groundwater quality major ions arid climate Midyan Basin Saudi Arabia

The Midyan Basin is characterized by arid climate with rare surface water flow. Groundwater
is the main water resources in this region. In order to evaluate their suitability for drinking,
domestic and irrigation purposes, chemical characteristics of groundwater in the Midyan
Basin (northwestern Saudi Arabia) have been investigated and evaluated. A total of 72 water
samples were collected from different wells and analyzed for hydrogen ion concentration,
total dissolved solids, electrical conductivity, total hardness, Ca2+, Na+, Mg2+, K+, Cl-,
HCO3-, NO3- and SO42-. To understand quality of groundwater and their suitability,
chemical indices like sodium percentage, sodium adsorption ratio and salinity values have
been calculated using analytical techniques. From traditional Piper diagram for water
classification, the water quality is placed at Na+-Ca2+-SO42--Cl- type. According to the
results of electrical conductivity and sodium adsorption ratio, 37% of the studied samples
are regarded as highly saline, while 63% of them are classified as very highly saline. As
per the Arab Gulf and international standards, such waters are not suitable for irrigation
under normal condition and further action is required to remediate such problem by salinity
control. Sodium content in 24% of the studied samples is regarded as high that can’t be used
for irrigation purposes for any soils. Thus high level of salinity, sodium adsorption ratio and
sodium percentage in most water samples have made them unsuitable
