Total Dissolved Solids (TDS) refers to the total concentration of dissolved substances in water, including minerals, salts, and other impurities. The TDS level of water is measured in parts per million (ppm) or milligrams per liter (mg/L). The safe TDS level for bathing and washing clothes depends on various factors and is not specifically regulated by a single standard. However, there are some general guidelines to consider:
Bathing: The TDS level of water used for bathing is not typically a health concern, as you are not ingesting the water. TDS levels up to 500 ppm are generally considered safe for bathing purposes. Many municipal water supplies fall within this range. Higher TDS levels may not pose immediate health risks, but they might cause skin dryness or irritation over time due to the presence of minerals.
Washing Clothes: Like bathing, the TDS level of water for washing clothes is generally not a major concern for health. TDS levels up to 500 ppm are safe for laundry purposes as well. In fact, some detergents work more effectively with slightly hard water (higher TDS levels), as the minerals can help enhance the detergent's cleaning action.
Keep in mind that the TDS level is just one aspect of water quality. Water with a high TDS level might have an unusual taste or leave mineral deposits on fixtures and clothes. Water softeners or treatment systems can be used to reduce TDS levels in the water, but it's essential to balance the mineral content and not remove beneficial minerals entirely.
If you are concerned about the quality of your water for bathing and laundry, consider getting your water tested by a certified laboratory. Local water authorities or private water testing companies can provide more specific information about the TDS and other parameters in your water supply, helping you determine if any action is necessary to improve its quality.
