    Water is fundamental to every life component on earth, including humans, animals, and plants. It is a component of food, an essential source of mineral nutrients, and plays a key role in various metabolic processes, hence underscoring the need for safe drinking water. However, research on the composition of water in cities like Nairobi, with its rapidly growing population, remains very limited. Therefore, there is a need to assess the water quality determining components in different years and seasons. The study assesses seasonal variations in water quality parameters, including pH, turbidity, conductivity, iron, manganese, total dissolved solids (TDS), and determines their safety for consumption. Nairobi River was sampled purposively since it is the main river, and the borehole, tap, and bottled water were sampled randomly in the selected study area. A total of 192 samples were collected from multiple locations representing each water source. The study employed standard laboratory methods for water quality analysis. Data were analyzed using SPSS, with a one-way ANOVA and post hoc Tukey tests to identify statistically significant differences between sources and seasons (α=0.05). The study revealed significant differences in water quality parameters in the different water sources: tap, borehole, river, and bottled water
