The indices of the cool season show mostly moderate water quality, except that poor water quality is
observed at sampling locations A1, A7 and A8. The hot season brings about some improvement in water
quality, namely the class changes to "Moderate" at sampling points A1 and A7. A more significant
improvement is observed in the rainy season, when the water quality class is "Good" in general, except at
sampling locations A1 and A8. This is due to the diluting effect of the runoff [14].
