Permissible TDS Range for Drinking Water
The US Environmental Protection Agency standard for safe drinking water required the TDS of this water to be equal to or less than 500 mg/L. In practical terms water of salinity lower then 1000 mg/L will be suitable for drinking. This water however may not be useful for irrigation of citrus fruit, streawberries and some other saline sensitive plants.
