Ground water is a large source of water for utilisation in the world. This resource is not easily
accessible to monitor its changes and its deterioration is not easy to reverse. In the current study,
physico-chemical parameters for groundwater for Kiwanja Market (KM) were analysed and compared to the
Kenya Bureau of Standards (KEBs) water quality. The pH, DO, temperature, turbidity, chlorine, iron, water
hardness, potassium and calcium were analysed. All the parameters studied were within the stipulated levels
except iron, chlorine and for samples from point C (Ebenezer Hostel). Turbidity for points A and C were above
the permissible levels of KEBs standards. The water from point A and C may require further treatment to allow
for domestic use. This analysis revealed to some extent a healthier system, though further analysis is needed
to support this assertion. Continuous monitoring of the groundwater source within KM should be taken on
regular basis to detect any changes and to sustainably maintain the quality of water within the required KEBs
water quality standards.
