Physico-chemical and Microbiological Qualities of Abattoir Wastewater in Egbu, Imo State, Nigeria

Abbattoir waste water is of a complex composition. When discharged without being treated, poses threat to human health and the environment. This practice common in Nigeria, worrisome.
 Objective: The aim this study was assess physico-chemical microbiological qualities from Egbu abattoir into ‘Otamiri’ river Owerri North local government area, Imo State, Nigeria.
 Methods: microbial quality wastewater studied. duration three months, June September, 2019. Sample collection done morning (8-10am) evening (4-6pm). A total thirty samples (30) were collected two sampling points, at place generation (Effluent source) point discharge (POE). Standard methods employed physiochemical effluent. microorganisms isolated included Escherichia coli, Salmonella, Staphylococcus, Aspergillus, Mucor, Listeria, Micrococcus Candida species. Total Heterotrophic Count (THC) effluent samples, source POE 8.51log10 cfu/ml 6.15log10cfu/ml respectively, Coliform (TCC) for same 6.77log10 4.56log10 respectively. Fungal (TFC) 5.19log10 4.18log10 Results further revealed that pH 6.58 while Point Entry 7.30. temperature both 25oC. Dissolved Solid values higher, having value 1400mg/L against 1000mg/L Entry. Also Biochemical Oxygen Demand (BOD) Chemical (COD) 5.10mg/L 8.58mg/L BOD COD 4.3mg/L 7.9mg/L respectively.
 Conclusion: Abattoir wastes are becoming major environmental challenge Otamiri River indiscriminately public concern. potential implications associated with discharging untreated environment thus, need adequate treatment ensure decontamination as well providing facility imperative.
