Plan of Soil and Groundwater Pollution Investigation and Verification Work in Penghu County, 2023

英文摘要 As of December 20, 2023, 100% of the work items have been completed, including: monitoring well inspection and maintenance, groundwater monitoring and sampling during dry and high water periods, gas station inspections and leak detection pipe surveys, storage system inspection and guidance, pollution improvement completion site verification, agricultural land soil pollution prevention sampling and analysis , project preventive management effectiveness tracking, regulatory briefings, best management practices (BMPs) inspection operations, solar photovoltaic facility promotion briefings, announced project reviews and technician inspections, emergency response operations, etc., are summarized below. 1. Monitoring well inspection and maintenance and repair operations The inspection carried out re-completion of 2 monitoring wells that showed abnormal well condition assessment, and completed the appearance maintenance of 2 monitoring wells, the repair of facilities in 1 monitoring well, the removal of foreign matter in 1 monitoring well and the operation of 3 abandoned wells. 2. Groundwater monitoring The dry season monitoring was completed from March 24 to 29, 2012. None of the 6 monitoring wells exceeded the monitoring standards for heavy metals and volatile organic compounds. Only the second type of monitoring standards were exceeded for general items; wet water The first-term monitoring was completed from August 21 to 22, 2012, and the analysis results were similar to those in the dry season. None of the six monitoring wells exceeded the monitoring standards for heavy metals and volatile organic compounds. 3. Gas station inspection and leak detection pipe investigation The monthly audit showed no abnormality; during the leak detection pipe investigation operation, 18 stations were completed from March 24 to 29, 2012. Among them, the leak detection pipe No. 4 of Pengda Gas Station had a PID exceeding 1000 ppmV, so the inspection was carried out. GC/FID quantitative analysis of soil gap gases in the leak detection tube showed that MTBE reached 944 ppm, methane reached 151 ppm, ethane reached 146 ppm, and propane reached 781 ppm. According to the conclusions of the initial report review meeting, the Pengda gas station test was conducted again in July. During the leakage pipe investigation, the PID of the leakage measuring pipe No. 4 was 41.4 ppmV and the FID was 7.5 ppmV. The measured values were within a reasonable range. 4. Storage tank system audit guidance It was completed the compliance confirmation of 1 underground storage tank system and the improvement review of 5 above-ground storage tank systems. This county is a major marine tourism county. Hotels and B&Bs in the county have the need to use storage systems. Therefore, relevant inspections have been carried out. An inventory of 1,195 registered hotel and B&Bs has been completed. Among them, 37 have ceased operations. There are 23 hotels and 2 B&Bs have storage tank system. 5. Contamination Improvement Completed Site Verification Wai'an Fishing Boat Gas Station site submitted an improvement report in July 2011, and conducted agency verification on March 23 and 25, 2012. The soil sampling point was 6 points and the groundwater sampling point was 2 points. The test results showed that the soil and groundwater were in compliance with the requirements. Pollution control standards, this site was delisted on May 5, 2012. 6. Prevention of agricultural soil pollution This county has 6 towns including Magong City, Huxi Township, Baisha Township, Xiyu Township, Wangan Township, and Qimei Township. It needs to conduct 6 sets of soil and water quality sampling tests. Three environmental survey assessments before the sampling tests will be completed in April. Agricultural land suitable for sampling was found and soil sampling was completed in July. The heavy metal test results were all lower than the control standards for edible crop farmland. The irrigation water sources of the 6 sampling agricultural lands were all private wells. On August 21 Irrigation water sampling was completed on the 23rd. Heavy metals in the irrigation water of various agricultural lands were lower than the irrigation water quality benchmark value or not detected (N.D.). Because the concentration of heavy metals chromium and nickel in the soil of Baisha Township's agricultural land is higher than that of other towns, the irrigation water was re-tested at a private well next to the agricultural land in Baisha Township. The test results showed that the heavy metals were lower than the irrigation water quality benchmark value or not detected (N.D.). 