Description
Background
Water pollution from abattoir effluents 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 five 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 significant difference 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.
