The pH of drinking water should be neutral, but it can vary from region to region.

Clean spring water is optimal, and this is the quality we want to obtain from our tap water.

As a rule of thumb, the pH of drinking water should be be around 7.2 to 7.5, matching the pH balance in the human body (No wonder, since our body is about 70% water)

pH of Drinking Water in our environment


pH of Drinking Water

In civilized countries, typically we don’t find acidic, or alkaline water beyond the accepted healthy limits in the municipal drinking water. However, significant variations in the water pH can be found in natural water from various sources that have not been treated.

It is important to know about the pH of water, because this affects its quality

For instance:

Acidic water:

This can be found in lakes, rivers or underground water. It is generally caused by nearby industries or communities which discharge their waste into the environment without any previous treatment.
Acidic water can contain toxic chemical substances, animal or human excrements, and it’s definitely hazardous for our health.

If you want to use water from any natural source, you should have it analyzed first and use an appropriate water purification device.
As I mentioned, in normal cases you don’t find unhealthy levels of acidic water coming from the municipal distribution system. Some products used in the water treatment can cause acidity, but not to unhealthy levels. However it’s always a good idea to test the water you drink, just to be sure.

Alkaline water:

There are places in nature are richer than other in calcareous stones or other minerals easily dissolved. Natural water in these cases becomes alkaline.

  • When it contains an increased amount of Calcium and Magnesium, water is known as hard water.

This type of water is very common to be found in tap water and while it’s not a major health threatening when drinking it.
The hard water however is not a good friend to our skin when bathing and showering. It is also detrimental for household appliances, as well for industrial use. There are a lot of methods to soften it including advanced water filters.
