"The 107th Nantou County Soil and Groundwater Pollution Investigation and Verification Work Plan" is mainly for the important prevention and control of soil and groundwater pollution within the jurisdiction of Nantou County. This year's work objectives include the application review of the underground storage tank system in the county and on-site inspection and lack of counseling. Interview and verification of high-pollution potential factories; inspection and maintenance of groundwater monitoring wells in the jurisdiction and periodic monitoring of groundwater quality to maintain monitoring well functions to ensure the current status of groundwater quality and pollution concentration changes; Conduct regular inspections and implementation of relevant control measures and supervise the implementation of pollution improvement, and complete the verification work to complete the verification of the site pollution improvement has confirmed the improvement effect; assist the Environmental Protection Agency to strengthen the promotion of soil and groundwater related to the announcement business, underground storage system operators and professional institutions The decree's propaganda instructions and education and training; and the implementation of environmental education to the national small and medium-sized this year, through the implementation of campus promotion activities to promote the importance of soil and groundwater environmental protection, has achieved the goal of sustainable use of soil and groundwater resources in Nantou County.
In this regard, the Environmental Protection Bureau of the Nantou County Government (hereinafter referred to as the Environmental Protection Bureau) entrusted Asia-Pacific Environmental Technology Co., Ltd. (hereinafter referred to as Asia-Pacific Company) to implement the “107 Nantou County Soil and Water Resources” in 107 years. The groundwater pollution investigation and verification work plan (hereinafter referred to as the plan), the implementation period of the plan is from the start date of the contract (January 1, 107) to December 20, 2007, the number of planned work and The progress of the work is in line with the contract. Some of the funds have not been found to have high pollution potential due to on-site inspection and leak detection at this year's gas station. Soil and groundwater verification has not been carried out, and the implementation of unexecuted work items has been paid back according to the contract. In order to handle the settlement of the project.
The main work of this project can be divided into six major projects, including underground storage tank system related operations and 8, 9 verification work, high pollution potential soil and groundwater investigation, groundwater quality monitoring and monitoring well maintenance operations, soil and groundwater pollution. Key work such as site verification operations, professional meetings, education and training, and administrative coordination matters, as well as public sentiment or emergency response work, the following summary of the implementation results of this year's work projects.
First, the underground storage tank system related operations
According to the contents of the contract work, the project has been on-site inspection and verification for the missing gas station in the previous year before the mid-term report is submitted. The site inspection and check-up work of the gas station was completed 14 days before May 31, 107. The results of the review have all been improved, and the annual improvement rate of missing is 100%.
This year's on-site inspection and counseling operations were completed on-site check-up and lack of improvement counseling before the final report was submitted. On-site check operations were conducted for 94 stations in operation, 21 of which were inconsistent with the underground storage tank management method. The project includes soil gas monitoring wells with unclear 13 stations, oil tanker at the bottom of the tanker to prevent oil spills from 5 stops, no monthly soil gas monitoring or inspection projects, 2 stations and the total number of oil guns and declarations. There are 2 stops for the data.
This year, we found that there are missing gas stations. The lack of review and counseling for each station has completed 21 stations in October 2007, and only one has not completed the improvement.
Gas station leak test function test and oil and gas test operation, this year completed a total of 14 stations of leak test function test and oil and gas test, including the number of executions this year based on past site check and past year report data screening may have potential pollution potential A total of 6 stations were executed, and the 106-year implementation of the pollution potential was determined to be B1 level (National Weisheng). It needs to be tracked and checked four times. Last year, it has been completed twice, so this year's continuation tracking is performed twice, and the EPA's online audit notification is abnormal. The situation is tracked 1 stop (New Nantou Interchange); the EPA informs that the pollution potential is B2 (Zhongxing Gas Station) needs to be tracked four times a quarter, a total of 4 times, and the leak test function test in September 107 The oil and gas test found the abnormal Puli unified Seiko 2 station; the pollution potential was determined to be B1 level (checked every two months). The first tracking of this year was completed on November 16, 2007, and the relevant work was completed according to the contract.
