    Abstract: Tracking of copper in the soils contaminated by a nearby printed circuit board (PCB) waste recycling plant and the wire-burnt residue has been
    studied by X-ray absorption near edge structure (XANES) spectroscopy. The contaminated soils have a very high total and leaching concentrations
    of copper which are in excess of limit (15 mg/L). By XANES, we found that Cu(OH)2 (44%), CuCl2 (34%), and CuSO4 (16%) were the main copper
    compounds in the soil contaminated by the copper slag that was discharged from the PCB recycling plant. The additional contaminated site caused
    by the illegally wire-burnt residue also has high total and leaching copper concentrations. The main copper compounds in the contaminated soil
    were CuSO4 (41%), CuCl2 (39%), and Cu2O (19%). In the downstream soil (nearby a river (2 m)), the main copper compounds such as Cu(OH)2
    (46%), Cu(NO3)2 (35%), and Cu2O (9%) were found. The speciation of copper in the contaminated soils can be very helpful in the development
    of effective remediation methods.