7. Tracking of prevention management effectiveness of enterprises In cooperation with the promotion of enterprise independent monitoring and preventive management systems, a briefing session on independent preventive management operations of Group B enterprises was held on May 23 to explain the relevant processes and system operation methods of independent preventive management operations to Group B institutions; Group B enterprises were held on August 8 On October 10, he went to Taipower Corporation's Jianshan Power Plant and on October 20, he went to Taipower Corporation's Penghu District Sales Office to conduct on-site inspections and provide revision suggestions on the contents of the independent pollution prevention and management plan; Group C business unit went to Taipower on September 27 The company's Magong seawater desalination plant and Taiwan Water Company's water purification plant were successfully inspected on October 17 to confirm whether there were any process changes or abnormalities. 8. Activities of Soil and groundwater pollution A briefing session on the key points of storage system regulations and system declaration regulations will be held on June 19. The invitation targets are storage system operators in the county. The seminar will be held on storage system management methods and declaration operations, so that each storage system operator will have a deeper understanding. ; On the same day, a promotional briefing on the promotion of solar photovoltaic installations on contaminated land and related sites will be held. The invitees are management units of existing polluted sites to promote solar photovoltaic installations in line with renewable energy policies. 9. Audit of Best Management Practices During the site improvement progress report review meeting, review whether the improvement unit has implemented best management measures. In order to confirm whether the best management measures are implemented, on-site inspection operations are required; on June 26, we went to Huxi Fuel Supply Center and Magong Bus For sites such as gas stations, review committee members are asked to provide on-site inspection suggestions for reference by the improvement unit for subsequent promotion. 10. Review of Announced enterprises and Audit of signature by Professional Environmental Engineers In accordance with Articles 8 and 9 of the Soil and Groundwater Pollution Remediation Law, Beichen Gas Station submitted soil pollution assessment investigation and testing data on October 11. After reviewing the data and notifying the enterprise to supplement the data, the Environmental Protection Bureau approved the relevant data on October 26. material. Technician inspection operations are carried out in accordance with the relevant regulations on management examinations of the Ministry of Environment. Last year, there was only one case in this county where soil pollution assessment investigation and testing data were submitted by Penghu Gas Station of Uni-President Precision Industry Co., Ltd., so the technician in this case was listed as the technician of this year. For the audit work targets, committee members were invited to conduct a written review in July and an on-site inspection was conducted in October. The inspection results were classified as level 2 deficiencies. 11. Emergency response Ministry of Environment notified the county's reservoirs that the concentration of heavy metals in the sediments is higher than the upper limit. Considering that the county's reservoirs are sources of drinking water for residents, if the heavy metal concentration is higher than the upper limit, it is external pollution and may affect the safety of residents' drinking water. Therefore Emergency response operations were carried out to investigate the sediment near the reservoir inlet and outlet to clarify the source of heavy metals in the sediment. The nickel measurement value of the reservoir sediment exceeded the upper limit of the sediment quality index. Although it was affected by the parent material, However, the high nickel value in the sediment is not entirely due to the nickel content of the original parent material. The phenomenon that the nickel value in the Xingren Reservoir sediment exceeds the upper limit of the sediment quality index should be caused by the characteristics of the parent material. During the sampling and analysis operations for the prevention of agricultural soil pollution, it was found that the concentration of heavy metals in the agricultural soil in Baisha Township and Magong City was higher than the soil pollution monitoring benchmark value for edible crops. Kaoliao agricultural land crops are provided for residents to eat, in order to clarify the agricultural land Sources of heavy metals in the soil, so emergency response operations were carried out to conduct soil sampling and analysis around farmland. The phenomenon that the measured values of heavy metals in farmland in Baisha Township and Magong City exceeded the benchmark value for soil pollution monitoring in edible crop farmland should be caused by the characteristics of the parent material and irrigation. The quality of the groundwater used is not polluted by heavy metals, and the irrigation water is not the source of chromium and nickel in agricultural soil.
