Diversity and Levels of Bacteriological Contamination in Orashi River, Mbiama Community, River State, Nigeria

This study evaluated the level and diversity bacteria contamination in River Orashi in Mbiama community, Rivers state of Nigeria. Triplicate samples were obtained from three stations viz: upstream, downstream and midstream. Standard bacteriological methods were employed for the analysis. Total heterotrophic bacteria, total coliform and fecal coliform ranged from 3.00 to 7.00 x 106 cfu/ml, 12.00 to 15.67 MPN/100 ml and 7.00 to 14.00 MPN/100 ml respectively. Analysis of variance showed that there were no significance difference (P>0.05) among the various location apart from total heterotrophic bacteria that was significantly different (P
