Groundwater Geogenic and Anthropogenic Assessment of Organic and Inorganic Contaminants within Three Major Metropolies in Enugu

Abstract

This study assessed the impact of increased industrialization and population within three major metropolis in Enugu, namely Abakpa, Emena, and Independence Layout by analyzing 60 water samples and 10 shale samples. Inventory of Dumpsites were done and categorized into domestic, industrial, commercial and hazardous wastes. Pollution load indices analysis such as Heavy metal pollution index (HPI), Heavy metal evaluation index (HEI) and Degree of contamination (C_deg) categorized the groundwater quality in the study area into low, intermediate and high contamination. The multivariate statistical analysis extracted three anthropogenic diagnostic factors controlling the chemistry based on the parameter associations. The XRD analysis shows that influence of geogenic factors in groundwater contamination within the study area is very minimal. None of the computed WQI fell within the excellent water quality within the stud. Generally 28.3% of the groundwater fell under the good water quality, 41.6% within the poor water quality, 20% within the very poor water quality and 10% within the unsuitable water condition.
