The project is "107 Hsinchu City Soil and Groundwater Pollution Survey and Verification Work Plan". The main contents of the work include the data of the soil and groundwater monitoring plan, the management and monitoring of soil and groundwater pollution, and the high pollution in the area. The supervision and management of the potential industry, as well as the collection of data on soil and groundwater pollution sources, the groundwater quality of the industrial area of the city, and the supervision and verification of the pipeline site.
A total of 250 groundwater monitoring wells were inspected this year, and 13 wells were updated and 6 wells were repaired. Another 26 monitoring wells (regional 4, field-of-the-field 22) were evaluated. According to the results of the evaluation, 13 re-completions were completed (regional 2, field-set 11) and 5 foreign bodies were excluded. In addition, the waste well assessment was carried out for the actual monitoring needs and well conditions of each monitoring well in the area, and the actual operation of three standard wells was carried out.
This year, the team conducted a total of 44 groundwater monitoring wells in the high-pollution area (Hsinchu Science Park, the surrounding area of Well No. 19 in the park, Xiangshan Industrial Zone, and Zhongyou Hsinchu Oil Depot) to perform groundwater sampling analysis during the dry and wet seasons, including Hsinchu Science Park. The main concern is that the pollutants are chlorine-containing organic compounds. The sampling results in the dry season show that shallow wells and deep wells beside the waterfront of the Minhang Park, Zhucun 2nd Road, Gaofeng Guoxiao, Industrial Dongsan Road School Park, and the industrial Dongsan Road water tower. The 6 monitoring wells have detected trace amounts of chlorine-containing organic compounds below the monitoring standard. The results of the flood season test show that Yuzhu Village Second Road, Minxiang Park, Industrial Dongshi Road (next to the expressway), industrial The six monitoring wells in the shallow green and industrial wells behind the water tower of the East Third Road School Park and the industrial Dongsan Road water tower, although the detection of chlorine-containing organic compounds, are also lower than the monitoring standards.
In the dry season of Xiangshan Industrial Zone, the main concern is that the pollutants are also chlorine-containing organic compounds. The test results show that only Xiangming Technology has detected traces of cis-1,2-dichloroethylene with a concentration lower than the monitoring standard. The results showed that the detection concentration of trichloroethylene in the mouth of No. 568 of Niupu East Road exceeded the control standard, and the results were consolidated with the information of the Xiangshan project monitoring and investigation, and the nearby 5 factories were selected to be included in the high-pollution potential area this year. .
In the downstream area of the Hsinchu Oil Supply Service Center, the results of the monitoring of dry and wet seasons showed that the benzene of the side door of the oil depot exceeded the control standard during the dry season, and the methyl tertiary butyl ether exceeded the control standard during the wet season, and the supervision was strengthened. To prevent the spread of pollutants in the site.
In addition, the groundwater sampling survey of the wells in Xiangshan Industrial Zone was conducted. This year, five wells using groundwater were sampled. The results of the wells of Hairuigong Pills showed that the concentration of trichloroethylene exceeded the regulatory standards because the site was food. Industry, and other monitoring wells in the vicinity can continuously track the changes in the concentration of trichloroethylene in groundwater, so they are advised to conduct sealing operations. In the case of Yulonghe Rubber, the monitoring standard of trichloroethylene was also detected. The test results will be consolidated into the Xiangshan project plan, and subsequent visits and sampling and verification will be arranged.
Based on the sampling and testing results of the monitoring project and the Xiangshan project monitoring well and the well, the 13 high-pollution potential factories were selected together. Eight factories were visited by the Xiangshan project, and five factories were visited. The results of the visits of the five factories show that the site of the Kailuan enterprise and the predecessor of Juya Textile is most likely to be a source of chlorinated organic compounds. Therefore, the results of this interview analysis are summarized. The Xiangshan project plan will be planned for subsequent sampling and verification operations.
In the improvement and inspection of pollution sites, 18 sites were listed in this year. Among them, the two sites of Kandong Bridge Gas Station and Haishan Section 492 were dismantled in the middle of this year, and another Air Force Base and 2 sites. Xiangshan farmland will be decommissioned by the end of this year; the remaining seven pollution control sites include Xiangshan Gas Station, Guangming Gas Station, Siwei Gas Station, Ersan City Park Ersan Road, Science Industrial Park No. 19 monitoring well surrounding area, Hsinchu Oil The oil supply service center and the Xiangmin factory of Beimin Company; the 6 restrictions on groundwater use include the No. 981 of the Dongguang section, the 661-0 of the Dongguang section, and the Renai section of the Xiangshan project. Only the Hsinchu Oil Supply Service Center has not been approved due to the change plan, resulting in delays in progress, and the rest of the improvement progress is in line with the planning period.
This year, 20 gas stations were screened for written check, leak detection function and oil and gas detection, and 3 stations of 5 points GC analysis were carried out. According to the analysis results, the sampling and verification were carried out, and finally the soil of the national Hsinchu gas station was confirmed. After being contaminated by TPH, the industry has responded to the statement and will take emergency measures in accordance with Article 7 of the Soil Pollution Law.
During the year, a number of promotional activities and conferences were held, including business personnel education and training, national seminars, regulations and briefing sessions, cross-county city observation activities, management site training, campus roving and cooperation. The “Three-State Guardian Festival” activity, through these activities, allows relevant professionals and practitioners to have a deeper and correct understanding of laws and related cases, and to make the general public have more understanding of the prevention and control of soil water pollution, and work together. And guard the quality of earth and water in Hsinchu City.
