|Abstract: ||Background: Groundwater quality is among the most important environmental issues as a result of heavy metals
contamination from anthropogenic sources. Concentrations of heavy metals in hand-dug wells from Ejisu-Juaben
Municipality were studied to understand the levels of heavy metals and their source of pollution.
Results: The results show that the average abundance of heavy metal concentration in the groundwater samples
are in the order: Fe > Zn > Mn > Pb > Cu > Cd. The non-carcinogenic risk indicates that the groundwater is safe and
therefore poses no health risks; however, the carcinogenic risk exceeds the acceptable limit of 10−6. Principal component
analysis extracted two components, which explained 64.24 % of the total variance. Cd suggests that 63 % of the
samples are highly polluted (Cd > 3), whereas HPI indicates that all the samples are above the critical limit (HPI > 100).
Conclusion: Our findings concluded that lithogenic and anthropogenic activities are the main source of contamination
influencing the water quality.|
