Abstract
Groundwater has been assumed to be naturally clean and needs no purification. This study determined groundwater quality in Enugu, Southeastern Nigeria to determine if it is safe for human consumption. Quasiexperimental design was adopted for the research while inferential and geostatistic tools were used in data analysis. Analysis of Variance (ANOVA) was used to compare the mean values of the water quality, with all parameters significant except two. The Principal Component Analysis (PCA) showed discernible spread pattern of the sampled parameter. The Piper Plot revealed mixed CaNaHCO3 (Calcium-Sodium-Bicarbonate) and NaHCO3 (Sodium-Bicarbonate) types. The Stiff Plot revealed variation in water type showing that 60%, 17% and, 23% are NaHCO3 type, CaNaHCO3 type and other types, respectively. The Gibbs Plot reveals that the groundwater of the study area is influenced by rock weathering and precipitation. The Durov plot reveals a high pH signifying water acidity making it questionable for drinking. The findings reveal that groundwater quality in the study area is mainly influenced by natural factor, and generally unfit for drinking. The study recommends continuous monitoring using software technologies for effective management of groundwater quality and internet based technologies for disseminating water quality status to the public.
