Brackish Water

Brackish water is water that has a saltiness somewhere between freshwater and seawater. It typically contains between 0.5 and 30 parts per thousand of dissolved salts. This type of water is commonly found in estuaries, where freshwater from rivers mixes with salty seawater, and in some coastal aquifers. Brackish water is important for certain types of aquatic life and can be used for drinking and irrigation after proper treatment. Its unique salinity level makes it a transitional resource, requiring specialized methods for desalination if used for drinking supplies.
