Abstract:
Abstract Mau Forest in the upper reaches of the Mara River basin has recently undergone
increased forest destruction followed by human settlement and agricultural activities. These
anthropogenic activities may be contributing nutrients and heavy metals, ultimately polluting
the river water and eventually Lake Victoria water hence damaging these aquatic
ecosystems. This study sought to establish the effect of anthropogenic activities and season
on the water quality of the Amala and Nyangores tributaries of the River Mara in Kenya.
Pristine springs in the Mau Forest were used as reference sites. Water samples were
analyzed for pH, temperature, conductivity, nutrients, selected heavy metals, and selenium.
The mean range of the parameters measured from sites along the tributaries was pH 5.44–
7.48 and that for conductivity was 20–99 μS/cm while the mean range of nutrient levels …
