Description:

Water samples from Nworie River in Imo State were assessed for bacteriological and physiochemical qualities using standard laid down procedure. Some of the results obtained indicated that upstream samples had higher microbial loads than the other sample which were 3.5X105 cfu/ml, 6.2X107 cfu/ml, and 3.0X103 cfu/ml respectively on MacConkay agar, nutrient agar and Sabauraud Dextrose Agar. Micro-organisms identified included Escherichia coli, Staphylococcus aureus, Streptococcus faecalis, Aspergillus species, Mucor sp., and Talaromyces sp. The
physiochemical properties of the river gave the value of 5.6, 17.3ms/cm and 4.5mg/l for pH, conductivity and salinity respectively. These qualities could justify the level of human activity on the river and the same time shows that the river has a large contamination index which is unsuitable for portable uses. The aim of this research is to identify and isolate micro-organisms associated with Nworie Rivers as to assess its level of contamination.
