What does brackish mean?

Brackish is a term used to describe water that contains more dissolved minerals (see total dissolved solids) than normally acceptable for municipal, domestic and agricultural uses. It has a higher amount of dissolved solids than fresh water but not as high as saltier types such as seawater.

Brackish water includes concentrations of total dissolved solids (TDS) ranging from 1,000 to 10,000 milligrams per liter (mg/l).
