IMPACT OF WASTEWATER MICROORGANISMS ON THE HEALTH OF RESIDENTS IN SALEM UNIVERSITY COMMUNITY

ABSTRACT

A total of 24 wastewater samples were collected from three different sampling stations of a private University at different times of morning and evening based on the peak of activity of the stations (Stations GHM, GHE, BHM, BHE, CAFM, and CAFE). The samples were examined for Temperature, pH, Biological Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids, Total Dissolved Solids, Total bacterial and fungal counts. This was done to isolate and identify different microorganism associated with the wastewaters and their possible health effect. The mean temperature and pH values of samples ranged from 24.50C to 26.50C and 6.12 to 7.99 respectively. The Biological Oxygen Demand of the samples ranged between 2.0 – 25.0mg/L with CAFÉ having the lowest value and GHE the highest value while the Chemical Oxygen Demand of samples ranged between 0.01 -0.45mg/L with GHE having the lowest and GHM the highest value respectively. The population of bacteria were determined, isolated and identified as Escherichia coli, Streptococcus spp., Enterobacter spp., Pseudomonas spp., Staphylococcus spp., Flavobacterium sp., Pseudomonas sp., Proteus spp., Klebsiella spp., Bacillus spp., Micrococcus spp., Alkaligens while 4 fungal genera were identified as: Aspergillus spp, Penicillum spp, Mucor spp, Rhizopus stolinifer were also identified. Faecal water indicators and pathogenic organisms were identified to be associated with wastewater and this can have negative health impact on humans within the surroundings.
