1. Soil Reguler Analysis
This year, a total of 19 sites, where the contamination in soil exceeds the monitoring standard, were investigated. The result shows that the concentration of heavy metals Arsenic(As) were found to exceed control standards in 1 site, where some of area that the lands irrigated using groundwater full of As. Other 11 sites were found to exceed monitoring standards.
2. Simultaneous sampling of soil and crops
The project has cooperated with Agriculture department to finished simultaneous sampling of soil and crops. Because the crops aren’t abnormal, so no soil analysis required.
3. Agricultural land pollution prevention management
This project is set to conduct regular environmental surveys and assessments in the month of June in the year 112, with soil sampling on agricultural land and water for irrigation taking place between July and October. The results indicate that the soil and irrigation water quality are in accordance with monitoring standards, among them, 1 sites were found to exceed monitoring standards.
4. Source investigation of sediment in the irrigation channel
“Long-En” channel conducting investigations into sediment and irrigation water quality. The outcomes reveal that the channel water quality complies with regulatory standards, while the accumulation effect has led to elevated concentrations of arsenic and zinc in the sediment, exceeding the prescribed limits. The contamination is not of anthropogenic origin. It is recommended that subsequent measures include the execution of sediment dredging operations.
5. Industrial land pollution prevention management
From July to October, on-site inspections have already been carried out for 10 entities in Group A, 6 entities in Group B, and 19 entities in Group C, pertaining to their environmental inspection(Phase I surveyed). The project choce 2 Group A factories those moer potential to soil and groundwater contamination verification. One of them, the results showed that chromium(Cr) and nickel(Ni) in soil concentration have exceeded the control standards, subsequently, regulatory measures will be enforced in accordance with legal requirements.
6. Industrial pipeline investigation
Between the months of September and November, an industrial pipeline investigation will be carried out. Geophysical surveys will be employed to confirm the pipeline locations, followed by soil, groundwater, and soil gas investigations.soil The results show that soil were complied with monitoring standards,whatever, soil gas PID/FID testing, one location has exceeded the alert threshold. It is advisable to take maintenance and preventive measures in accordance with water pollution regulations.
7. Earthwork waste materials management
The random sampling and testing of earthwork waste materials materials reveal that the concentrations of heavy metals remain below the monitoring standards.
8. Groundwater Analysis
Sampling work of all 21 wells has been done in May, 2023, and the results in 3 monitoring wells, the underground water exhibits arsenic concentrations surpassing the monitoring standards, while in 9 monitoring wells, the general parameters exceed the specified monitoring criteria.
9. Wells Maintenance and Checking
The project had completed, as contracted, a total of 2 times of quarterly work of the checks and maintenance of regional and on-site monitoring wells, according to the results, 5 of them went through the external maintenance after the assessment, 2 facilities of wells has been repaired; 2 of it was abolish；the establishment of a single well. In addition, for the condition assessment on 10 monitoring wells; according to the results, 5 of them went through the internal maintenance after the assessment, and 5 of them went through the well development again followed by camera shooting inside the well to assure of tidiness.
10. Restrained Sites Management and Verification
The PVEEC has carried out the monthly inspection over restrained sites for the progress of improvement and the latest condition in hand and evaluate the predicted effects for the site where the remediation plan has been accomplished. Currnently, there are totally 2 sites that has completed post-improvement verification.
“台灣中油股份有限公司蘇澳供油服務中心” and “蘇澳油料分庫(代號CC-13-30營區-1” verification results still exceed the control standards, necessitating ongoing control measures.
11. Management of businesses with pollution concerns
The PVEEC has completed 11 soil and groundwater legal-related written review, 13 soil and groundwater legal-related on-site inspection.
In September, the verification of soil contamination for businesses with pollution concerns will be conducted, the results showed that TPH in soil concentration have exceeded the control standards, subsequently, regulatory measures will be enforced in accordance with legal requirements.
12. Designated pollutant storage system management
The PVEEC has been associate with EPB to complete the storage system reports of Q3 in 2022 (from Sep to Dec) and Q1 in 2023 (from Jan to Apr) and Q2 in 2023 (from May to Aug), with 100% of inspection. We also had monitored gas stations of 9 Subterranean storage tank system. Additionally, there will be the execution of compliance verification, guidance, and reevaluation efforts for 15 storage systems that align with the newly defined industry categories. In cases of pollution concerns, it is advised to implement maintenance and preventive measures in accordance with water pollution regulations.
13. Management of soil and groundwater quality in industrial zones
The PVEEC aims to assist in verifying and consolidating the reporting and testing data for soil and groundwater in industrial zones. With the exception of the Hsinchu Science Park Yilan Park, where elevated levels of ammonia nitrogen, iron, and arsenic are attributed to environmental factors, the industrial zone reporting data conforms to regulatory standards.
14. Emergency Response
The total number of tasks that our company has assisted in handling with the emergency contingency funds amounts to eight.
15. Event Handling and Routine Business
This year, there have been completed 1 conferences for interpreting the new law “Regulations for Installation and Management of Facilities for Preventing Pollution of Groundwater Bodies and Monitoring Equipment in Underground Storage Tank System” (total audience number: 46); 1 conferences for the Article 8th and 9th Regulations on Soil and Groundwater Pollution Remediation Law (total audience number: 39); 1 conferences for Guidance seminar on business categorization and classification management, as well as self-regulated pollution prevention management plans (total audience number: 50); 10 educational sessions and 1 training courses (total audience number: 407). The PVEEC has also filming the video based on the work of this project.
