Researchers tested a bottle of Fiji against a glass of tap water. The results were alarming.

Once upon a time, a young Fiji water brand had what they thought was a brilliant idea for an ad campaign. They targeted a specific city — Cleveland, Ohio, to be exact — and put up billboards poking fun of the city's water quality: "The label says Fiji because it's not bottled in Cleveland," they read.

Clevelanders didn't find it funny. According to the Washington Post, public utilities director at the time Julius Ciaccia decided to test the quality of Fiji water against the city's tap water.

"The results: 6.31 micrograms of arsenic per liter in the Fiji bottle, said Cleveland water quality manager Maggie Rodgers. Cleveland tap water as well as bottled brands Aquafina, Dasani and Evian had no measurable arsenic.

"Before you take a cheap shot at somebody, know what you're talking about," said Cleveland water commissioner J. Christopher Nielson.

It should be noted, of course, that the 6.3 micrograms of arsenic are well within the defined limits set forth by the FDA. But it goes to show — what do we really know about the bottled we're drinking? It may claim to come from "fresh mountain springs" or "rainforest aquifers," but there's a lot going on inside those bottles that most consumers aren't aware of.

The Story of Stuff Project brilliantly tells the story, and explains how bottled water became America's biggest craze — and why it might be time to "take back the tap."

Here are 6 powerful takeaways.

1. Bottled water is more expensive than tap water (and not just a little).

A Business Insider column noted that two-thirds of the bottled water sold in the United States is in individual 16.9-ounce bottles, which comes out to roughly $7.50 per gallon. That's about 2,000 times higher than the cost of a gallon of tap water.

And in an article in 20 Something Finance, G.E. Miller investigated the cost of bottled versus tap water for himself. He found that he could fill 4,787 20-ounce bottles with tap water for only $2.10! So if he paid $1 for a bottled water, he'd be paying 2,279 times the cost of tap.

2. Bottled water could potentially be of lower quality than tap water.

Fiji's marketing campaign not only backfired, it raised all kinds of questions about what's really inside our bottled water.

How was that possible? Sarah Goodman of the New York Times explains:

" Bottled water manufacturers are not required to disclose as much information as municipal water utilities because of gaps in federal oversight authority. Bottom line: The Food and Drug Administration oversees bottled water, and U.S. EPA is in charge of tap water. FDA lacks the regulatory authority of EPA."

Many independent watchdogs and organizations regularly test popular bottled water brands, and continue to find high-levels of contaminants and microplastics in them.

3. The amount of bottled water we buy every week in the U.S. alone could circle the globe five times!

That sounded like it just had to be impossible, so we looked into it. Here's what our fact-checkers found:

"According to the video, ' People in the U.S. buy more than half a billion bottles of water every week.' National Geographic says for 2011, bottled water sales hit 9.1 billion gallons (roughly 34 billion liters).

A 'typical' water bottle is a half-liter, so that's about 68 billion bottles per year. Divided by 52 weeks would be a little over 1 billion bottles of water sold per week in the U.S. Because that's based on a smaller 'typical' bottle size, it seems reasonable that a half billion bottles a week could be accurate.

The Earth is about 131.5 million feet around, so yep, half a billion bottles of varying sizes strung end-to-end could circle the Earth five times."

4. Paying for bottled water makes us chumps.

Beverage companies have turned bottled water into a multibillion-dollar industry through a concept known as manufactured demand. Bottled water advertisements used a combination of scare tactics (Tap water bad!) and seduction (From the purest mountain streams EVER!) to reel us in.

Well, we now know their claims about the superior quality of bottled water are mostly bogus. And research shows that anywhere from a quarter to 45% of all bottled water comes from the exact same place as your tap water (which, to reiterate, is so cheap it's almost free).

5. Bottled water is FILTHY.

It takes oil — lots of it — to make plastic bottles. According to the video, the energy in the amount of oil it takes to make the plastic water bottles sold in the U.S. in one year could fuel a million cars. That's not even counting the oil it takes to ship bottled water around the world.

And once we've guzzled our bottled water, up to 80% of the empty bottles end up in landfills or noxious-gas-producing incinerators. The rest is either recycled or shipped to countries like India where poor people without environmental and labor protections have to deal with it.

On top of all that, the process of manufacturing plastic bottles is polluting public water supplies, which makes it easier for bottled water companies to sell us their expensive product.

6. There are 750 million people around the world who don't have access to clean water.

A child dies every minute from a waterborne disease. And for me, that's the core of what makes bottled water so evil.

The video wraps by comparing buying bottled water to smoking while pregnant. That may sound extreme, but after learning everything I just did about the bottled water industry, I can't disagree.

If you're properly disgusted, here are a few ways you can help destroy the bottled water industry:

1. Don't buy bottled water. Get a reusable water bottle. The savings will add up.
2. Rally your schools, workplaces, and communities to ban bottled water.
3. Demand that your city, state, and federal governments invest in better water infrastructure.
