الملخص EN

This study was carried out to analyse groundwater quality for irrigation purpose in Mitrid City.

Fifteen samples from different sites of selected study area were collected and analysed for major anions and cations.

The suitability of the groundwater for irrigation were evaluated based on the TDS, EC, Sodium Absorption Ratio (SAR), Kelly’s Ratio (KI), Sodium Percentage (Na%), Soluble Sodium Percentage (SSP) and Permeability Index (PI).

The calculated parameters show that the majority of the groundwater samples are suitable for irrigation uses.

According to the Gibbs diagram, groundwater in the study area is dominated by evaporation followed by rock–water interaction process.

Also the Wilcox diagram classify the groundwater as good to doubtful category.

Generally, the groundwater in the study area is good for irrigation purposes.
