Chemometric Characterisation of Surface Water Quality in Uruan, Nigeria


Author(s): Imaobong Inyang Udousoro, Ndoto Etim Ikpeme

Abstract: Chemometric techniques were applied to surface water datasets collected form Uruan, Nigeria. Water quality index (WQI) and pollution index (PI) were employed to evaluate the pollution status of each station and parameter respectively. WQI ranged from 8 (Excellent for drinking) to 641(Unsuitable for drinking); 13 stations recorded excellent and 2 stations were unfit for drinking. PI ranged from 0.003 (Class 1, No Pollution) to 11.91 (Class 5, Seriously Polluted). The presence of total dissolved solids, Mn and Fe (Class 5) compromised water quality for domestic use. Five principal sources accounted for 81.329% of total variation which may be explained by natural mineralization, wash load of top soil from agricultural soils, mineral organic component, anthropogenic input from industrial activities and fossil fuel exploitation. Sampling stations were classified into six clusters; stations of excellent quality (Group 6) represented reference sites for future management of surface water resource.
