【 摘 要 】

The present study was conducted to assess the level of Organophosphate Pesticide contamination in shallow aquifer of Surabaya and Sidoarjo coastal areas. Selected organophosphate pesticides compounds (chlorpyrifos) of contaminant have been determined in the in shallow aquifer of Surabaya and Sidoarjo. The samples were then analyzed by using gas chromatography and followed by using the method of Standard Method Examination. The result showed that the average concentration of chlorpyrifos organophosphate pesticides in Surabaya and Sidoarjo were 0.0004 and 0.0021 ppm respectively. The highest concentration of Chlorpyrifos organophosphate pesticide in Shallow Coastal Groundwater Aquifer showed on Siodarjo (0.0021 ppm). The Chlorpyrifos organophosphate compound detected in these areas may be discharged from agriculture activity in the upland.
