ABSTRACT:

Assessment of the level of some heavy metals; arsenic, lead, cadmium, iron, manganese, and chromium in ground water of Gombe State University and its Environs was carried out using Inductively Couple Plasma Atomic Emission Spectrophotometer (ICP-AES) model 2000DV for three months. The results of the analysis in mg/l show that arsenic ranged from 0.050±0.005 to 0.150±0.005;  lead  ranged from 0.001±0.001 to 0.015±0.002; cadmium ranged from 0.000±0.000 to 0.004±0.002; iron ranged from 0.006±0.004 to 4.865±0.745; chromium ranged from 0.002±0.001 to 0.003±0.002; and, manganese ranged from 0.003±0.001 to 3.066±0.130. Arsenic concentration was found to be above WHO and SON maximum permissible limit for portable water for all the sampling points. Lead was above WHO and SON maximum permissible limit only in sampling point AU2. Iron and manganese were outrageously higher than WHO and SON in sampling point AU2.It was concluded that the ground water of Gombe State University and its Environs is contaminated with arsenic and is not good as portable water
