107 Soil and Groundwater Pollution Survey and Verification Work Plan - Miaoli County (hereinafter referred to as the plan) mainly controls and establishes the long-term soil and groundwater environmental quality data in Miaoli County as a reference for the subsequent relevant management policies. And the need to properly handle relevant emergency response in a timely manner in accordance with the law, to assist in the necessary actions. The work of this project mainly includes: inspection and maintenance of groundwater monitoring wells, monitoring well completion operations and foreign matter removal, site monitoring well water quality monitoring operations, pollution tracing, gas station gas detection GC analysis and map interpretation, soil water Advocate data production, regulatory briefing, and implementation of emergency response measures. The progress of each work has reached the expected planning project. A brief description of the work content and completion results of this project is as follows:
1. Conducting inspections, maintenance, well condition assessment and re-completion work for the regional and field-based groundwater monitoring wells in the county, and improving the monitoring well function to grasp the trend of groundwater quality change and achieve the purpose of preventing or monitoring groundwater pollution. Protecting increasingly valuable groundwater resources
1. The 107 monitoring well inspection work has been completed, and 22 well body maintenance and renewal and 11 well body facilities repairs have been carried out.
2. The monitoring well list and information are updated.
3. Five standard monitoring wells have been completed and five foreign bodies have been removed.
4. 33 photographic and micro-water test work and 16 re-completion operations have been completed and 16 well completion photography work has been completed.
2. Handling the water quality monitoring operation of the site monitoring well as the mastery and early warning of the current pollution situation
1. The field-based monitoring well has completed the sampling and testing operation in the dry season. The results show that the monitoring wells in the second area are downstream of the industrial zone and between the Guangyuan Science Park and the Zhunan Science Park. The monitoring wells in the second area have VOC exceeding the regulatory standards, and a few The test items and some of the monitored water quality have exceeded the pollution monitoring standards.
2. The results of monitoring wells in the remaining areas did not exceed the control standards. Only some of the monitored water quality exceeded the pollution monitoring standards. Compared with the previous years, there was no upward trend.
3. Monitoring of water quality in wells around industrial areas
A total of 16 well water quality monitoring around the first industrial zone, Zhunan Industrial Zone and Zhuke have been completed, and none of the 16 monitoring results exceeded the groundwater pollution control standards.
4. Gas analysis and map interpretation of gas leaking tube gas at gas station
The pollution potential of the gas station in the county has been sorted, and 10 stations of on-site inspection, leak detection of oil and gas detection operations and leak detection function check operations have been carried out. According to the pre-opening screening test, the FID measurement value of Parkson Gas Station is >500ppmV. The leaky tube is used for sampling sampling and for the third consecutive season, it is regularly tracked for the leak detection of the Taiya Houlong gas station.
V. Handling laws and technical seminars on promoting soil and groundwater pollution prevention and control
It has completed one session of soil and groundwater pollution regulation and guidance meeting and 10 campus storytelling activities.
6. Improve the pollution verification operation of the completed site
The site verification operation has been completed for 3 times of pollution improvement, which are respectively the No. 520 of Maqitun Section of Gongguan Township, No. 230-1 of Fuxing Section of Dahu Township and Wanxiang Tannery Co., Ltd.; among them, Maqitun Section of Gongguan Township The copper of 520 in the 520 area is 1,100mg/Kg, and the second improvement should be made according to the regulations of the soil pollution method; the verification results of the 230-1 area of Fuxing Section of Dahu Township and the verification results of Wanxiang Tannery Co., Ltd. are not exceeded. The soil pollution control standard can be dismantled after the completion of the administrative procedures. In addition, the Zhunan Plant of Haofeng Industrial Co., Ltd. did not complete the site improvement within the time limit, so the site verification was not performed.
VII. Assist in handling emergency response work for soil and groundwater pollution incidents, conduct pollution investigation, verification and related response work for sites with soil and groundwater pollution to effectively control pollution impacts and reduce or avoid site-to-environmental Possible harm
Eight times of soil and groundwater pollution emergency response work has been completed.
2. Oil spill sulphur pit oil spill event verification - THP project for soil sampling analysis did not exceed soil pollution control standards.
3. The heavy metal project of the 1-140 site of the Zhuwei section of Tonglu Township - soil sampling analysis did not exceed the soil pollution control standards.
4. Near the soil and groundwater investigation of Yixin Alloy Industry Co., Ltd. - the chromium and nickel in the bottom mud of the factory exceeded the upper limit of the sediment quality index; the zinc exceeded the lower limit of the sediment quality index. The meeting will be handled according to the rights and responsibilities.
5. Investigation of agricultural land around the foot of the Dashan Mountain - The chromium and nickel of the No. 1120-1 area exceed the soil pollution control standards, and the subsequent pollution activists or polluted land related persons shall follow the relevant provisions of the Soil Pollution Law for subsequent improvement.
6. The VOC, SVOC and PCDD projects of Jinfa Power Plant Co., Ltd. - soil sampling analysis did not exceed the soil pollution control standards.
7. Parkson Gas Station - Soil sampling analysis of the TPH project did not exceed the soil pollution control standards.
8. The groundwater sampling of No. 1182 in Yongzheng section - the volatile organic pollutants in the groundwater sampling analysis did not exceed the groundwater pollution control standards.
8. Increase the setting of the early warning network of Guangyuan Science Park and Zhunan Science Park
The project has newly established three field-based monitoring wells K00355, K00356 and K00357, and completed the in-well photography, micro-water test and particle size analysis. The measured value of K00355 TCE on the west side of the Baolai remediation site has reached 0.0179 mg/L ( The monitoring standard is 0.025 mg/L), so it is recommended to conduct regular monitoring operations for K00355 in the future to confirm whether the contaminants have spread.
IX. Announcement of business land use verification work
The project carried out two verifications of the business site verification work, namely Rohm and Haas Asia-Pacific Grinding Co., Ltd. and Jubilee Advanced Co., Ltd., in which the total petroleum hydrocarbon value of the giant company at the point S01 was 1180 mg/ L, has exceeded the soil pollution control standards, and will follow the soil pollution law for land pollution related people to improve operations.
X. Farmland pollution site for tracking of pollution sources
The project completed a total of 15 points of soil, 15 points of sediment, 15 points of runoff water sampling analysis; among them, the zinc and copper of zinc and S05 in the soil points of S01 and S02 in Haikou section of Haikou section have reached the agricultural land Monitoring standards, follow-up recommendations for regular monitoring operations. In the sediment part, the zinc, nickel, copper and chromium in the irrigation channel exceed the upper limit of the sediment quality index; cadmium, lead and arsenic also exceed the lower limit of the sediment quality index, and the follow-up letter will be requested by the Commission. Handle.
XI. Additional commitments
1. The sediment sampling analysis of the two points of the No. 520 site of the Maqitun section of the public hall has been completed.
2. One-time cross-county city observation and exchange activities have been completed.
