Absrtact	The project was aimed to remediate 174 numbers of restricted farmlands with a total area of around 22.1699 hectares. The amount of soil discharged from these farmlands was around 9,207 tons. Among them, the investigations of 157 numbers of the restricted farmland sites were finished based on the previous project, and still, 17 numbers of restricted farmland cases have been ongoing in the current project. In our team works, we found that some of the restricted sites were completed remediation, and lifted the site restriction. After the four times contract modification, the total numbers of the restricted site that needed to be remediated were 169 (the area of restricted farmlands were 22.1699 hectares, the soils discharged were 9,232.5 tons) and 1 site for investigation. The heavy metal species that cause farmland contamination was mainly Copper (Cu), followed by Zinc (Zn) and Cadmium (Cd). There were 75 numbers of restricted farmlands (around 12.204 hectares) that were remediated by soil dilution method, 94 numbers of restricted farmlands were remediated by soil excavation method with clean soil backfilled, and one site (0.0139 hectares) did not need to be remediated as the site was not for agriculture use. According to the contract, the project began in August 1st, 2018 and ended on June 20, 2020, and the achievements included (1) conforming the degree of heavy metal pollution in 17 numbers of farmlands, (2) finishing 169 numbers (22.1699 hectares) of farmlands ground clearance and remediation, (3) discharging 8,772.10 tons of polluted soil, (4) importing 8,808.93 tons of clean soils, (5) completing the verification of 169 numbers (22.1699 hectares) and finishing the fertilization of remediated farmlands and obtaining the consent form of completion from landholders, (6) summiting the lifted restricted farmland application for 170 (22.1838 hectares) numbers of restricted farmlands sites.
