An assessment of total coliform levels of some portions of River Gongola in Adamawa State, Nigeria

Oliver N. Maitera and Ismaila Y. Sudi

Bacteriological assessment of River Gongola in Adamawa State was carried out in the following locations along Rivers Gongola; Bare (RGBW), Dasso (RGDW ), Behind dam east (RGDBEW ), Dam west bank1 (RGDW1W ), Dam west bank2 (RGDW2W), Bobere (RGDBW ), Behind dam west (RGDBWW ), Dam east bank 1(RGDE1W), Dam east bank2 (RGDE2W) Kiri (RGDKW). The sampling was done in the months of February, March, April, 2007 representing dry season and in the months of August, September and October 2007 representing wet season. The poor plate method was used for determination of total coliform. It revealed high values (59.7 to 308.3 CFU/100ml of water) in wet season compared to those of dry season (12.1 to 100.7 CFU/100ml of water). This may be as result of runoff from animal faeces due to rains and these values were higher than the WHO/NAFDAC recommended standards.
