Regular agricultural land soil monitoring: According to the "Agricultural Land Regular Monitoring Principles," one agricultural land (in Dali District) is recommended to stop regular monitoring, while the other (in Dajia District) suggests maintaining a monitoring frequency of once every 8–10 years.
Concurrent crop sampling: A total of 97 soil samples were taken from agricultural land this year, with 89 samples funded by the project (8 samples were taken by the Environmental Protection Bureau). This also included one sample for XRF screening and one sample for the full analysis of 8 heavy metals.
This year, one plot exceeded the control standard for chromium, one plot exceeded the control standard for copper, nine plots exceeded the monitoring standard for chromium, and four plots exceeded the monitoring standard for nickel. Water quality sampling showed no abnormalities. Continuous water quality monitoring was conducted for 11 irrigation groups at 20 sites over a month. By monitoring abnormal frequencies and times, and combining agricultural land soil screening with nearby industrial distribution, 101 rapid-response capsules were deployed to successfully reduce the scope of high-pollution potential areas and industrial sources.
In Tanzi District, soil and groundwater verification for sections 25-1, 25-6, and 169 found that sections 25-1 and 25-6 failed the verification and will be announced as controlled sites under the Soil and Groundwater Pollution Remediation Act. For section 169, tetrachlorethylene and trichloroethylene still exceeded monitoring standards, and regular monitoring will continue as per the Act.
The verification of the Taiya-related gas station found that total dissolved solids, sulfate, and total organic carbon in the groundwater at monitoring wells MW7 and B00602 exceeded the second-class groundwater pollution monitoring standards, and regular monitoring will continue.
The Hongju Industrial Co. completed soil verification sampling on December 2, 2024, and the six heavy metals were all below the soil pollution monitoring standards, passing the verification. The emergency measures for this site will be lifted.
In terms of storage system declaration reviews, three quarterly reviews were completed. A total of 41 business units were assisted in confirming regulatory compliance for their storage systems, and follow-up guidance was provided. Among these, 12 business units still require improvement. A total of 48 storage system soil gas monitoring well tests were conducted, and 24 stations had deficiencies. As of mid-December, 10 stations are still being improved. For oil and gas detection, one station (Shanlong Wuci gas station) exceeded warning values for PID, FID, and LEL%.
The high-pollution potential industrial areas in the Datuliao Zhen District mainly fall around the Dawei Road area. In the Azauwu Second Zhen District, zinc and other complex pollutants are still entering the irrigation channels, and future preventive management and site inspections are recommended for the industries in these areas.
This year, two industrial briefing sessions were completed, meeting the performance evaluation requirements. Site inspections were conducted for Group A industries, and three businesses were selected for verification. Two businesses had soils exceeding control standards, while one business had soils with heavy metals below the monitoring standards. Industries with a REC score less than 8 were recommended to be moved to Group B, and businesses were requested to report their self-pollution prevention plans. Group B industries had site inspections from September 26 to October 15, where one business needed to apply for a downgrade to Group C, and another upgraded to Group A.
This year's public industrial land verification was completed for Xieyu Co., Ltd. in Tanzi, with the result showing that the eight heavy metals at all points were below the soil pollution monitoring standards. However, TPH at points S01 and S03 exceeded the soil pollution control standards, and relevant control measures are recommended. Additionally, Xieyu Co. should conduct supplementary surveys and improvement work on the soil and groundwater at the site.
This year, the installation of one standard well (B00608) and three simplified wells (B00609, B00610, B00611) was completed, along with 13 samples of groundwater volatile organic compounds and 4 samples for carbon isotope analysis. According to the investigation results, the pollution plume remains confined to the area of the Taiwan Agricultural Company and the Xiehe section (plot 200).
Hongshu Co. filed an appeal on December 20, 2024, against the Environmental Protection Bureau's decision. The appeal was rejected in the decision made on November 25, 2024.
A briefing session on the installation of solar photovoltaic systems was held on March 29, 2024, at the Wenxin Second City Hall with 78 businesses and 86 people attending.
