Abattoir wastewater has a complex composition and very harmful to
the environment. There is always need for reduction in the impact of
natural and most especially anthropogenic pollution to enhance water
quality, food safety and sustainable development. Physico-chemical and
microbial properties analysed using standard laboratory procedures
were temperature, pH, conductivity, turbidity, total solid (TS), total
dissolved solid (TDS), total suspended solid (TSS), dissolved oxygen
(DO), acidity, alkalinity, total hardness, calcium and magnesium
hardness, chloride, iron and nitrate. Temperature ranged from 28.04-
29.12C, pH between was 7.67-8.01, Alkalinity is 0.45 mg/l, TS, BOD
and TSS were 700 mm/l, 48 mm/l, 500 mm/l, DO is 2,100 ppm.
Holistic outputs of the investigation revealed various water samples
were contaminated with E. Coli and other enteric bacteria. The
presence of coliform staphylococcus aures indicated the presence of
microorganisms which are associated with water borne disease.
