ABSTRACT
Coliform bacteria analysis of river Amba in lafia, Nasarawa State was carried out for twelve months. The period of studys covered both rainy and dry season. Water samples were collected monthly from four different locations (Gandu, Wadatan-Waje, Kofan-Kaura and Ungwan- Galadima) along the river course. Coliform bacteria analysis was carried out using Multiple Tube Method. The mean total coliform bacteria values recorded for Wadatan-Waje and Ungwan-Galadima during the rainy season were higher than that of dry season. During rainy season, the mean coliform bacteria load for Wadatan-Waje location was 16.3a±0.00 CFU/100ml while for dry season; it had mean coliform bacteria of 14.95e±0.05 CFU/100ml. Ungwan-Galadiman had 8.17±0.27a CFU/100ml mean coliform bacteria load during rainy season and a 6.00a±0.27CFU/100ml during the dry season respectively. Conclusion was made that the mean coliform values varied along the sampling stations due to levels of discharges of untreated sewage.
Key words: Coliform, bacteria, analysis, River Amba and Nasarawa.
