IMPACT OF WASTE WATER ON IRRIGATION WATER QUALITY IN MINNA, NIGERIA.

Abstract

Irrigation water from two typical suburbs in Nigeria; namely Minna Abattoir and Maizube Farm were analysed to ascertain the impact of waste water on their quality. The parameters investigated include total dissolved solids (TDS), electrical conductivity (ECw), pH, temperature, turbidity, biochemical oxygen demand (BOD), chemical oxygen demand (COD) and some major cations and anions found in the waste water. The analysis was replicated three times for each of the sampled sites. The results obtained were compared with international irrigation water quality standards. The study revealed that there were no adverse effects of the discharge effluents on the receiving watershed, and thus did not impair negatively on the quality of the irrigation water.
