The best water quality on average is found in the river during the month of January, and the lowest quality during August. This could be attributed to the level of faecal coliforms, and BOD levels indicating bacteria in the water during August from fig.2. Dissolved oxygen levels are also very low in August which is to be expected since the levels of bacteria in the water were also very high, and require oxygen to respire. Phosphate and nitrate levels tend not to fluctuate significantly during the time scale.
