Environmental Management Administration

In recent years, the administration has actively promoted active management and prevention efforts among enterprises, conducting rolling discussions and adjustments based on actual implementation results. Beyond areas such as farmland, factories, storage systems, industrial zones, and sediment regions, regular patrols and surveys are carried out. Pollution risk potential is assessed, and the scope and targets of investigations are continuously expanded. Potential pollution sources are inventoried, and management measures are promptly developed. Additionally, through various reporting channels and the joint supervision of environmental protection bureaus and the public, pollution prevention effectiveness is enhanced, aiming for immediate control to reduce time and resources required for subsequent pollution management.

Since 1982, farmland soil surveys have been conducted to progressively understand the condition of farmland soil that may be contaminated by heavy metals, promoting verification and remediation efforts. To prevent recurrence of pollution, starting in 2023, nationwide farmland pollution prevention work has been implemented. Monitoring is carried out based on pollution potential classification, including random testing of soil and irrigation water quality, activation of pollution tracing and control mechanisms in cases of abnormal farmland conditions, and continued monitoring and pollution source management to ensure agricultural production safety, sustainable land use, and the protection of food safety and environmental quality.

For high-pollution-potential sources such as storage systems, factories, and industrial zones, a complete soil and groundwater pollution prevention system has been established.

• Storage systems: According to the “Regulations on the Installation and Management of Facilities and Monitoring Equipment for the Prevention of Groundwater Pollution from Storage Systems,” amended in December 2020, businesses are required to install protective and monitoring facilities to prevent leakage and contamination from storage tanks.
• Factories: Since 2023, factories have been managed in groups based on pollution potential, with guidance provided to promote autonomous prevention measures.
• Industrial zones: Since 2010, monitoring and tiered signal management of industrial zones have been strengthened. Through information disclosure and tier-based control, pollution risks are reduced.

These measures enable early detection and timely control of pollution, reinforce corporate responsibility, and ensure the sustainable use of soil and groundwater resources.

To effectively prevent groundwater pollution, about 460 regional monitoring wells have been established since 1993. Regular sampling and analysis are conducted to understand background groundwater quality. Monitoring items include heavy metals, volatile organic compounds, and general water quality indicators. Monitoring frequency is adjusted according to changes in water quality.

Through enhanced monitoring of pollutants exceeding standards, precise data collection, and active management measures, groundwater pollution risks are effectively reduced, ensuring that groundwater quality remains within safe limits and continues to provide clean water sources.

The administration is committed to strengthening supervision and prevention through multiple measures, regularly inspecting and controlling pollution sources, reducing pollution at its origin, and effectively protecting farmland, industrial zones, and groundwater resources from contamination.
