What is the Normal TDS Level of Drinking Water?


The TDS stand for total dissolved solid, it is the measuring level used in drinking water. The TDS level of the water is an important measure to determine the drinkability of the water, the TDS level in water differs from one place to another and it comprise of various elements such as calcium,  magnesium, potassium and sodium.

Sources of TDS in water

The water of different places are different in composition and this difference depends on the geographic conditions and the other environmental or man-made causes. The composition of amount of minerals get increased sometimes and this imbalanced increase lead to difference in TDS level of the water, whereas many a times the mineral composition of water changes due to human intervention such as the establishment of industrial plants and the release of chemically induced water in environment. The imbalanced increase of TDS in drinking water due to certain chemicals and minerals in water makes water inappropriate for drinking.

Effect of TDS

TDS effects water in different ways, although the presence of TDS in water is always there but the increase of TDS in water is the matter of concern, there are various effects of increased level in TDS of drinking water:-

  • Taste and odour of the water gets chance with the increase of the TDS level in the water. The water becomes salty, bitter, or metallic and it can make the water less appealing for drink.
  • Various skin and hair related issues appears due to higher level of TDS in water, the skin gets dry, irritation may occur or hair becomes rough.
  • The high level of TDS may leads to many hazardous diseases the increase in TDS also shows the rise of contaminants in the water, such as heavy metals, nitrates, or certain minerals that, in excessive quantities, can pose health risks.
  • The water having high level of STD is less hydrating in comparison to that of less TDS level water.

The Normal TDS Level of Drinking Water

The measure of normal TDS level in drinking water may vary from preferences to the local regulations, many a times people use to prefer the TDS level as per the preference provided by their consultant or the local regulation. Well, followings are the general guideline for measuring the normal TDS level.

  • EPA Guidelines: The United States Environmental Protection Agency (EPA) had suggests that the TDS levels of drinking water should ideally be below 500 milligrams per litre (mg/L). The water having TDS levels in this range is typically considered to be safe for drink.
  • Preference: People use to have different preferences as per their needs, many a times we use to prefer the TDS level suggested by our consulted doctor. Some people prefer water with lower TDS levels (below 300 ppm) as it tends to taste purer and cleaner. Whereas the water with higher TDS levels may have a detectable taste due to the minerals and salts dissolved in it.
  • Mineral Content: The TDS level in water is the primarily indicator of the mineral contents present in water. Higher level of TDS are often associated with the hard water, which contains elevated concentrations of minerals like calcium and magnesium.
  • Local Variations: Geographic conditions of different places plays greater role in determining the presence of TDS. Water sources and quality can defer from one location to another, so what is considered "normal" in one area may not be the same in another. Some regions naturally have higher TDS levels in their water supply due to geological factors whereas another area might not have that same level of TDS. So do prefer to follow the local regulations provided in your location regarding the TDS level, or setup an RO water plant small or big as per your need.

Well, TDS level in water is the way to determine the drinkability of the water and above mentioned ways are the standards by following which you may find the normal and perfect TDS level of drinking water in your geographical location. Now you need not to worry about the TDS level of your water, feel free and use the above mentioned ways to find the normal TDS level of water in your geographical location.
