The total cost of this project is NT $ 10,700,000, and the overall working period ended on December 31th, 2018. However, until November 9th, 2018, all works have been finished and the results of works were described as follow.
As of November 9, there are 17 sites that have been announced of the control or remediation site in Hsinchu County, including: 4 remediation sites, 6 control sites, 7 sites may adopt necessary response measurement by Soil and Groundwater Pollution Remediation Act Article 7 Paragraph 5. During the year, a total of 5 verified work were completed and 3 sites were revoked.
In order to avoid progressing behind, this project carried out the regular inspection and supervision according to the frequency of checking. If necessary, the Environmental Protection Bureau and the Environmental Protection Administration also visit the sites to assist in the counseling. During this year, we completed 4 groundwater pollution sites scope verification work, which were Hsinchu Bus Co., Ltd in Hukou township, Hsinchu Science Park, Jing Yuh Metal Industrial Co., Ltd and Xinfeng Township Xinfeng Section 797 and other 3 land numbers. At present, the pollution area of each site is still under control. In addition, for the suspected new pollutants in Xinfeng Township Xinfeng Section 797 and other 3 land numbers, we carried out supplementary verification work, the results showed 2,4,6-trichlorophenol and pentachlorophenol exceeded groundwater pollution control standards. Beside, the control or regulatory site listing has been cancelled, Seiko gas station and Xinhukou Gas Station, groundwater quality monitoring results had not exceeded the groundwater pollution monitoring standards. Details of the work, please refer to section 2.3, chapter 3 and chapter 4.
In this year, this project continued to monitor the groundwater pollution of which the concentration exceeds the groundwater pollution monitoring standards, and high pollution potential areas, also to keep following the trends of pollutant concentration and surrounding business conditions. Results of monitoring were normal, such as in the groundwater of the river basin of Xiao-Li River and the downstream areas of the Philips Zhubei manufacturing plant (including Taihe industrial district). However, the chloroform concentration in the manufacturing plant of Taiwan Tanabe Seiyaku Co., Ltd exceeded the groundwater pollution monitoring standards. It is recommended to take necessary measures and investigate work in the year of 2019, to find the suspicious-sources of pollution as soon as possible, and announce it according to law. The NH3-N concentration of groundwater in RiTdisplay Corporation and En Hou Polymer chemical industries Co.,Ltd exceeded the groundwater pollution monitoring standards. The trichloroethylene (TCE) concentration of groundwater in Sanyang Motor Co., Ltd in Xinfeng township was exceeded the groundwater pollution monitoring standards as usual. The NH3-N concentration of groundwater in Sanyang Motor Co., Ltd in Hukou Township exceeded the groundwater pollution monitoring standards, and volatile organic compounds were detected around the underground storage tank. This project also monitored the emerging contaminants, the detected concentrations of related substances were low. Details of the work, please refer to chapter 5. Besides, because the monitoring well J00303 in Gaosuta company was buried by unknown wastes, so could not be found, the groundwater monitoring number was reduced.
This project completed the reviewing the underground storage tank declaration reports on the system, 11 gas stations were selected for conducting soil gas detection and reports check. This project also assisted to review the documents pursuant to Articles 8 and 9 of Soil and Groundwater Pollution Remediation Act, total in 33 new application businesses, from January 1stto November 9th, 2018. During this year, the average corrections was 1.62 times, and from payment to pass the review was about 59.31 days. The administrative efficiency has been significantly improved compared with 2017. At present, 29 applications have passed the review, and 4 applications were in correction progress. This project also assisted to check the industrial reporting data about the comprehensive, correction and abnormal check. This year, the investigation of soil and groundwater quality in Tang Eng Science Park and the investigation and verification of soil and groundwater pollution in Zhonglun Industrial district were carried out. Details of the work, please refer to chapter 6.
This project also completed twice-yearly inspections of monitoring wells, maintained the wells function, diminished useless wells, assisted in holding 13 campus education camps, 1 soil and groundwater pollution prevention public activity, and 1 international seminar. Details of the work, please refer to chapter 7.
