The salinity level in drinking water, often referred to as the “total dissolved solids” (TDS), is a crucial factor in determining its quality and taste. The TDS in drinking water is measured in parts per million (ppm) or milligrams per liter (mg/L). The World Health Organization (WHO) suggests that the TDS level in drinking water should ideally be below 600 mg/L for best taste. However, this guideline is not a strict limit but rather a recommendation for acceptable quality.
In general, TDS levels between 300-500 mg/L are considered good, while levels above 1000 mg/L may be unpalatable to some individuals due to the noticeable taste. Higher TDS levels can also indicate the presence of other contaminants, such as minerals, salts, and metals, which can affect the water’s safety and taste.
It’s important to note that while TDS is a useful indicator of water quality, it doesn’t provide a complete picture. Other factors, such as pH, presence of specific contaminants, and microbiological safety, also play a role in determining the overall quality of drinking water.

The salinity or total dissolved solids (TDS) in drinking water is a measure of the combined content of all inorganic and organic substances dissolved in water. These can include minerals, salts, metals, cations, and anions. TDS is typically measured in milligrams per liter (mg/L) or parts per million (ppm).
The TDS level in drinking water can vary depending on the water source and treatment processes. Natural sources like wells, springs, and rivers may have different TDS levels based on the geology and environment they pass through. Human activities, such as agriculture, industry, and urban runoff, can also contribute to higher TDS levels in water.
The taste of water is affected by its TDS level, with higher levels often resulting in a more pronounced taste. However, the taste perception of water can vary widely among individuals, and some people may prefer water with higher TDS levels, such as mineral water.
While TDS itself is not a health concern, high levels of certain dissolved substances can affect water quality. For example, elevated levels of certain ions like sodium, chloride, or sulfate can make water unsuitable for drinking, especially for individuals with specific health conditions like hypertension or kidney problems.
Regulatory bodies like the World Health Organization (WHO) and the Environmental Protection Agency (EPA) provide guidelines for acceptable TDS levels in drinking water. These guidelines are based on taste considerations and do not necessarily reflect health risks associated with TDS.
