Abstract

Heterotrophic studies of bacteria and fungi organisms were carried out on water samples from Ureje and Ero dams. Problem statement: Water from Ureje and Ero dams is used for the municipal water supply for drinking and for agricultural purposes. The level of contamination of bacteria and fungi organisms has not been ascertained. Approach: Heterotrophic studies of bacteria and fungi organisms were therefore carried out on water samples from the Ureje and Ero dams. Results: The results of the water analyses show that Ureje dam has 140 x 105 bacteria count while the Ero dam has 2.8 x 105 bacteria count as their minimum counts respectively. Their maximum counts are 150 x 105 and 3.0 x 105 and averagely 150 x105 and 2.6 x105 respectively. The water is contaminated as a result of an anthropogenic effect of man and animal wastes. The Ureje and Ero dams have fungi count of 3.0 x 102 and 1.0 x 102 as minimum counts and maximum counts of 4.0 x 102 and 2.0 x 102 with average counts of 3.5 x 102 and 1.5 x102 respectively. The fungi counts indicate that the water is contaminated through agricultural activities around the dams. The probable number of coliform [PNC] and E coli organisms [EC] per 100mls of water samples from Ureje dam is 75 coliform per 100ml of water and 15 E-coli per 100ml of water while Ero dam has 23 coliform per 100ml of water and 9 E.coli per 100mls of water. The World Health Organization [WHO 2002] recommends a standard of 0/100ml of both E coli and coliform for drinking water. Conclusion: The water from the two dams is contaminated based on the recommended standards. The possible isolates are bacteria [E coli sp, klebsiella sp., trichoderma sp.and pseudomonas sp.] and fungi [aspergillus sp.,].These indicate that the water in the dams is equally contaminated.
