Abstract

The physico-chemical properties of water samples from five sampling stations at Mmubete River were monitored for a period of two months with the aim of determining its suitability for human consumption. The establishment of the five study stations was based on flow pattern and the activities at each sampling station. The stations are: upstream and point of minimal pollution. 200m downstream and spot used for sand dredging. 400m downstream and point for car wash. 600m downstream and point of direct discharge of abattoir wastes and 800m downstream and point of manual dredging and close to where slaughtered animals are washed. The study investigated the presence of Coliforms and other physico-chemical characteristics defining the suitability of the water for drinking according to World Health Organization standard for drinking water. Results were compared with World Health Organization limit for safe drinking water. The variation in some physico-chemical parameters appears to be closely related to the activities at the sampling stations. The results showed higher levels of turbidity (97.5 NTU); Biological oxygen demand was 102 mg/l, Total Coliform was 846 CFU/100ml. These higher levels were attributed to human activities taking place in the river. The level of dissolved oxygen at the five stations was very low with an average of 0.9 mg/l and this can be a potential risk to fish and other aquatic organisms. The values of some physico-chemical parameters were above the acceptable limit which suggests possible negative consequences of water pollution and poses risk to human health and therefore not suitable for human consumption without treatment.
