Assessment of Water Quality in Agaie-Lapai Dam: Implication for Water Supply in IBB University

Abstract

The environmental impact of developmental activities on land, water, air as caused by noise pollution and disruption of the delicate eco-system and the need to evolve an efficient approach to deal with such effects is now receiving focused attention. Therefore, the study was an environmental impact assessment of Agaie-Lapai Dam for irrigation and domestic water supply to IBB University, Lapai. This study carried out water quality assessment in of the area.Water quality, water samples were taken from the upper, middle and lower course of the River. The samples were analyzed at the National Cereal Research Badeggi Laboratory. The result of pH of the water samples were observed to range from 6.15-6.80, while Turbidity and Electrical Conductivity of the water samples were found to be in the range of 0.20-7.0 NTU and 50-1010 µs/cm, while results of the chemical tests for the water samples revealed that the total Alkalinity and total hardness range from 50-1150 mg/l and 3.9-18 mg/l and ranges of 0.7-2.2 mg/l. Also 2.88-5.36 mg/l were recorded for BOD and COD and the Concentrations of Nitrate and Ammonia- Nitrogen of the water samples were observed to range from 3.47-60.58 mg/l and 0.08-2.90 mg/l respectively, Therefore, the result for water from Agaie/Lapai dam can be used for domestic purposes and it needs further treatment as a measure for it to be consumable.
