Total Dissolved Solids (TDS)
The sun of all the substances, organic and inorganic, dissolved in water
What are the major ions in natural waters?
Ca2+, Na+, K+, NH4+, SO42-, Cl-, NO3-
Salinity
Is the degree of mineralization of water
Salinity helps govern….
Along with T and pressure, salinity helps govern physical properties of water, like density and heat capacity. Salts can be bad for freshwater plants and animals, and an overload of salts occurs when evaporation is high
Water density _____ with salinity
Increases
The higher the salinity, the ________ the DO concentration
Lower
Water-quality parameters
Salinity, dissolved solids, and electrical conductivity
