As of December 20, 111, the project has completed 100% of the work items, including: monitoring well inspection and maintenance, groundwater dry period monitoring and sampling, gas station leak detection pipe investigation and new storage tank regulatory compliance confirmation, as described below. The following are descriptions of the work items completed up to December 20. 1、Monitoring well inspections and maintenance and repair operations Four monitoring wells with abnormal well conditions were inspected, four wells were re-completed and four wells were cleaned of foreign objects, three wells were abandoned, one monitoring well was repaired and two were simply maintained. 2、Groundwater Monitoring Operations During the dry season, the results of the six monitoring wells were below the monitoring standards for heavy metals and volatile organic compounds. In addition to the two monitoring wells at the Unity Precision Petrol Station, the other four wells also have corrosion potential. The six monitoring wells monitored during the period of abundant water were all below the monitoring standard for heavy metals and volatile organic substances, with the general items exceeding the Type II monitoring standard, and continuous monitoring is recommended. 3、Petrol station audits and investigations The monthly audit showed no abnormalities; in the 18 stations leak detection and tube investigation, the FID values of one gas station at Ma Kung and one gas station at Beichen each exceeded 250 ppmV. Soil sampling and groundwater monitoring wells have been set up at the Chimei Fishing Boat Petrol Station and the test results are not abnormal. 4、Compliance with regulations for the new business of underground storage tank system The inspection of 18 factories on the list has been carried out, of which 5 are non-regulated and 10 have no deficiencies. 3 simple power plants on the third outlying islands have been improved as of November 20, 2011 due to difficulties in material transportation. 5、Activities In response to the new amendment to the Water Pollution Control Act, the Director of the Environmental Protection Administration and his executive team were invited to a briefing session on April 6, 111 to explain the regulations of storage facilities. On 18 November 111, we invited the storage system reporting vendor to the site to explain the reporting and system operation. Completed storytelling presentations at 10 campuses. The film was also shot. 6、Site inspection and emergency response This year, we completed the investigation of the Chimei Fishing Boat Fuel Station and found no contamination. There was no abnormality in the groundwater test results for one case reported by the public. In addition, groundwater testing and oil pattern analysis were conducted at the second fishing port in Magong, and it was confirmed that the leak was caused by the Chinese oil company.
