Classification of saline water Global classification of water based on the salinity


Below table can be used to compare the values obtained from an Electrical conductivity  (EC) meter. If you want to know how to measure your soil for salinity, please visit our Soil sampling and testing tutorial

Below table shows a general classification of saline water, based on the electrical conductivity (EC, in dS/m). In this table, EC in dS/m is converted to equivalent concentrations in EC in μS/CM,  sodium chloride, parts per thousand, parts per million, magnesium chloride per litre.

Wadden sea water - ~40 dS/m
