Portable Multi meter can be used to determine the salinity of groundwater (Afroza et al., 2009).

Conductivity Meter can be used to determinate ground water salinity.

Hi, you can find somethings from this link:

Mohsin J. Nasir

it can be measured the salinity of soil using sequential extraction procedure(SEP).

Omar Ali Al-Khashman

Conductivity Meter can be used to determinate ground water salinity in the field, but in lab it can measured by analysis the water samples and determined the ions in sample and determine Total Dissoloved Solids (TDS), Total Hardness(TH) Sodium Absorption Ratio (SAR), Carbonate analysis and sodium analysis.

Rahma Ayadi

two methods are used to determine salinity of groundwater TDS: in situ method and laboratory method

- by the portable EC tester the conductvity value is used to determine the saliny by the formula :TDS= EC * 0.75

- the laboratory method: The total dissolved solids (TDS) are measured in the laboratory by evaporating 100 ml of water sample for 24 h at 105˚C.

by using conductivity meter

Respected Rahma Ayadi,

Good evening. I am thankful to you for

your response. Is there any difference between TDS and salinity of the groundwater or they are same. With best regards

Sincerely

Agreeing with each other

Dear Mr.Saha,

we considered the groundwater salinity as TDS (Total Dissolved Solids) which is measuured in lab by evaporating 100 ml of water sample.

Best Regards

The measure salinity of groundwater it depend in two method, the first in field measurement (situ method ) it determined by measurement of Electrical conductivity (EC) by the portable EC tester conductivity value it used to determine salinity by the formula: TDS= EC * 0.64. The method in the laboratory it determine by TDS are measured in the laboratory by evaporating 100 ml of water sample for 24 h at 105˚C.
