Is Bottled Water Really Safer Than Tap Water? 7 Shocking Facts

Bottled Water Really Safer Than Tap Water? Bottled water faces a never-ending debate: Can bottled water really be safer than tap water? Many consumers consider tap water in some suspicion, whereas bottled water is sparkling clean and easier to consume. However, if bottled water is worth spending extra money and involves more harm to the environment compared to tap water or if tap water is just at least as safe or even safer, things have never been clearer than in recent history.

In this article, we will explore seven astonishing facts pertaining to the safety of bottled water, regulatory measures concerning it, and how it compares to tap water. Chances are that you will be shocked at how often really bottled water isn’t what it claims to be.

Bottled Water Really Safer Than Tap Water?

1. Bottled Water Isn’t Necessarily Safer Than Tap Water

It is one of the most convincing arguments for preferring bottled water over tap water: bottled water is safer. This statement, as revealed by different researchers, is nothing but a bluff. For example, in the United States, both bottled and tap water are regulated to be safe, but the EPA sets stricter standards for tap water than the FDA does for bottled water.

Tap Water Regulation:

  • The EPA enforces strict rules on municipal water suppliers, requiring them to test for harmful contaminants such as lead, bacteria, and pesticides.
  • Water quality reports must be publicly available, allowing consumers to know exactly what’s in their tap water.

Bottled Water Regulation:

  • The FDA oversees bottled water, but testing isn’t as frequent, and companies are not required to disclose their water sources or test results to the public.
  • Some bottled water brands may not undergo independent testing, relying solely on the company’s internal testing processes.

Shocking Fact: Studies have found that about 25–45% of bottled water is actually repackaged tap water.

2. Plastic Bottles Can Contaminate Water

Although bottled water may seem purer, the bottles themselves can be unhealthy for you. Many plastic water bottles are made from polyethylene terephthalate (PET). These can release antimony and bisphenol A (BPA) into the water, especially when they get hot or sit in storage for a while.

Potential Health Risks:

  • Antimony: Linked to stomach pain, diarrhea, and other gastrointestinal issues.
  • BPA: Associated with hormone disruption, reproductive issues, and increased risk of certain cancers.

Shocking Fact: If bottled water is left in hot environments (like in a car), it can cause chemicals from the plastic to leach into the water at a much higher rate, making it potentially more dangerous than tap water.

3. Bottled Water Contributes to Environmental Pollution

The main issue with bottled water is its aspect of harming the environment. Every year, billions of plastic water bottles are consumed. However, only a fraction is recycled, while most end up in landfills, oceans, and natural environments to promote pollution and wildlife harm.

Environmental Impact of Plastic Bottles:

  • Energy Use: The production and transportation of bottled water consume large amounts of fossil fuels.
  • Plastic Waste: Plastic bottles take hundreds of years to decompose, and in the meantime, they can break down into microplastics that pollute water sources and harm marine life.
  • Carbon Footprint: The process of manufacturing and transporting bottled water generates a significant carbon footprint compared to using tap water.

Shocking Fact: The production of one liter of bottled water requires 3 liters of water, making it an incredibly wasteful process.

4. Tap Water Is Held to Higher Safety Standards

Unlike what most people believe, tap water in most countries is safer than bottled water. Also, municipal water suppliers are bound by law to frequently test for contaminants and meet certain public health standards.

EPA vs. FDA Regulations:

  • The EPA mandates that water suppliers test their water multiple times a day for contaminants and make the results available to the public.
  • The FDA only requires bottled water companies to test their water once a week, and those results are not always made public.

Shocking Fact: Tap water is tested up to 400 times per month for certain contaminants, while bottled water might only be tested monthly or quarterly.

5. Bottled Water Can Contain Microplastics

Recent studies have found that vast amounts of bottled water contain tiny particles of plastic, called microplastics. In fact, it could be from the plastic packaging or even the process of bottling itself. Microplastics now constitute a widespread pollutant; they are now found in both tap and bottled water, though the concentration in bottled water is more often higher.

Microplastics in Bottled Water:

  • Microplastics can be harmful to human health, as they can enter the bloodstream and may carry toxic chemicals.
  • While research is still ongoing, there are concerns that long-term exposure to microplastics could lead to inflammation, cancer, or other health issues.

Shocking Fact: Some studies have shown that bottled water contains twice as many microplastics as tap water.

6. Bottled Water is Expensive And Not Always Worth It

This being the case, bottled water is at times not even better in quality compared to tap water. To boot, bottled water is most of the time 2,000 times more expensive than tap water.

Cost Comparison:

  • Bottled Water: On average, a gallon of bottled water costs around $1.22.
  • Tap Water: In contrast, tap water costs just $0.004 per gallon.

For the price of one bottle of water, you could fill thousands of glasses from your tap at home. Given the similar or even better quality of tap water, choosing bottled water can often be a waste of money.

Shocking Fact: Americans spend $16 billion a year on bottled water, despite having access to safe tap water.

Bottled Water Really Safer Than Tap Water?

7. Tap Water Contains Fluoride Which Is Beneficial for Dental Health

Differences of Note One of the most drastic differences between tap water and bottled water is fluoride. In most countries, the fluoride added to tap water has prevented dental cavities. Thanks to the public health measure taken years ago, cavities and other dental problems have been reduced by so much.

Benefits of Fluoridated Water:

  • Cavity Prevention: Fluoride strengthens tooth enamel and reduces the risk of cavities.
  • Affordable Dental Care: Fluoridated tap water is a cost-effective way to protect dental health, especially for low-income populations.

Many bottled water brands do not contain fluoride, meaning that those who rely solely on bottled water might be missing out on its dental benefits.

Shocking Fact: The CDC estimates that fluoridated tap water can reduce tooth decay by 25% over a person’s lifetime.
