The physico-chemical evaluation of pollutants in water sample from Alau Dam, Borno State was conducted in July, 2014. The parameters (turbidity, temperature, total dissolved solid (TDS), electrical conductivity (E.C) and pH were determined using standard procedures. Also heavy metals (Cd, Cr, Cu, Mn and Zn) were determined by Flame Atomic Absorption Spectropheotometry (FAAS). The results of the analysis showed that temperature was 28.8oC, total dissolved solid (TDS) was 63ppm, electrical conductivity (E.C) was 130s/cm, turbidity was 78.0NTU and pH was 7.5. While the concentration levels of heavy metals were Cd (0.02)mg/l, Cr (0.15)mg/l, Cu (0.48)mg/l, Mn (0.07)mg/l and Zn (0.28)mg/l. The results showed presence and concentration levels of all the parameters analyzed and were within the maximum levels set by WHO and NAFDAC, except for Cd and Cr that exceeded the permissible limits which are a cause of concern, as consumption of water and other aquatic life from the study area may cause health hazard to human. Based on the findings, close monitoring, involving human heath risk assessment in relation to environmental pollution of Alau Dam is recommended.
