- Nearly 780 million people worldwide do not have access to a source of clean water (water that flows through a household connection, borehole, well, or protected spring).
- In the US, 99.2% of the country has access to clean tap water , but many Americans chose to drink bottled water instead due to concerns about poor taste and contamination .
- Bottled water and clean tap water are virtually identical in terms of purity and taste. In a 2011 study , only one-third of blind taste-testers could correctly identify tap versus bottled water.
- Unlike tap water, however, producing bottled water is an expensive, resource-heavy process that requires crude oil and extra water.
There's nothing quite like the feeling of a pure, ice-cold drink of water.
While some Americans get water from the tap, the rest pay for the bottled variety at a cost of $100 billion a year.
The average cost of a gallons worth of single-serve bottled water in the US is nearly $9.50, according to FoodandWaterWatch . That's nearly three times more expensive than the average price for a gallon of milk , and almost four times the average price for a gallon of regular gasoline . Bottled water costs nearly 2,000 times more than tap water, which costs less than a cent per gallon.
Many people assume that the higher price tag is justified by the health benefits of bottled water, but in most cases, that's not true.
This year's World Water Day falls on March 22 the day is meant to draw attention to disparities in clean-water access around the globe. Worldwide, 780 million people don't have access to a source of clean water .
But for the vast majority of Americans, tap water and bottled water are comparable in terms of healthiness and quality. In some cases, publicly sourced tap water may actually be safer , since it is usually tested more frequently, Plus, bottled water is more likely to be contaminated by microplastic particles than tap water.
"It is wrong to assume that bottled water is somehow cleaner, healthier, or safer than tap water in the US," Peter Gleick, an environmental scientist and the co-founder of the Pacific Institute , told Business Insider.
There are exceptions , however: Water that comes from people's private wells do not see the same rigorous testing as those whose water comes from public sources. And, as was the case Flint, Michigan , some public sources are not properly screened .
Nonetheless, there are plenty of reasons for most people to stop shelling out for bottled water. Here's what to know.
The first documented case of bottled water being sold was in Boston, Massachusetts in the 1760s. A company called Jackson's Spa bottled and sold mineral water for "therapeutic" uses.
Companies in Saratoga Springs and Albany also packaged and sold water .
Americans consume more packaged water overall than people in any other country in the world except China.
Across the globe, people drink roughly 10% more bottled water every year. On a per-capita basis, the US ranks number six in bottled water consumption.
Today, Americans today drink more bottled water than milk or beer. Each person consumes roughly 39 gallons of bottled water annually.

In 2016, Americans drank more bottled water than soda for the first time ever.
"Bottled water effectively reshaped the beverage marketplace," Michael Bellas, chairman and CEO Beverage Marketing's , said in a statement the following year .

But that number could be even higher, some analysts have pointed out , because most sales are for single bottles.
Soda companies are aware of how lucrative bottled water can be corporations like Coca-Cola and PepsiCo have been investing in it.
In 2017, Pepsi bought a 30-second Super Bowl ad to debut its premium bottled water brand LIFEWTR.
"The worst is the false claims made by some 'specialty' bottled waters that claim magical benefits from adding oxygen, or magically rearranging crystals, or various other water voodoo," Gleick said.
He added that "even the mainstream companies have occasionally had ad campaigns that directly or indirectly malign tap water."
Research suggests that for most Americans, water in a bottle is not better than the stuff from your tap. In fact, one report found that almost half of all bottled water is derived from the tap, though it may be further processed or tested.
In 2007, Pepsi (Aquafina) and Nestle (Pure Life) had to change their labels to more accurately reflect this.
"Bottled water is no better regulated, tested, or monitored than tap water, and often less well monitored," Gleick said.

"When there are problems with tap water, the solution is to invest in updating and fixing our water systems, not to turn to bottled water," he added.
In fact, tap water is typically tested for quality and contamination more frequently than bottled water.
The Environmental Protection Agency is responsible for conducting those tests .
Still, the quality of your tap water can vary considerably based on where you live. According to EPA law, you should receive an annual drinking-water quality report, or Consumer Confidence Report, that details where your water comes from and what's in it. You can use the link below to find yours.

However, if you live in one of the 15 million (mostly rural) US households that get drinking water from a private well, the EPA isn't keeping an eye on your water quality.
"It is the responsibility of the homeowner to maintain the safety of their water," the agency says on its website .
The water from some of these wells may not be safe to drink. In a 2011 report, 13% of the private wells that geologists tested contained at least one element (like arsenic or uranium) at a concentration above national guidelines.

Bottled water's recent popularity may be due to rising concerns about the purity of tap water. A 2017 Gallup poll found that 63% of Americans worried a "great deal" about the pollution in drinking water.

That was the highest percentage of concern reported since 2001.
"Trust in our urban water systems is declining because of preventable disasters like Flint, Michigan," Gleick said.
Though some people complain about the taste of tap water, most of us probably can't tell the difference. In a blind taste test done by students at Boston University, only a third of taste-testers identified a tap water sample correctly.

Making bottled water is also an expensive, resource-heavy process.
Like other sources of plastic, the material in bottled water is produced from the byproducts of crude oil . A 2009 study published in the journal Environmental Research Letters revealed that the plastic that went into the bottled water Americans consumed in the year 2007 came from the byproducts of between 32 million and 54 million barrels of oil .
Plus, more water goes into making a bottle of water than simply the contents: North American companies companies use 1.39 liters of water to make one liter of the bottled stuff.

You might be thinking: "Hey, at least the bottles get recycled, right?" Wrong. For every six water bottles Americans use, only one makes it to the recycle bin.