Second, high pollution potential soil and groundwater investigation
According to the results of groundwater monitoring in Nangang Industrial Zone over the years, the groundwater in Nangang Industrial Zone mainly has heavy metal chromium and chlorine-containing organic pollutants. In addition, the types of pollution sites in the industrial area are currently listed; mainly the heavy metal pollution category sites.
The high-pollution potential soil and groundwater survey of this project depends on the pollution potential in the industrial zone, and is aimed at the industry's most high-potential soil and groundwater investigation site for the most common metal products manufacturing industry and metal surface treatment industry in Nangang Industrial Zone. The screening list of interviews is based on the factory within 500 meters of the monitoring well with the detected pollutants, the factory that has been in violation of the industrial area wastewater detection in the past, the use of pollutants of concern, and the shaving has been carried out in the past three years. Factory for on-site interviews.
This year, the first phase of the project selected 15 times for on-site interviews; the second phase selected 4 homes for on-site interviews, and completed 19 field interviews this year. After on-site interviews, it was found that three of them had high pollution potential, five had moderate pollution potential, and 11 had low pollution potential or no pollution potential.
Among them, 3 furniture high-pollution potential factories selected Shangyu Xinye Co., Ltd. to enter the site to carry out soil pollution verification operations. Shangyuxin Co., Ltd. discovered that it has a high pollution potential and improved the lack of improvement in the year of 105. On-site inspection and inspection still found that there were damage to the pavement in the process area and the flow of waste water in the wastewater treatment area, so the soil pollution verification operation was arranged. According to the results of the verification work, there were 2 points of soil heavy metal nickel exceeding the soil pollution control standard.
3. Groundwater quality monitoring and monitoring well maintenance operations
(1) Monitoring wells are regularly tested
The monitoring well is regularly monitored. The project completed 17 sampling tests for the dry and dry season. The monitoring area is the downstream warning network of Nangang Industrial Zone and the NK07 heavy metal chromium pollution site (M00165).
Monitoring well test results General project Only Nangang Industrial Zone Sewage Treatment Plant (M00068) and Early Warning Network #5 (M00114) detected ammonia nitrogen exceeding the monitoring standard during the abundance and dry season. The heavy metal project detected more than the monitoring standard in the NK07 heavy metal chromium pollution site (M00165) in the abundance and dry season. The well was detected from the Republic of China from 1997 to 101. The concentration of heavy metal chromium has been reduced since 103 years. Exceeding monitoring standards did not meet regulatory standards. In addition, the NK07 heavy metal chromium pollution site downstream monitoring well warning network #10 (M00118), although not exceeding the monitoring standard, continued to detect the pollution concentration, showing NK07 heavy metal chromium pollution site, heavy metal chromium pollution situation has a downstream diffusion situation. The volatile organic compounds project was not detected in this year's test results.
(ii) High-risk approach to well testing
In response to several groundwater pollution areas in Nangang Industrial Zone, including the Anshun site, the downstream of the NK07 site, the lower reaches of the Yuyou gas station, and the Yuye Industrial, there are high-pollution risk sites around the site for the investigation of the underground wells. This year is in the dry season. Carry out the sampling and testing of 8 underground wells, the test items are tested according to the pollution characteristics of different sites, the Anshun site detects volatile organic compounds; the downstream of NK07 site detects heavy metals; the Yuyou gas station detects total petroleum hydrocarbons; The industry detected volatile organic compounds. The test results only showed that the concentration of heavy metal chromium in the wells in the downstream area of NK07 was higher than that in drinking water sources. The other three sites were not detected.
(3) Monitoring well inspection and maintenance
Monitoring well inspection and maintenance operations, as of the end of the reporting period, the delivery date of November, 107, before the completion of the first quarter of 107 (49), the second quarter (49), the third quarter (48) and the fourth quarter ( 49) Among them, the monitoring well M00094 completed 48 wells in the third quarter of 107 degrees in July. The fourth quarter inspection operation included the newly built wells in the inspection and performed 48 times. The plan was not included in the inspection. The well was inspected and maintained by the county's self-financing research project; and 13 well monitoring wells and micro-water test operations were completed, and the well records were selected through inspection records. The wells were poorly monitored and 6 wells were observed. Maintenance and repair of 3 wells facilities, inspection records are uploaded to the SGM system according to regulations.
