And although bottled water gross sales have continued to skyrocket since 2010 ― climbing to a whopping 15 billion gallons of bottled water bought in the US in 2020 ― knowledge reveals and specialists say there are compelling causes to ditch the plastic for good.
There’s some proof that reveals bottled water might include doubtlessly dangerous chemical compounds in its packaging.
Phthalates, additionally referred to as plasticizers, are a category of artifical chemical compounds used to make water bottles and other plastics more durable and flexible. Phthalate publicity has been warned against due to how the chemical compounds have an effect on an individual’s endocrine system, which is the system that produces and releases hormones.
Some studies have discovered that plastic water bottles alone don’t have contamination ranges important sufficient to trigger hurt to bottled water drinkers. Nevertheless, a number of specialists advised HuffPost that as a result of most individuals are already uncovered to endocrine-disrupting chemical compounds from many other sources day by day ― from housecleaning merchandise to some fragrances ― it could be clever to restrict extra publicity to such chemical compounds the place attainable.
The U.S. Environmental Safety Company (EPA) is anxious sufficient about these potential results that it moved final month to designate one other widespread endocrine-disrupting chemical class, often known as PFAS, as “hazardous substances.” These are colloquially referred to as “eternally chemical compounds,” as a result of they’ll stick round within the setting for many years.
Although phthalates and different endocrine-disrupting chemical compounds aren’t normally detected in water at its authentic supply, the plastic surrounding bottled water can contaminate the liquid over time. Levels of contamination differ, however specialists say that plastic-to-liquid contamination is generally exacerbated by two issues: the period of time the plastic and drink (or meals) are in direct contact, and whether or not the plastic has been heated whereas touching the meals or liquid.
Bottled water is regarding on each fronts as a result of it’s typically saved in warehouses for prolonged durations of time after which on modes of transportation the place temperatures might be excessive.
“Sitting in such situations for months and even years earlier than making its method to the patron is a really very long time for such a small quantity of water to be surrounded by a lot scorching plastic,” Dr. Nathaniel DeNicola, an OB-GYN and environmental well being skilled for the American School of Obstetricians & Gynecologists, advised HuffPost.
Emily Barrett, an affiliate professor of biostatistics and epidemiology at Rutgers Faculty of Public Well being, added that the explanation phthalates separate from plastics within the first place is as a result of they don’t seem to be a part of the plastic matrix itself however are loosely sure to it.
“When uncovered to warmth, the chemical bonds can break comparatively simply, permitting the phthalates to leach into the meals or drink contained in that plastic packaging,” she stated, noting that such contamination also can happen throughout manufacturing levels when bottled water is available in contact with PVC — one of many world’s most generally produced plastics, identified for its hardness — and different plastic equipment.
“Water bottles might be prone to contamination due to the extended direct contact between the water and the plastic packaging supplies.”

The quantity of plastic surrounding such a comparatively small quantity of water can be value consideration.
“Water bottles might be prone to contamination due to the extended direct contact between the water and the plastic packaging supplies and huge floor space of contact,” stated Dr. Maida Galvez, professor of environmental drugs and public well being at Icahn Faculty of Drugs, Mount Sinai in New York Metropolis.
Metals, micro organism, plastic items and extra have been present in bottled water earlier than.
Past attainable publicity to such chemical compounds, a number of research have discovered different substances in bottled water.
“Research have discovered traces of prescribed drugs, microplastics, micro organism and heavy metals,” Barrett defined. Certainly, a Journal of Environmental Health study discovered heavy metals resembling silver, barium, cobalt, chromium, copper, nickel, lead and zinc in a number of fashionable bottled water manufacturers.
What’s extra, research revealed in 2019 by the Nationwide Library of Drugs additionally found toxins, micro organism, fungus and “microbiological pollution” in bottled water which can be answerable for completely different illnesses in people, most often gastroenteritis or abdomen flu.
The examine concluded that bottled water is usually thought-about to be secure and sterile, “however, the chance for well being shouldn’t be minimized [when] bearing in mind the microbial metabolic variety and flexibility making completely different species succesful to outlive, and even multiply within the situations provided by bottled waters.”
The Facilities for Illness Management and Prevention has warned that “contaminated bottled water can hurt your well being, together with inflicting gastrointestinal sickness, reproductive issues, and neurological issues.” It states that individuals with weakened immune techniques “could also be extra prone to get sick from some contaminants” and advises what immunocompromised people can look out for on bottled water labels to guard in opposition to the microscopic parasite Cryptosporidium, also called Crypto. The parasite is innocent to most shoppers (one study confirmed that about 80% of North American adults have ingested the parasite earlier than, however most didn’t know that they had it) however might trigger immunocompromised individuals to have “chronic or severe illness and even life-threatening symptoms.”
Past micro organism considerations, testing by Consumer Reports in 2020 discovered worrisome ranges of arsenic in some bottled water as properly. A really small 2018 Frontiers in Chemistry study additionally discovered microplastics ― tiny fragments of plastic ― in 93% of the 259 bottled water samples that had been analyzed. Some such fragments had been giant sufficient to be seen and not using a magnifying glass or microscope.
