The soil and groundwater pollution investigation and verification work plan of Taitung County Environmental Protection Bureau (hereinafter referred to as the Environmental Protection Bureau) is one of the important pollution prevention and control project plans every year, and the work objectives of this year include: regular monitoring of soil and groundwater quality, inspection and control of management sites, pollution verification and improvement achievement verification operations, etc., so as to achieve the goal of sustainable utilization of land resources in Taitung County.
To this end, in order to continuously grasp the status of soil and groundwater pollution under its jurisdiction, the EPB entrusted Yushan Environmental Engineering Co., Ltd. (hereinafter referred to as the team) to implement the "111 Annual Soil and Groundwater Pollution Investigation and Verification Work Plan - Taitung County" (hereinafter referred to as the Plan) in FY111, and as of November 20, 111, the overall work has complied with the contract and completed 99% of the total progress, as shown in Abstract Table 1. The results of the implementation of the work are summarized below:
1. Soil quality investigation operations
In 111 years, this plan carried out soil quality investigation operations for the 18th place of Xiabinlang section of Taitung County, the 317th place of Litai section of Beinan Township, Taitung County, the 317th place of Xinfu section of Guanshan Town of Taitung County and the 371 place number of Yongle section of Taitung City, a total of 4 land numbers, of which the soil heavy metal zinc concentration of 279mg/kg in the 18th section of Xiabinlang section of Taitung County, the concentration of heavy metal copper in soil of No. 371 in Yongle section of Taitung City was 209mg/kg, and the zinc concentration was 283mg/kg exceeding the monitoring standards for edible crops in farmland. The No. 317 of the Litai Section of Beinan Township, Taitung County, and the No. 317 of the Xinfu Section of Guanshan Town, Taitung County are lower than the monitoring standards for edible crop farmland.
2. Groundwater quality investigation operations
Changxin Gas Station, Sanxiantai Gas Station, Ruiyang Gas Station and Green Island Thermal Power Plant have completed groundwater quality investigation operations, with a total of 6 on-site monitoring wells, and the pollutants VOCs and TPH of concern are lower than groundwater pollution monitoring standards.
3. Maintenance of monitoring wells
During the year, a total of 34 monitoring wells were inspected for internal functions, inspection and maintenance of appearance, and most of them were in good condition, mainly to remove dead branches and leaves, weeds and repaint. Completed the repair of 2 monitoring well facilities (Peinan Elementary School and China Pulp Backdoor Monitoring Wells). The internal function inspection of 8 monitoring wells (4 Songfu Automobile, Green Island Auto Fishing Port Station, China Pulp Nursery, Zhihang Gas Station, Jian'an Gas Station) has been completed, and the monitoring wells with abnormal micro-water tests and photographic results in the wells have been improved.
4. Underground storage tank pollution potential inspection operations, network declaration and inspection and on-site inspection operations
In the first half of the year, Fuchi gas station, Wannian gas station, Wynn gas station, Fugang gas station, Fengsheng gas station, Meidefeng gas station, Risheng gas station, etc., the fuel machine facilities and equipment were missing oil leakage, and the repair was completed in the second half of the year.
5. Compliance with regulations and guidance for above-ground storage tank systems
In the 111 years of this plan, a total of 125 above-ground storage system regulatory compliance confirmation and guidance operations were implemented, and a total of 50 companies did not meet the control standards and did not need to be managed (such as replacing the heating system or dismantling the storage system and the capacity did not exceed 200L); The on-site above-ground storage system is equipped with spillage prevention facilities, and a total of 53 companies comply with laws and regulations; A total of 5 companies need to be improved and counseled; A total of 17 improvements were completed.
6. Soil and groundwater verification or verification and emergency response
(1) Green Island Fishing Port Gas Station Verification Operation:
TPH in soil exceeds soil control standards; The benzene in the groundwater exceeds the monitoring standard for Category II groundwater pollution, and the Taitung County Environmental Protection Bureau has asked CNPC to propose an emergency response necessary measures plan, and the improvement period is limited to one year.
(2) Verification operations of gas stations in Taipingying District:
Soil survey results TPH and Vocs were below soil pollution monitoring standards.
(3) Emergency response verification operation of Zhonghong asphalt plant:
Soil survey results TPH and Vocs were below soil pollution monitoring standards.
(4) Taitung City Taitung City Tai Sugar Zhongxing Gas Station emergency response verification operation:
The soil survey results TPH and Vocs were lower than the soil pollution monitoring standard, and during the verification process, it was found that there were foreign bodies at 1.3 meters in the oil tank area, and the PID measurement value of the station independently and continuously monitored the PID fluctuated significantly, so it was judged that the overflow of 95 unleaded gasoline did not spread outward in the protective trough.
7. Industrial park management operations
Fengle Industrial Park carried out groundwater quality sampling operation on May 24, 111, the test results FL01~FL05 groundwater sampling data were in line with the regulatory standards, Fengle Industrial Park completed the online declaration operation on July 27, the review results were normal and the records were completed for reference.
8. Handling explanations of laws and regulations, education and training meetings and press releases
This year, a total of 2 legal explanatory meetings, 2 farmers' advocacy meetings, 5 campus soil and water storytelling activities, 3 parent-child storytelling picture book publicity and 2 internal education and training sessions were completed, and 1,000 copies of advocacy masks, 600 copies of promotional towels and 400 picture books of stories were produced, distributed in advocacy activities, and 6 press releases were issued on major social platforms to expand the level of advocacy.
9. Database Updates
Based on the implementation results and within 30 days of the end of the work project, the team has transferred the results of monitoring well maintenance, water quality testing, and gas station inspections into the EPD's soil and groundwater information management system.
10. Assist in the management of the site
Based on the results of the implementation plan, the team will integrate the results of monitoring well maintenance, water quality testing, and gas station inspection into the EPD's soil and groundwater information management system within 30 days after the completion of the project. In order to make the soil and groundwater monitoring database of the Taitung County Environmental Protection Bureau more convenient for the public to operate and use, this year the web interface system was updated, the account password setting was cancelled and some testing items were added, so that the public can better understand the current situation of soil and groundwater quality in Taitung area.
11. Assist organs in handling performance evaluation operations for soil and groundwater pollution remediation
At this stage, the score of the system examination is 64.33 points, because the evaluation system has not yet included the announcement business management and local characteristic operations and soil water advocacy business in the score, and it is expected that 100 points will be scored this year.
