In its raw state, saline water cannot be used for many of the purposes we need water for, such as drinking, irrigation, and many industrial uses. Slightly saline water is sometimes used for similar purposes as freshwater. For example, in colorado, water having up to 2,500 ppm of salt is used for irrigating crops.
