Abstract-Dr. Abubakar Sola Saraki Memorial abattoir is a new abattoir constructed to ensure meats are prepared in hygienic environment and safe guard health of citizenry. Its operation is belief to be impacting greatly on the environment through discharge of animal wastes into environmental media. This study aims at finding out physiochemical parameters/ quality of the stream water where the abattoir effluents are discharged. Water samples were collected in three different locations (Upstream, Midstream and Downstream) along the course of the stream. Laboratory analysis were carried out on the water samples collected using Atomic Absorption Spectrophotometry (AAS) technique. The parameter considered; pH, Temperature, Total Dissolve Solid (TDS), Electrical conductivity (EC), and heavy metals (Zn, Pb, Cu, Ca and Cr).
Results: The result for heavy metals revealed; Zn (0.08- 0.16mg/l), Pb (0.0mg/l), Cu(0.02-0.05mg/l), Ca(0.04-1.80mg/l) and Cr(0.0mg/l) all fall within WHO maximum permissible limit of Zn(3.0mg/l), Pb(0.0145mg/l), Cu(1.0mg/l), Ca(180mg/l) and Cr(0.05mg/l). The pH, EC, Temperature and TDS were found to be within the two standards. However, the turbidity values of 11-81NTU were found to be above WHO and SON standard of 5NTU and 15NTU respectively. From the survey, very high turbidity could be an indication of high microbial load which renders the water not suitable for domestic and industrial use. Strict hygienic management of the abattoir waste needs to be enforced by concerned authorities.

I. INTRODUCTION

Livestock products are vital food for the growing world population. However, poor management of the resultant wastes from abattoirs especially through run off and its discharge into various water bodies such as stream, rivers, lakes and oceans has contributed greatly to environmental pollution.
Continuous discharge of wastes into environmental media signals great danger for the organismal survival, therefore this called for monitoring, protection and management of water resources. Increasing activities of man along the water bodies globally has become a phenomena calling for attention [15, 31].
