  • 摘要:The water stream in Desa Kejapanan, Pasuruan, East Java, Indonesia used as a source of water for households and field irrigation is indicated to experience heavy metal contamination. The purpose of this study is to determine the type and concentration of metals in the water stream that is contaminated with metal washing waste. The concentration of heavy metals in water and sediments was tested using the Atomic Absorption Spectrophotometer (AAS) method. In this case, the physical and chemical components of the water measured were color, temperature, pH and DO. Meanwhile, the data of heavy metal concentration was tested using ANOVA and was analyzed descriptively. The data were analyzed using SPSS version 16.0 software. The test results point out that the concentration of mercury (Hg) is ranged from 0.028±0.002 mg/L to 0.036±0.005 mg/L while lead (Pb) is in between 0.492±0.009 mg/L and 0.665±0.007 mg/L, cadmium (Cd) in between 0.142±0.011 mg/L and 0.161±0.004 mg/ L, zinc (Zn) in between 0.737±0.006 mg/L and 0.763±0.004 mg/L), and copper (Cu) in between 0.318±0.004 mg/L and 0.369±0.002 mg/L. It is known that Zn has the highest concentration of metals compared to other metals while the highest concentration of all types of metals (Hg, Pb, Cd, Zn, and Cu) occurs in the sample S2. The water stream is indicated to have been contaminated by heavy metals (Hg, Pb, Cd, Zn, Cu) because the concentrations of these metals have exceeded the maximum qualification both in water and sediments.
