ABSTRACT
A combined iso-potentiometric mapping and hydrochemistry study was conducted in the Walini urban area to assess quality suitability of groundwater for domestic other purposes regarding Walini’s development. The direction flow is northeast-southwest, based on observations from 22 water tables between 2022 2023. Groundwater samples obtained dug wells, bore springs were analysed determine physicochemical parameters (EC pH) concentrations major ions. result indicates that freshwater. It contains calcium (Ca2+), magnesium (Mg2+), sodium (Na+ ), potassium (K+ bicarbonate (HCO3-), chloride (Cl-) balancing levels. Piper diagram shows classified into calcium-magnesium-bicarbonate-chloride as dominant facies. Gibbs diagrams reflect hydrochemically controlled by lithology. Compared World Health Organisation’s (WHO) standards, appropriate drinking uses supporting However, compared shallow (4-20 m), deep (beyond 104 m) middle unconfined aquifers (between 35 m 73 higher. This because are vulnerable urbanisation. If current trends continue, management strategies protection would be critical sustainability.
