The salinity of seas, oceans, hypersadine lakes and the Dead Sea is represented mostly by chlorides inland waters contain mostly carbonates and hydrocarbonates. Salts present in industrial wastewaters can influence the quality of underground and surface water. A variety of microorganisms indicate the presence of salts in water. For example, the diatom Thalassiosire fluviatilis is an indicator of potassium salts in wastewaters.
