The "Soil and Groundwater Pollution Investigation and Verification Work Plan" of the Taitung County Environmental Protection Bureau (hereinafter referred to as the Environmental Protection Bureau) is one of the important annual pollution prevention and control projects. The work objectives of this year include: regular monitoring of soil and groundwater quality, Site inspection and control, pollution verification and improvement results verification operations, etc., to achieve the goal of sustainable use of land resources in Taitung County.
To this end, the Environmental Protection Agency, in order to keep abreast of the soil and groundwater pollution in its jurisdiction, commissioned Yushan Environmental Engineering Co., Ltd. (hereinafter referred to as the team) in 109 to implement the "109 Soil and Groundwater Pollution Investigation and Verification Work Plan-Taitung "Counties" (hereinafter referred to as this plan), the overall work is in compliance with the contract requirements, and the total progress is 100%. See the summary table for details. The results of various tasks are summarized as follows:
1. Soil quality survey operations
The farmland around Fengyi Ranch (No. 71, Shemagan Section, Taitung City) and chicken manure farmland (No. 1117, Banjiu Section, Beinan Township, Taitung County) are below the monitoring standards for food crop farmland. It is suggested that next year, we can follow the agricultural land with high cumulative increase rate of Cu and Zn in biogas residue and biogas slurry in one year as the basis to strengthen attention and control, and conduct soil heavy metal verification operations when necessary.
2. Groundwater quality survey operations
The VOCs and TPH of the 11 secondary pollutants of concern at Lanyu Thermal Power Plant, Malan Gas Station, Fengli Gas Station, Changxin Gas Station and Sanxiantai Gas Station are all lower than the groundwater pollution monitoring standards. It is recommended to target Lanyu Thermal Power Plant V00064 The concentration of iron and manganese in the groundwater should be noted and confirmed.
3. Maintenance of monitoring wells
In this year, a total of 35 monitoring wells have been inspected for internal functions and appearance inspections and maintenance. Most of the monitoring wells are in good condition, mainly for removing litter, weeds and repainting; completing the restoration of 6 monitoring wells (Beinan Elementary School) , Zhiben Elementary School, Giant Resource Recovery Plant, Tofu Shop, Ludao Thermal Power Plant-3 and Zhihang Gas Station Monitoring Well). Completed 6 internal functional maintenance operations (Guanshan Elementary School, Fuyuan Elementary School, Zhiben Elementary School, Luye Elementary School, Fengli Elementary School, and Renai Elementary School), and improved monitoring wells for abnormal water test and well photography results Completed; Completed the abolition of 3 monitoring wells, including V00058 (Taiwan Railway Administration), V00059 (Luye Gongsuo-1) and V00091 (Xia Nanliao Section 400).
4. Pollution potential check of underground storage tanks, online reporting and checking, and on-site inspections
This year, the online declaration and verification have been completed. Only one person in charge of the Dafugang gas station has disappeared due to debt problems. The creditor requested the court to seize all the property under his name. Therefore, the declaration has not been completed. A total of 8 stations have been reviewed. Anomalies, including Malan, Fuchi, Xingsheng, Ruiyang, Nanhui, Zhucheng, Taitung, and Dongjin gas stations. The main problem is that the oil storage data does not match due to incorrect values. All of them have been improved and completed. After verification, it was judged that there was no concern about pollution; during on-site inspections, it was found that the facilities and equipment of 4 stations were missing, including Zhihang, Haiduan, Malan and Chenggong gas stations, mainly because of the unclear labeling of leak detection tubes, the number of fuel guns, and the underground storage tank The basic system information is inconsistent, the bottom of the tanker has oil stains, and the bottom pan coating is peeling off. After counseling, the improvement has been completed, with an improvement rate of 100%; 20 gas station leak detection tube inspections and 2 GC points have been completed. The inspection results show Wynn The gas station's pollution potential is classified as A, and after verification, it is determined that there is no concern about pollution. It is recommended that next year, Haiduan, Malan, Ruiyang and Dafugang gas stations, as well as other long-term, poorly managed businesses, should pay more attention to control.
5. Soil and groundwater inspection or verification and emergency response
(1) Zhihang Base: The groundwater survey results of monitoring wells are all below the groundwater pollution control standards.
(2) Fengli Gas Station: The soil survey results are all below the soil pollution monitoring standards.
(3) Ruiyang Gas Station: After the first verification, it was found that the naphthalene in the groundwater simple well was 0.351mg/L, which exceeded the groundwater monitoring standard, and the total petroleum hydrocarbon was 33.4 mg/L, which exceeded the groundwater control standard. Please immediately ask the operator to take emergency measures. Contingency measures were taken, and a standard well was set up at the cost of emergency response. After the second verification, the soil and groundwater concentrations were lower than the monitoring standards.
(4) 798 and 761 of Xipu Section of Guanshan Town: The soil concentration is lower than the soil pollution monitoring standard.
(5) Numbers 493 and 494 of Xinyuan Section, Taitung City: The soil concentration is below the soil pollution monitoring standard.
6. Handle regulations, education and training meetings and press releases
This year, we completed 2 legal briefings, 2 farmer publicity meetings, 2 internal education and training sessions, and 8 school publicity activities, and produced 600 publicity materials, 2 hanging scrolls and 400 story books for distribution at the conference. In addition, issued 5 press releases, participated in radio stations to expand the level of publicity, and completed assisting the Environmental Protection Agency to cooperate with the 20th anniversary of the Soil and Groundwater Pollution Remediation Fund Management Meeting to handle the exhibition and exhibit production planning and reporting.
Seven, database update
The team has incorporated the results of monitoring well maintenance, water quality testing, and gas station verification results into the soil and groundwater information management system of the Environmental Protection Agency based on the implementation results and within 30 days after the end of the work project.
8. Assist in managing the site management
The total number of polluted sites in this county is one remediation site, which is the gas station at Ludao Fishing Port. The inspection operation from January to December has been completed at this stage, and the work of the SGM system has been recorded and uploaded for the EPA's reference.
9. Assist the agency in handling the performance evaluation of soil and groundwater pollution remediation operations
At this stage, the system test score is 82.5 points, because the evaluation system has not yet included the announcement business management, local characteristic operations, and soil and water promotion business into the score, it is expected to get 99.5 points this year.
11. Other
The team has completed the commitments for the selection, and completed two-point XRF screening operations for the soil quality survey operations (Fengyi Ranch and No. 1117, Peinan Township).
