The target of main project is to verification of Supervised and technical support, etc. In supervised and verify side, this project supervises the implementation and verification improvement work in the role of a third party notarization. Let this plan achieve the goal of maintaining people's health and promoting land reuse. And in technical support side, establish internal engineering management mechanism and control progress. Management work includes document control, progress control, holding of working seminar, communication and coordination and coordination work and review of consolidated reports, etc. The project has completed 20-person-month on-site supervision work, and filled in the supervision log to record the daily work situation. Including soil pollution investigation, falsework, soil screening test, soil pollution remediation work, soil Sampling, off-site remediation. In addition, the work report and work discussion meeting are regularly organized every month, a total of 20 times. Soil screening test complete a total of about 200,838 m3(300,892.97 ton), and complete the supervision of 108,360 m2 of pollution remediation area. Perform 10 points per hectare for verification work, and complete a total of 123 verification sampling points. This work has completed 8 heavy metal XRF screening samples in 983 groups and total analysis samples in 141 groups, and completed 12 groups of dioxin analysis. The analysis results are all in compliance with the contract requirements. In addition, 1,156.98 tons of contaminated soil off-site supervision and vehicle follow-up work were completed based on the soil off-site disposal plan for inspection. According to the off-site disposal plan of contaminated soil, that supervised the departure of 1,156.98 metric tons of contaminated soil and tracked the whereabouts of off-site vehicles.
