Project Executive Summary Project Name: 108 Annual Soil and Groundwater Pollution Investigation and Verification Work Plan-Hsinchu City Organizer: Fulian Engineering Consulting Co., Ltd. Project signing period: January 01, 108 to December 20, 108 Implementation of the quantified target statistical interval: January 01, 108 to November 30, 108 Executive summary notes:     The plan starts from the signing date and ends on November 30, 108. The cumulative work progress is 100%, and the work results are explained as follows: I. On-site groundwater well monitoring Execute groundwater sampling and analysis twice a year (dry season and high season) of groundwater in the area with high potential for groundwater pollution in the area under jurisdiction, and conduct regular monitoring of groundwater quality during the dry season from March to April for monitoring wells in the groundwater restricted use zone of the Dongguang section In July of the second half of the year, regular monitoring of groundwater during the high water period was carried out. The testing items were volatile organic compounds (VOCs) listed in the groundwater pollution control standards in order to grasp the situation of groundwater quality. There were 12 times of monitoring during the dry season and 12 times of monitoring during the high season, for a total of 24 times. Inspection of monitoring wells The plan has performed 251 monitoring well appearance inspection operations at a frequency of one each in the second half of the year, including 15 sub-regional monitoring wells and 114 sub-site monitoring wells in the first half of the year, and a total of 122 monitoring wells in the second half of the year Well, and fill in the monitoring and maintenance record form for the appearance of the monitoring well. The relevant electronic files have been uploaded to the "Soil and Groundwater Management Information System-Soil and Groundwater Pollution Remediation Network" of the Environmental Protection Agency. Third, maintenance of external wells and internal functions of monitoring wells The plan has performed external well maintenance operations such as 13 secondary well maintenance updates and 8 secondary well equipment repairs; internal functional maintenance operations have performed 25 secondary groundwater well condition assessments and 4 foreign body removals based on actual conditions And 13 wells were completed again to ensure that the well conditions of the monitoring wells were good and the sources of groundwater hydrology and pollution information obtained from the monitoring were credible. 4. Inspection and Pollution Investigation of Underground Storage Tank System Operators The plan has carried out on-site inspections for 59 gas stations and 1 electronic component manufacturing industry in Hsinchu City. Six of them have been selected for leak test tube function tests and oil and gas detection PID / FID screening tests. The results are all below 500 ppmv. Soil gas detection. Fifth, the site inspection work There are 13 polluting sites in Hsinchu City in 108 years. The plan will regularly perform supervision and inspections every month, with a total of 138 inspections, including 22 inspections for A + sites, 21 inspections for A sites, and B inspections for B sites. 41 site inspections and 54 C-level site inspections. Sixth, the improvement of the pollution site and the verification work are completed The plan has completed the improvement and verification of 3 polluted sites, namely, Taiwan PetroChina Co., Ltd.-Siwei Gas Station, Hsinchu Science Park Zone 19 and surrounding areas, and 661 Dongguang Section of Hsinchu City; PetroChina Siwei Gas Station It has been announced that the control site and the soil pollution control zone will be lifted. The well No. 19 in the park and No. 661 in Dongguang Section are expected to convene the fourth regular meeting of soil push to review whether it will be released. Seven, waste well operations The plan has completed 3 simple wells (2 PetroChina Peking University gas stations in Taiwan, and 2 Juya Units Co., Ltd.) and 5 standard wells (National Jiaotong University Pok Oi Campus-shallow well, deep well, Fuyou Palace-shallow well, deep well, Love to buy green land next to) waste well operations. Propaganda (Communication) Work This plan is for all underground storage tank operators in Hsinchu City to conduct one session of "Underground Storage Tank System Management Measures and On-site Inspection Operation Publicity Briefing Session" to promote the operators to strengthen independent management and effectively communicate policy ideas and laws and regulations; complete one session each Educational training for business personnel and personnel training at the management site; completion of one session of the eighth and nineteen regulations of the management business; briefing sessions for seed lecturers and completion of the certificate and book donation ceremony; one session "National Symposium on Soil and Groundwater Pollution Remediation Techniques" promotes the exchange of practical experience in soil and groundwater pollution investigation and verification. The source detects organic chlorine-contaminated sites and reuses brownfields after remediation at the site; one session is held Cross-county and city business exchange and observation activities, through the experience sharing of other counties and cities on the management of site management, to strengthen soil and groundwater pollution control experience and supervision management. Nine, public sentiment and emergency response work and verification work (1) 4D gas station verification A verification planning review meeting was held, and the reviewing committee suggested that an additional groundwater sampling point should be added to the site to confirm that the pollutants had not spread. (2) Qing O Section 390, 391, 1106-1     As the content of inorganic arsenic detected by the three plots of rice in Qing O section exceeded the limit of heavy metals set by the hygienic standard for contaminated substances and toxins in food, agricultural land pollution verification was carried out in accordance with the preceding operating principle, and emergency response operations were performed on the agricultural soil and the soil. The previous soil sampling test results of irrigation groundwater sampling showed that the arsenic content was lower than the monitoring standards of soil pollutants; the detection results of groundwater for irrigation wells were lower than the second-class groundwater pollution control standards. Follow-up invite agricultural units to guide farmers to adopt appropriate farming techniques or farmland conversion and continue to strengthen monitoring in accordance with the "SOP for Agricultural Crop Heavy Metal Pollution Monitoring and Control Procedures (SOP)". The preliminary reason may be that the arsenic of rice exceeded the control standard due to improper farming practices.
