Assessment of the impact of abattoir effluent on the quality of groundwater in a residential area of Omu-Aran, Nigeria
Background: Water pollution from abattoir efuents may create substantial environmental and public health
hazards. Available literature is scanty on the quality of groundwater located near abattoirs in tropical developing
countries like Nigeria. This study, therefore, accessed the impact of abattoir activities on the quality of groundwater in
Omu-Aran Nigeria.
Methods: A total of eighteen water samples were taken from fve privately own wells and one control well located
at varying distances and elevations to the abattoir. The physicochemical characteristics of the water were determined
using the standard methods. Data were analyzed using descriptive statistics and ANOVA.
Results: The mean values of parameters in the water samples collected from the studied wells ranged from
5.80±0.20 to 7.23±0.55 mg/L, 12.0±1.0 to 26.0±2.0 mg/L, 0.06±0.02 to 0.16±0.02 mg/L and 208.0±24.25 to
254.67±12.22 cfu/mL for dissolved oxygen, biological oxygen demand, lead and total coliforms, respectively. There
was a signifcant diference in the quality of water from the studied and control wells in the parameters except that of
total coliform. The quality of the groundwater improved with increasing distance from the abattoir.
Conclusions: Findings revealed that abattoirs have the potential to impact the quality of groundwater. Therefore,
careful consideration is required when choosing a location for siting new abattoirs. For existing ones, particularly
those close to residential areas, efective pollution control measures should be put in place to protect groundwater.
