| Summary: | The aim of this study is to determine the relationship between physico-chemical parameters with existence and diversity of macrobenthos at four selected stations at Penchala River. WQI was determined by analysing water samples through water sampling routine for 12 months starting November 2013 until October 2014. In situ measurements involved were temperature, pH, dissolved oxygen (DO), total dissolved solid (TDS), and conductivity. Laboratory analysis was undertaken for total suspended solid (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Ammoniacal Nitrogen (NH3-N). Measurements for physical parameters were done for water level, river width, and river water velocity. The WQI value Penchala River were in the range of 58.1 – 71.0. Station 2, 3, 4 received pollutant from difference sources such as residential, commercial and industrial area which discharged high concentration of nutrients and organic pollutant. The natural physical characteristics at Station 1 encourage the existence and support high diversity of macrobenthos. The deterioration of water quality, velocity and water level thus affected the existence of macrobenthos at Station 2, 3 and 4. The Pearson’s correlation of coefficients shows high correlation between WQI and Margalef richness index (r= -0.735, P=0.007), Simpsons diversity index (r= -0.618, P=0.032), Shannon-Weiner diversity index (r= -0.642, P=0.024) and Pielou evenness index (r= -0.589, P=0.044) indicate that biological monitoring at Penchala River by using macrobenthos is suitable as an alternative way to determine the river health. |
