The chemical quality of water is characterized by concentrations of 

 dissolved ions and suspended solids. The amount or occurrence of these 

 constituents in water govern how the water may be utilized and thus may be 

 considered as criteria for water quality and water use. The chemical quality 

 of streams in coastal Alabama is often characterized by the mineral content 

 (Tables 41 and 42). The total mineral content in water is referred to as 

 total dissolved solids (TDS). In coastal Alabama most streams have a TDS of 

 100 milligrams per liter (mg/1 ) or less. The amount and type of dissolved 

 solids determines water hardness, what type of industrial processes it is 

 suitable for, and what chemicals or chemical reactions it must undergo before 

 achieving desirable properties for particular uses.
