The confirmation survey of contamination was conducted for 24 pollution control sites of farm land in Tainan. Employing a two-stage approach, the survey identified 15 sites with low pollution potential and 9 with higher pollution potential. Within the low-pollution potential sites, one site underwent a detailed assessment of contamination extent and status. After communication with interested party, a pollution control plan was implemented in accordance with guidelines. The remaining 14 sites were included in "The Project of Remediation Measures on Restricted Farmlands in Tainan City" for individual improvements. The project's supervision and verification confirmed compliance with improvement requirements, leading to the public announcement of the cancellation of control or regulatory listing for a 1.08-hectare area. For the higher pollution potential sites, one site was managed by the interested party, while the remaining 8 sites underwent pollution management operations, including the installation of fences, non-woven fabric coverings, and phytoremediation experiments following risk assessment. The managed area covered 0.74 hectares. To fulfill land management responsibilities and prevent recontamination, ongoing guidance is provided to interested parties. Regular inspections and supervision, integrated into routine soil and groundwater pollution management projects, will be crucial for future monitoring. In cases lacking funds for immediate improvement, health risks will be controlled through pollution management. Additionally, adopting phytoremediation will not only address pollution but also yield multiple benefits such as enhancing environmental quality, reclaiming abandoned land, and contributing to climate change mitigation.
