This study assessed the distribution of water quality for surface and groundwater samples collected within artisanal refining sites in Ohaji/Egbema local government area in Imo state. The sampling technique involved collecting ten groundwater and ten surface water samples around artisanal refining sites within the distances of 0-100m, 100-200m, 200-300m, 300-400m, 400-500m, Four control samples (two each for surface water and groundwater) were also collected at distances of over 10km from the refining sites. Some physicochemical parameters were analyzed, and water quality index were also calculated for difference distances based on measured physicochemical parameters and WHO standards using weighted arithmetic mean methods.
