The overall work focus of this project can be roughly classified into (1) groundwater pollution monitoring, investigation and well maintenance and management operations; (2) Agricultural and Food Department synchronous sampling of agricultural land, regular monitoring of agricultural land and photoelectric guidance operations; (3) contaminated sites Site inspection, management and GSR audit operations; (4) Contaminated site improvement verification operations; (5) Industrial land pollution prevention and management operations; (6) Underground storage tank system guidance management and audit control operations; (7) Above-ground storage tank system Guiding and auditing work; (8) Public complaints and emergency response investigation work; (9) Handling the review of project information for listing management announcements in Articles 8 and 9 of the Soil Pollution Law; (10) Relevant laws and regulations publicity and administrative cooperation work.1.Groundwater pollution monitoring, investigation and well management: This year, the number of outward appearance inspections, 12 out-of-the-way maintenance operations were carried out and 1 wells for non-monitoring purposes were used to abolish, 6 wells were repaired. During the high and low water period at 2023, The test result of the 2 wells at 661 the Dung-guang area show that O00194 data exceeded the control standard for Trichloroethylene (0.0818 mg/L), and the Trichloroethylene is an upward trend compare with last year, then evaluate whether to initiate a response.This plan assisted in completing the change of contract content on September 15, 2012, and injected EOS biological nutrient salts on September 28 for the two batches of high potential O00194 and O00427, and completed the post-dosing VOCs on November 2 Regular monitoring and bacterial phase analysis operations are conducted to assess whether the groundwater quality at the site has been adapted to an anaerobic dechlorination environment and whether the groundwater pollution concentration has been significantly reduced..Frog-5000 measured trichloroethylene, dichloroethylene and vinyl chloride and other 10 monitoring wells (O00066、O00300、O00193、O00338、O00067、O00069、O00197、O00200、O00361、O00341). None of the screening tests exceeded the control standards.In the regular monitoring part of Xiangshan Industrial Zone, four areas with restricted use of contaminated groundwater (land numbers 832-2, 809, 920, and 731 of the Renai Section) will implement the flood season in the four areas on September 7-8, 2023 by joint agreement. Groundwater sampling and the first regular monitoring results after delisting were all below the second-category groundwater pollution control and monitoring standards.2.This plan "Crop Pollution Monitoring Control and Investigation". In 2023, completed the first phase of 15-point sampling in the first half of the year (5 points mixed with 1 point) and the second phase of the second half of the year with 10-point sampling (5 points mixed with 1 point). Two of the cadmium crops in farmland exceeded the limit standard. , further analysis of the soil samples showed that it was lower than the agricultural soil monitoring standard; the test results of other crops were all qualified.This plan cooperates with the EPA to handle the prevention and management of agricultural land pollution potential zoning, and completes the on-site survey of 41 irrigation group agricultural lands within its jurisdiction (including 7 pollution prevention and control areas, 10 pollution early warning areas and 14 excellent protection areas). According to the current situation, the irrigation groups (central group and Lengshuikeng group) that no longer have farmland were excluded. In the first half of the year, 39 farmland sampling tasks were completed, and the heavy metal concentrations analyzed by laboratory XRF did not exceed the control standard value; from July 29 to On October 11, a total of continuous water quality monitoring, 5 sets of water quality sampling preliminary inspections, 9 sets of water quality sampling re-tests and 50 sets of time-lapse capsules were carried out on the Tingfu Zhen Eight-wheel branch line and the Tingfu Zhen Niupu River branch line to strengthen upstream water quality traceability and pollution. prevention work. In addition, from October 19th to 23rd, XRF was used to screen heavy metals in the sediments of three Shenzhen roads that had exceeded the upper limit in the past (Jiujiapuzhen, Longenzhen, and Keya Nanzhen). The test results showed that the sediments It is not obviously polluted, mainly between the upper and lower limits of sediment, and has no obvious pollution potential.This year, we continued to assist in taking stock of the city’s past intentions to install photovoltaic facilities on farmland. We have applied for the installation of photovoltaic facilities on farmland in 7 land numbers, with a total application area of 1.22 hectares in 4 cases. Meter power generation was completed on June 30. , with a total power generation capacity of 1.55 megawatts (MW).3. The management of pollution improvement sites:According to the characteristics of each site and the improvement of the established management system, A+-level sites (inspection at least once every 2 weeks, and increased frequency depends on the situation), A-level sites (inspection at least once every 2 weeks), and B-level sites ( Inspect at least once a month) and C-level sites (inspect at least once every 2 months). During the inspections carring PID equipment (once a season) to measure the SVE exhaust gas and the surrounding air VOCs. Every month, and complete the soil improvement and follow the car for off-site operations in accordance with the prescribed route and timetable.4.This plan has selected Beimin Co., Ltd., which has the highest GSR score, as the current GSR survey site this year. It completed the written review of the "Site Checklist for Best Management Practices for Contaminated Sites" on May 16, 2023. On July 21, the on-site inspection of the "Best Management Practices for Contaminated Sites Site Inspection" was completed. 5.Three contaminated sites were completed in 2023 - Hsinchu Oil Supply Service Center (No. 13, Dongming Section), No. 981-1, 981-2, 981-3, 981-5, Dongguang Section, Hsinchu City, and Xingxiong Industrial Co., Ltd.’s verification work, in which the Hsinchu Oil Supply Service Center completed the
