Environmental Protection Bureau, Chiayi City (referred to EPB, CYC) has carried out the soil and groundwater pollution investigation and audit project since 2004. EPB, CYC still follows the concept of “prevention is better than cure” to implement this project.
The achievements of final report are listed below：
1. Monitoring groundwater quality periodically：according to the analytical result of groundwater samples of two monitoring wells, As, Pb are lower than Groundwater Pollution Monitoring Standards. These monitoring wells should keep investigating.
2. Maintenance of 21 monitoring wells: it includes exterior inspection, repairs and environmental cleanup for each well. The function of monitoring to each well is still workable.
3. Inspection and cleanup of two monitoring wells: purging air into the tube of the well removes sediments. Then, recording the interior of the well ensures the result of cleanup.
4. Management of underground storage tanks system (USTS) enterprise: the system includes reviewing the data via online application and on-site audit. One station audit has been accomplished. The major fault is the difference between document and actual situation of site. Such fault would inform to owner, then ask to correct the fault in specified duration to follow up for improvement.
5. Announcement of business land use verification process: during the examining process, nothing susceptible has been found before the mid-term report.
6. Regulation explaining session: the session helped the participants understand more about the Soil and Groundwater Pollution Remediation Soil and was held at CPC Chiayi branch on March 29, 2019.
7. Educational series: through interactive storytelling and videos, children can learn about the importance of conserving soil and groundwater resources.
8. Printed children books: "Small Animals, Big Detectives" and "Little Water Drops?" were printed (total of 1,400 copies, 700 for each).
9.Regular inspection of pollution-controlled sites: four pollution-controlled sites and one pollution-remediated site are examined monthly. Abnormal condition and/or illegal behavior has not been found during the monthly checks. The data were input to the Soil and Groundwater Management Information System (SGM system) for reference.
10.Emergency Plan and Execution: one event was completed, which was monitoring quality of farmland periodically. According to the analytical results, the concentration of As or Cr in three farmland blocks are lower than the Soil Pollution Control Standards. Thus, these blocks should be kept monitoring.
11.Assisted EPB, CYC reviewing the soil pollution assessment survey and inspection data of the soil and groundwater pollution remediation laws of 8th and 9th. By the end, three cases needed review; no abnormalities were found in the review results, the documents were uploaded to the SGM system.
12.The Soil and Groundwater Pollution Remediation laws of 8th and 9th Announcement Business Check: the preliminary screening of the management of the jurisdiction has been completed. The investigation is planned to be carried out from July to September, and the list of businesses and the re-screening factors will be released to determine the potential for high pollution.
13.Self-use and oil storage tank inventory: In response to the EPA's amendment to the "Water Pollution Prevention Act, Article 33, Item 1 of the business designated by the Central Competent Authority", the inventory of the storage facilities with a total volume of more than 200 liters and compliance with relevant regulations shall be investigated. Initially selected 7 companies that meet the requirements for self-use and storage tanks.
The EPB, CYC still continued mainly focuses on monitoring the quality of groundwater and soil.
