This project is the "108 Annual Survey and Verification Work on Soil and Groundwater Pollution in Nantou County". The work mainly includes the collection of historical data of soil and groundwater monitoring plans, the management and tracking of soil and groundwater pollution, and high pollution in the jurisdiction. Supervision and management of potential industries, as well as data collection based on soil and groundwater pollution sources, to grasp the groundwater quality status of the county's industrial zone, and to monitor and verify the management site. This year, a total of 197 groundwater monitoring wells were inspected, and 6 wells were maintained and 3 wells were repaired; another 13 wells were evaluated for well conditions, and 7 re-completions and 5 were completed based on the assessment results. Oral foreign body exclusion. In addition, waste well evaluation is also performed for the actual monitoring needs and well conditions of each monitoring well in the area, and waste well operations for 5 standard wells are actually performed. This year, the team completed the sampling and detection of groundwater in the 107 new year wells (M00212, M00213), the potential area of ??the NK07 site in Nangang Industrial Zone (M00104, M00118, M00165) and Yuyou gas station (M00108). 10 inspection and analysis operations were completed. According to the test results, in the 107 new wells, heavy metal chromium was detected in the dry season during the dry season and the detection exceeded the control standard; during the high water season, it was reduced to the control standard. Groundwater heavy metal chromium detected in the potential area of ??NK07 site continued to exceed monitoring standards. Yuyou gas station detected that the originally announced pollution project benzene was reduced below the control standard; the total petroleum hydrocarbon project exceeded the control standard. The online declaration review of the underground storage tank system was completed in accordance with the prescribed schedule, and 95 site inspections, 5 missing inspections in 107 years, and 5 missing inspections in 108 years were completed. As for the improvement inspection and supervision of pollution sites, there are still 8 pipeline sites in the county as of November 30, 108. 3 site verification operations have been completed this year; 95 of them are in Nangang Section, Linzi Section, Nantou City, Nantou County. No. and Zhuzhou Industrial Site have completed decommissioning. The verification result of No. 270 of Nangang Section, Linzi Section, Nantou City, Nantou County is in compliance with the improvement standards and pending deregistration. The emergency response operation is based on the situation that the monitoring well M00213 exceeds the control standard during the dry season; the sampling and detection of civilian wells and the analysis of soil heavy metal in the well location in the downstream area around M00213 are handled. In addition, a 107-year investigation was conducted by the Environmental Protection Agency to check the soil arsenic of the Hongqiang International Copper Plant No. 2 over the control standard. According to the verification results, the plant's soil pollution was only at the EPA's investigation. This year, ten campus promotion activities and two seed teacher training camps, as well as the operation instructions meeting of the underground storage tank network declaration system, were completed. Through these activities, participants and practitioners have more in-depth and correct understanding of regulations and related cases. Understanding, and make the general public have more understanding of the prevention and control of soil and water pollution, and then work together to protect the quality of soil and water in Nantou County.
