Agricultural activities cannot be separated from the use of agrochemical, both chemical fertilizer and pesticides. As the largest water user sector, agricultural activities are a source of water pollution. This study was carried out in Brantas' upper stream along paddy fields, Karangploso Subdistrict, Malang District. The river water samples were collected along the paddy field. The samples were collected when ahead of the harvest season. During the harvest season, pesticides were not sprayed but the concentration of pesticides in the river is quite high. Because no studies have previously measured Organochlorine Pesticide levels in the river along paddy fields, this study is an important contribution to the knowledge of organochlorine contaminants present in surface water in Karang Ploso Subdistrict. The river water has a high concentration of organochlorine pesticides of 400.000 ppt, Total Dissolved Solids (TDS) of 226,8 mg/L, Biological Oxygen Demand (BOD) of 10,2 mg/L, Dissolved Oxygen (DO) of 3,8 mg/L, Chemical Oxygen Demand (COD) of 36,4 mg/L, total phosphate (PO4-) of 0,2 mg/L, nitrate (NO3-N) of 0,7 mg/L, Total Suspended Solids (TSS) of 53 mg/L, and potential of Hydrogen (pH) in lab and field of 8 and 7,08, respectively.
