n: 1. water that has little or no salt dissolved in it.2. underground water, generally located near the surface, that does not contain a large amount of salt and from which most underground drinking water supplies are drawn.3. inland surface water, such as lakes, streams, and ponds, that is not salty.

n: Formation water with low salinity. Water is considered fresh when its low conductivity makes the interpretation of resistivity logs difficult. The salinity at which this becomes important depends on temperature and clay content, among other factors, but i

water with less than about 600 ppm total dissolved solids. Suitable for drinking.

total dissolved solids in a quantity of liquid.

TDS, conductivity test of ions in the water. The combined dry weight of dissolved materials, both organic and inorganic, expressed in ppm that are contained in the water.
