Preface: Biological water quality assessment of water being supplied to Male hostels at Obafemi Awolowo University, Ile Ife was done by collecting samples from flowing tap and storage tanks in each hostel over a period of six weeks. The tap and storage water supplied to the male hostels was found to consist of a total of 46 genera of plankton of which 15 were zooplankton and 31 were phytoplankton. The genera belong to 7 phytoplankton phyla (Bacillarophyta, Chlorophyta,Euglenophyta, Ochrophyta,Dinoflagellata, Cyanobacteria and Charophyta)and 5 zooplankton phyla (Cercozoa, Rotifera, Amoebozoa, Arthropoda and Ciliophora).Class Zynematophyceae (Division Charophyta)was the most abundant phytoplankton, represented by six species (Closterium ehrenbergii, Strogonium, Genicularia, Zygnemopsis, Docidium and Zygnema). Of these species, Genicularia was the most abundant. Amongst the Zooplankton,Mononogonta was the most abundant as represented by nine species namely Argonotholca foliacea, Trichocerca bicristata, Trichocerca chatonni, Trichocerca elongata, Trichocerca porcellus, Trichocerca similis, Brachionus calyciflorus, Brachionus falcatus and Hexarthra mira. The most abundant zooplankton species was Cyclops bicuspidatus of the class Maxillopoda. The highest total abundance was recorded at the sixth week of sampling. It was also observed that the number of organisms recorded from the tap water (43245 Org/L) were more abundant compared those from the storage tanks (30735 Org/L), however in terms of diversity more species were recorded from the storage tank.
Some organic pollution indicator species (Phacus pleuronectes and Nitzschia) were also recorded. Hence, further work should be done on the biological assessment of water being supplied to the hostels to advice on more efficient and effective treatment system which should be implored to purify and avert further pollution of the water.
