Bottled Water vs Tap Water
There are some significant differences between bottled water and tap water. Tap water is regulated by the Environmental Protection Agency (EPA), whereas the bottled water industry is overseen by the Food and Drug Administration (FDA). Tap water is subject to stricter regulations and is generally cheaper than bottled water. In some instances, bottled water companies use tap water for their products, resulting in the same quality for both types of water.
What is Tap Water?
Tap water comes from reservoirs and is supplied to homes through pipes. It is always regulated by the EPA, which sets government standards for tap water quality. The EPA does not allow coliform bacteria in tap water and requires filtration if water is taken from the surface of a pond, lake, or stream. Tap water must also be tested for toxic chemicals like phthalate and undergo rigorous testing for pathogens. One of the main advantages of tap water is that it is available for free or at a very low cost, aside from a minimal annual water tax.
What is Bottled Water?
Bottled water is sold in plastic bottles and is available for purchase from stores. It is regulated by the FDA, which does not oversee bottled water sold within a single state. Government standards are not set for bottled water, and the FDA allows coliform bacteria in bottled water. Filtration is not required for bottled water taken from the surface of a pond or river, and the FDA has not made filtration mandatory in such cases. Bottled water is not tested for toxic chemicals like phthalate or for the presence of germs. It is generally more expensive than tap water.
Key Takeaways
- Tap water is regulated by the EPA and is subject to stricter regulations than bottled water, which is overseen by the FDA.
- Tap water must be filtered and tested for toxic chemicals and pathogens, while bottled water does not require the same level of testing.
- Tap water is generally cheaper and more accessible than bottled water, which must be purchased from stores.
