Assessment The Levels Of Heavy Metals And Water Quality In Cikuda River, Indonesia

This study was conducted to assess the impact of activities in campus University of Padjadjaran (UNPAD) on the water quality as a result of the entery of pollution materials from laboratories, food courts, agriculture and domestic waste in campus UNPAD to Cikuda River. The accumulation of heavy metals in fresh waters has direct consequence to man and ecosystem. This study was aimed to determine the concentration of Pb, Zn and Mn, and water quality in Cikuda River. Samples were collected from nine sites. The total metal contents in water were determined using Atomic Absorption Spectrophotometer (Shimadzn AA-6300) Pb 0.01mg/L, Zn 0.62±0.48mg/L and Mn 0.14±0.13mg/L. Our survey showed that Pb lower than Standards Quality Regulation of the Republic of Indonesia No.82, 2001, about water quality management and control of pollution. Zn and Mn higher than Quality Standards. For the other water quality parameters the results showed that significant pollutional increase at the effluent impacted site. pH 6.93±0.67, BOD 2.68±1.91mg/L, Nitrate 0.60 ±0.96mg/L, Ammonia 0.80 ±0.16mg/L, PO40.29±0.10mg/L, DO 4.28 ±1.45mg/L Temperature 26.65 ±1.22C° and Transparency 38.33 ±17.31cm. A close monitoring of water pollution and metals pollution is strongly recommended especially in water.
