【 摘 要 】

1) across all locations indicating the occurrence of saline water ingression in groundwater samples, especially during the dry spell. The increasing K+, Na+, and Cl– characteristics of the groundwater and calculated ionic indices values indicated the influence of seawater intrusion. However, total hardness values showed that the samples were very soft in nature. Irrigation water quality suitability, as indicated by sodium adsorption ratio (SAR), permeability index (PI), and percentage sodium (PS) varied with seasons and location, showing that water will cause soil deterioration and poor crop performance if intensively used for irrigation without proper precautions.