(iv) Waste well operations
This year, two monitoring wells were completed, which were monitoring well M00094 (Successful Sanlu and Ziqiangyi Road intersection). The well was found to have been damaged by the inspection in the previous year. This year, after discussion with the Environmental Protection Agency, the well was considered Disposal of waste wells without monitoring. Monitoring well M00138 (Mingtan gas station) was originally set up to investigate the station when the soil was found to be contaminated by total petroleum hydrocarbons; whether the groundwater is contaminated, the station has been depleted after pollution improvement, and the test record has been declared for nearly 2 years. If there is no abnormality, the monitoring well waste operation should be handled.
(5) Well-setting operations
This year, two monitoring wells were set up, which were monitoring well M00212 (Dagang Section 106, 107). This well was used to investigate whether the groundwater was polluted for this year's emergency response site. The monitoring well M00213 (downstream area of NK07) is based on the survey results of this year's high pollution potential wells; it is found that the heavy metal chromium pollution is still detected in the downstream areas; the monitoring wells are newly established to understand the concentration and range of heavy metal chromium pollution in the downstream area.
4. Soil and groundwater pollution site verification operations
For the inventory site, this plan will be inspected at least once a month this year. If the site is improved during the improvement period, the inspection frequency will be inspected every two weeks, and important improvements will be made at the site, such as dispatching personnel to the site. The supervisor confirmed that the improvement work was in line with the proposed improvement plan. The project carried out site inspections according to the frequency specified in the contract and uploaded the inspection records and photos to the SGM system.
This year's pollution improvement completed the verification work to complete a total of five site verification operations, including the Nangang section of No. 270, Linzi Section of Nantou City (hereinafter referred to as Li Ying Business), Nantou City, Niuyun Rising Section 32-6, No. 37 Land, Yingsheng Industrial Co., Ltd. (hereinafter referred to as Yingyuxing) and Nangang Section of Linzi Section of Nantou City (hereinafter referred to as Jintao Chemical).
Both the Li Ying business and the Jintao Chemical verification results still have soils in some areas exceeding the soil pollution control standards; both sites have requested improvements to the unit to re-improve pollution and re-submit the pollution control plan.
The other three sites were verified through the site including Yingyingxing Co., Ltd. The verification results were in line with the improvement target, which was released on August 23, 2007. The verification results of No. 32-6 and No. 37 of Nantou City were consistent with the improvement. The target was released on October 15, 107.

The relevant work and quantity were completed according to the contract quantity.
Sixth, the people's feelings or emergency response work
(I) Anshun site monitoring well sampling test
Since this year's monitoring well sampling and testing operation area has no planned monitoring and sampling operations around the Anshun site, after discussions with the Environmental Protection Agency, it is agreed to implement the emergency response fund for the four monitoring wells around the Anshun site (M00041, M00098, M00169, M00178) Sampling and testing operation, the detection result only found that the monitoring wells M00041 and M00178 in the Anshun site have exceeded the monitoring standard, and the downstream monitoring wells (M00098, M00169) were not detected, indicating the pollution of Anshun site. The situation is non-proliferation and continues to be below regulatory standards.
(2) Emergency strain sampling test of No. 106 and 107 in Dagang section
The emergency strain sampling system was carried out by Meishang Magnesium Technology Co., Ltd. in the new plant project. The retaining wall project was carried out on the southwest side of the site. The excavation operation revealed that the organic solvent smell was scattered, and then on July 26 The company notified the Environmental Protection Bureau and the Industrial Zone Management Service Center to conduct on-site survey operations. After receiving the notification, the project immediately cooperated with the emergency strain sampling plan. The emergency strain sampling operation was carried out on August 2, 2007. The test results showed The soil in the site was exposed to the soil pollution control standard by volatile organic compounds xylene, and a new groundwater monitoring well was set up. The groundwater test results were not detected.