And although microplastic particles have been discovered in lots of different locations (a 2019 study discovered that microplastics had been within the air surrounding a mountain vary in France), Sherri Mason, creator of the Frontiers in Chemistry examine and a sustainability researcher at Penn State Behrend, told Time magazine in 2019 that such chemical compounds are particularly ample in bottled water. Along with being discovered within the plastic bottle itself, she defined, the act of bottling the water also can trigger “fragments of polypropylene” (used to make bottled water caps) to enter the contents of the bottle. She famous that microplastics have been present in faucet water as properly, however are discovered “about twice as a lot” in bottled water.
Bottled water could also be poor in important pure minerals extra generally present in faucet water.
In 2001, McGill University researchers checked out ranges of important minerals resembling calcium, magnesium, and sodium generally present in faucet water and in contrast the consequence to ranges discovered in lots of manufacturers of bottled water. The staff found that faucet water contained considerably larger ranges of such minerals than U.S. spring water bottled water manufacturers.
Its findings additionally confirmed that ingesting simply two liters of faucet water in some cities can alone fulfill between 6% and 18% of 1’s beneficial each day allowance of calcium — some extent DeNicola stated is of specific significance.
“Too many individuals are getting their vitamin D and calcium from supplemental sources like multivitamins nowadays,” he stated. He stated that some analysis means that, in some circumstances, an excessive amount of calcium by dietary supplements might even take a toll in your coronary heart, so it’s a good suggestion to attempt to get hold of nutritional vitamins and minerals from pure dietary sources as a lot as attainable and to complement as a secondary measure.
And, in fact, plastic bottles are terrible for the setting.
Although this one is a no brainer and has already been covered extensively before, it’s value mentioning. For starters, the life cycle of every bottle of water comes with a hefty carbon footprint that contributes to local weather change. It additionally causes super air pollution as an estimated quantity of only 8.7% of water bottles end up being recycled.
What’s extra, the manufacturing of bottled water has an enormous water footprint as properly. According to NPR, the quantity of water going into packaging, transportation and manufacturing of every bottle might find yourself being six to seven instances the quantity of water that’s inside every bottle.
So, what can we do about this?
How a lot ― if any ― important hurt comes from bottled water varies from individual to individual, the specialists stated. It’s troublesome to measure. As an alternative, they simply need shoppers to learn when making a call.
“The primary recommendation I’ve is to drink water!” Galvez stated. “Secure and wholesome ingesting water is important to life.”
If you’re trying to cut back your plastic bottled water consumption, right here’s what to think about:
Drink faucet water should you’re in a position.
Seems like an apparent reply, however many individuals don’t for a wide range of causes. For some in sure areas of the nation, it’s been actively dangerous to do so.
Many individuals purchase bottled water as a result of they imagine it’s sourced from mountain streams or filtered in a uniquely highly effective or thorough method. However specialists say that mountain water sources are uncommon and is probably not any “purer” than most municipal water sources, and that many fashionable bottled water manufacturers supply their water straight from faucet water.
And although the 1974 Secure Ingesting Water Act legally gave regulatory oversight of public ingesting water in the US to the EPA, the Meals and Drug Administration assumed accountability quickly thereafter. Right this moment, the FDA is answerable for guaranteeing that high quality requirements for bottled water are appropriate with EPA requirements for public ingesting water, however the company acknowledges on its web site that, “in some circumstances, requirements for bottled water and public ingesting water differ,” and that when the “EPA establishes a regular for a contaminant, the FDA both adopts it for bottled water or finds that the usual isn’t needed for bottled water.”
“Faucet water is examined dozens to tons of of instances a day and people checks are required to be publicly obtainable,” Mason advised HuffPost. “This isn’t the case with bottled water, so that you don’t know what’s actually in it.”
Get a filter for sink water.
It’s additionally value noting that the water filtration system utilized in many bottled water manufacturers is probably going no completely different than the type of filtration techniques one should buy for residence use or what comes included with many manufacturers of fridges.
“Our household put in a reverse osmosis filter in our kitchen sink,” Barrett stated. She added: “Regardless of advertising and marketing claims, in lots of circumstances the bottled water you purchase is not any ‘purer’ than water popping out of your faucet.”
Search for different bottles.
“Nobody model of plastic water bottles are safer than one other,” Mason suggested. “If you must buy bottled water, buy it bottled in glass if it’s an choice.”
If the priority is mostly-convenience associated, contemplate investing in a top quality reusable bottle. “Select reusable water bottles which can be stainless-steel,” Galvez stated. “They’re higher for you and for the setting.”
Retailer any plastic bottled water accurately.
Barrett recommended that if one nonetheless desires to drink water bottled in plastic, to “maintain it in a cool place,” and to “drink it comparatively rapidly with out storing it for years,” to keep away from additional phthalate contamination.
“Typically bottled water is unavoidable and that’s OK,” she stated. “However it needs to be a back-up, not your first alternative.”
