Does Potable Water Mean Pure Water?

Potable water does not necessarily mean pure water. While the treatment process can remove many contaminants, it cannot guarantee that all of them have been removed or that the water is safe to drink. Although it meets certain standards set by local authorities and other organizations.

What Is Potable Water?

Potable water is drinking water that has been treated to a safe level for human consumption. This can include both surface and ground sources, such as lakes, rivers, wells, and aquifers. The treatment process typically involves disinfection to remove pathogens and other contaminants, as well as the addition of chemicals such as chlorine or fluoride in order to make the water safe.

What Is Pure Water? (H2O)

Pure water, which is also known as H2O, contains only two elements: hydrogen and oxygen. It does not contain any other impurities or contaminants. However, it is very difficult to obtain pure water in nature because it tends to become contaminated with pollutants from the environment.

Where To Get Pure Water? (H2O)

The only way to get pure water is through distillation, reverse osmosis, deionization, or ultrapure filtration. These processes involve filtering the water multiple times in order to remove all impurities and contaminants. This is typically done in a laboratory setting, where the results can be tested for purity.

Why Is It Called Potable Water?

The term “potable water” is used to describe water that is safe for drinking and other human uses. The word potable is derived from the Latin potare, meaning to drink.

Examples Of Potable Water

  • Bottled Water
  • Ground Water (Well Water)
  • Surface Water (Lakes, Rivers, Streams)
  • Tap Water From Municipal Supplies
  • Rainwater Collected In Cisterns

Characteristics Of Potable Water

  • Odorless and tasteless
  • Colorless
  • Free of bacteria, viruses, and other contaminants
  • Meets criteria set by regulatory bodies

Potable Water Standards

  • Under the United States Environmental Protection Agency’s (EPA) Safe Drinking Water Act, drinking water is required to meet standards set by the EPA
  • The World Health Organization (WHO) has established global guidelines for safe drinking water, including criteria for bacteria and other contaminants that must be met to ensure safety

What Is Potable Water Used For?

  • Drinking
  • Cooking
  • Cleaning and hygiene purposes, such as brushing teeth, washing hands, and preparing food
  • Watering plants or other outdoor activities that require water use.
  • Irrigation and other agricultural purposes.

Threats To Potable Water

Pollution From Industrial Activities: From factories polluting rivers and streams to agricultural run-off leaching into groundwater, industrial activities are often a major source of water contamination.

Pesticides And Other Chemicals: Pesticides and fertilizers used in agriculture can seep into water supplies, polluting drinking water with toxic chemicals. Other hazardous chemicals such as those used in industry or from leaking gas tanks can also cause contamination.

Poor Sanitation: Poorly maintained sewage systems and inadequate waste disposal lead to pathogens entering the water supply, which is a major health threat.

Over-Extraction Of Groundwater: In some areas of the world, people are pumping too much groundwater for agricultural or industrial use, leading to water scarcity.

Climate Change: As the climate changes, some areas may experience more frequent droughts or floods, which can reduce the availability of safe drinking water. Warmer temperatures can also lead to algal blooms in lakes and rivers, making them unfit for drinking.


What Water Is Conductive Potable Or Pure?

Pure water is not conductive because of its lack of ions or impurities, whereas potable water has conductivity due to its chemical composition.

What Is Non-Potable Water?

Non-potable water is a term used to describe any water that, for various reasons, is not suitable for drinking. It is usually recycled water that is considered unsafe for consumption.

Why Is Distilled Water Not Potable Water?

Distilled water is actually safe for drinking, but it is not considered a palatable option due to its lack of taste. Distillation processes remove virtually all impurities from the water by boiling it and then condensing the steam back into liquid form. The result is pure, tasteless water; however, some essential minerals found in drinking water are also removed during the distillation process. For this reason, distilled water is not considered potable water.

Is Rainwater The Only Pure Potable Water?

No, rainwater is not the only source of pure potable water. There are many ways to purify and make water safe for drinking, such as boiling, distillation, filtration, chemical treatments like chlorine and ozone disinfection, and ultraviolet light treatment.

How Clean Must Water Be To Be Considered Potable?

  • Potable water should have no more than 500 parts per million of dissolved salts and should contain no known disease-causing organisms.
  • Levels of microorganisms such as E. coli and Coliform should be low.
  • Water should be free of chemicals and other contaminants that may pose a health risk.
  • Depending on the jurisdiction, potable water needs to meet additional standards in terms of odor, and clarity.

Why Can’t We Drink Pure Water?

  • Pure water on its own does not contain any of the essential minerals and nutrients that our bodies need to function optimally.
  • Drinking pure water can lead to an electrolyte imbalance in the body, which can cause nausea, vomiting, headaches, and other unpleasant symptoms.
  • Pure water has no flavor, so it may be difficult to drink enough of it to stay hydrated.


While pure water is safe to drink in small quantities, it should not be relied on as the main source of hydration. It is recommended to drink filtered water that contains essential minerals and nutrients and is free from contaminants. By choosing the right option, you can stay healthy and hydrated.
