Assessment of Underground Water Quality Parameters of an Abandoned Abattoir.

Abstract

The problem of getting quality water for domestic purpose is increasing as untreated effluents are discharged on ground surface and percolate into underground water. The impact of effluent from Mokwa abattoir in Mokwa, Niger State on the physical and chemical parameters of groundwater qualities was investigated. Samples were collected at different periods of time of the day and analysed using the AOAC analytical method. The assessment of ground water parameters shows that electrical conductivity was 120, 450 and 450 us/cm; total dissolved solids were 110, 225, and 225 mg/L; temperature was 27.2, 29.4, and 29.5 0C; suspened solids were 0, 3.0 and 0 mg/L; turbidity was 0, 1.0 and 0 FTU; colour was 0, 0 and 0 Pt.Co; pH was 7.2, 6.9 and 7.1; iron content (mg/L) nitrogen (mg/L), 33.44, 29.48, and 33.0 respectively; total hardness was 62, 40 and 48 mg/L; hardness as CaCO3 was, 24.8, 16 and 19.2; hardness hardness as MgCO3 was 37.2, 24 and 28.8; total alkalinity was 12.4, 8.0 and 6.4 mg/L and phosphate as phosphorus was 0.06, 0.01 and 0.025 mg/L were analysed and World Health Organisation standards were used as standard for comparison of these parameters. Some of the tested parameters were within WHO recommendations while some were not.
