Bottled Water

Bottled Water Impacts The Environment ‘3,500 Times Greater Than Tap Water,’ Research Shows 

Scientists have found that the impact of bottled water on natural resources is 3,500 times higher than for tap water. 

The research specifically examined the impact of bottled water in Barcelona, where the demand for single-use bottled water has increased in popularity in recent years despite the city’s improvements to their tap water quality.

The Barcelona Institute for Global Health (ISGlobal) found that if the city’s entire population drank bottled water, the city would be paying 3,500 times more on resource extraction than if they all drank tap water; it costs about $83.9 million a year. 

The impact of bottled water on ecosystems is also 1,400 greater than tap water. 

The lead author of the study, the ISGlobal researcher Cristina Villanueva, said: “Health reasons don’t justify the wide use of bottled water. Yes, strictly speaking, drinking tap water is worse for local health, but when you weigh both, what you gain from drinking bottled water is minimal. 

“It’s quite obvious that the environmental impacts of bottled water are higher compared to tap water.”

In the US, about 17 million barrels of oil are required to produce the plastic needed to meet the annual bottled water demand. Bottled water in the UK is also 500 times more expensive than tap water. 

“I think this study can help to reduce bottled water consumption, but we need more active policies to change that.”

“For example, in Barcelona, we could have more education campaigns to make the public aware that the health gains from drinking bottled water are minor compared to the environmental impacts. We need to improve access to public water, to public fountains, to public buildings where you can bring your own bottle and don’t need to buy one,” Villanueva explained. 

“We need to facilitate access to public water in public streets. People trust bottled water because advertisers have done a good job of convincing people it’s a good option, so we need the effort on the other side.”
