Comparative water quality analysis for road runoff water, case-study Kenya
A report that compares water quality parameters of water harvest from roads, rock catchment, river, borehole and a shallow well. It concludes that the water quality of road runoff is better off compared to other sources, only issues along road being exceeding values of high iron and turbidity. This can be prevented/treated with appropriate measures. Overall there is huge potential of road runoff also to be used for domestic use.
