The water quality research investigation focuses on ten chosen boreholes in Naivasha sub-county. Within this examination, the chemical, physical, and biological characteristics of the water will undergo measurement. The concentrations of parameters will be assessed against the standards set by the World Health Organisation (WHO) and the National Environment Management Authority (NEMA). The project's results will provide insights into the present condition of water quality, identify potential contamination sources, and propose measures to enhance water treatment and distribution infrastructure.
