“Water is the most critical resource issue of our lifetime and our children’s lifetime. The health of our waters is the principal measure of how we live on the land.” – Luna Leopold According to the U.S. Environmental Protection Agency (EPA), the recommended pH range for drinking water is 6.5–8.5. The Total Dissolved Solids (TDS) level should be kept below 500 mg/L (500 ppm). For non-drinking water such as spring or bottled water, TDS should not exceed 1000 mg/L (1000 ppm). According to the EPA, WHO, and EU, pH and TDS levels typically have no direct health effects on consumers. However, they are critical water quality indicators, as they influence how water interacts with its surroundings. These interactions can affect the appearance, taste, and odor of drinking water and may signal problems in the water supply system that could impact public health.

Changes in TDS and pH levels can affect the texture and taste, making the water less suitable for consumption. Scientific research has revealed several reasons why monitoring TDS and pH in drinking water is essential: *Taste – High TDS levels can make water taste salty or bitter. *Health Concerns – While high TDS alone may not harm your health, elevated levels of harmful substances like lead or copper can cause illness. *Cooking – TDS levels above 1000 ppm can alter the taste of food during cooking. Q: What is the best TDS level for drinking water? A: A TDS level between 50–500 ppm is generally considered ideal and safe. Levels below 50 ppm are considered excellent-quality drinking water. Note: Water under 80 ppm is classified as soft; 80–160 ppm is moderately hard; and above 300 ppm is considered very hard. Q: Is a low TDS level bad or harmful to health? A: A TDS level above 1000 ppm is unsafe for drinking and should be avoided. 𝐎𝐭𝐡𝐞𝐫 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬: TDS and pH play a vital role in making nutrients soluble for plants in hydroponic systems.
