The multiple industrial, domestic, agricultural, medical, and technological applications of heavy metals have led to their wide distribution in the environment, raising concerns over their potential effects on human health and the environment. This work focused on the determination of manganese, chromium, zinc, cadmium, arsenic, mercury, iron and lead concentrations in Abakpa, Iva Valley, and Transekulu Rivers which are close to residential areas in Enugu, Nigeria. The analysis were carried out using atomic absorption spectrometer (AAS). All the heavy metals tested in the three studied locations exceeded the different drinking water limits except zinc which was below secondary drinking water standard of 5.0 mg/l. The levels of mercury and zinc were significantly higher in Abakpa River (0.57 ± 0.112 and 0.881 ± 0.0015 mgl-1 respectively). Iva valley showed higher levels of manganese, chromium, iron and arsenic compared to other rivers studied. The presence in these metals in the water sources are a great risk to humans and the environment.

The levels of some physicochemical parameters and some selected heavy metals from boreholes and wells water were assessed in Dutse District area of Jigawa. Samples were collected randomly from different sampling sites and were analyzed using standard methods of analysis. The result shows that pH had a mean level of 7.8 + 1.45, conductivity mean level was 532.4 + 28.64 MSCM-1. The mean total hardness was 160.5 + 0.7, Turbidity had a mean level of 1.7 + 0.22 NTU, chloride had a mean level of 69.91 + 21mg/l and total dissolve solid TDS had a mean of 292.9 + 21.14mg/l. heavy metals analyzed include copper, chromium, lead, nicked and zinc using Hitachi Z – 8100 Atomic absorption spectrometer and their mean levels are 0.31 + 0.2mg/l, 0.11+ 0.01mg/l, 0.14 + 0.007mg/l, 0.20 + 0.007mg/l and 0.09 + 0.002mg/ls respectively. The result indicates that the physicochemical parameters and the heavy metals are within the maximum allowable levels set by WHO and NDWQS 2011.
