Abstract
Globally, safe drinking water is important and is fundamental to health, survival, and
growth. Well water sources are treated and managed for safe use in developed countries
like Germany whiles in developing countries like Ghana well water is assumed to be
free from all pathogenic organisms and consumed without prior treatment. Only a small
proportion of the populace have access to treated piped water across the globe including
Ghana of which residents of Atonsu Dompoase is of no exception. The closeness of a
landfill facility to well water sources have a potential of infiltrating the water and
causing health related problems like cholera, skin rashes and diarrhoea as alluded to by
residents of Atonsu Dompoase. The objective of this research was to assess the possible
effect of leachate percolation on well water quality at Atonsu Dompoase Landfill Site.
Concentrations of various physico-chemcial parameters including heavy metal elements
(Cd, Cr, Cu, Fe, Ni, Pb and Zn) and microbiological parameters (total coliform, TC and
faecal coliform, FC) were established in both leachate and well water samples. The
effect of distance of wells from the Atonsu Dompoase Landfill was also investigated.
Leachate and well water samples were collected from Atonsu Dompoase Landfil Site
and Atonsu Dompoase community, respectively. Results were subjected to statistical
evaluation using Analysis of Variance (ANOVA). The ANOVA was conducted with the
Genstat software. All analyses were conducted at a significance level of 5 %. TC and FC
counts; pH and electrical conductivity (EC) were significantly higher in well water
samples collected from Atonsu Dompoase vicinity than the Ghana EPA/GSB standards
and are of great concern to public health when the water from these wells is consumed
without prior treatment.
