ebruary of 106. They are the south side of the Douliu Industrial Park, the north side of the Park, and the sixth naphtha cracker industrial Park. The process includes monitoring wells in the factory, public road monitoring wells in the industrial area, and public area. Investigate soil contamination beyond the standard or monitoring groundwater contamination. The pollution is as described below. (1) The south area of the Douliu Industrial Park. The survey results in the southern area of Douliu Industrial Park showed that there were two monitoring wells that found groundwater contamination. The P00488 monitoring well in the Fuqiao company and P00588 monitoring well of public road and DL03 monitoring well. The former detected more groundwater fluoride salt than the Standards. The second category of groundwater pollution control standards, the latter for tetrachloroethylene exceed groundwater pollution control standards. (2) The North area of the Douliu Industrial Park. The survey results in the northern plot of the Douliu Industrial Park show that the heavy metals in the Urban soil of the three factories exceeded the pollution control standards, and that the five factories of outside the factory had detected heavy metals exceeding the pollution control standards in the urban soil. In addition, There are nine area of heavy metals in the urban soil at the Fuxing Road and the Dougong 2nd Road exceed the pollution control standards. (3) The sixth naphtha cracker industrial Park The results of the investigation in t the sixth naphtha cracker industrial Park show that there is a site of heavy metal in the soil exceeding the pollution control standards, and the original remediation site of the aromatics third plant P00296 monitoring wells detected new pollutants TPH exceeds the groundwater pollution control standards, and P00295 monitoring wells detected heavy metals arsenic exceeded pollution control standards.
