not risk damaging three balls. This planets been ABSOLUTELY RUINED BY THE RICH SATANISTS!

    Soooooo the water is filtered before putting out in the open where dirt and bird poop or someone wanting to contaminate the water can happen, just water out in the open, open access to bugs too, all open and that's what you drink?
