The overall project can be categorized into eight thematic frameworks, including regular soil contamination monitoring, high pollution potential industry guidance, groundwater monitoring and maintenance management, gas station review and on-site inspection, site inspection and verification of contaminated sites, soil or groundwater pollution verification, emergency response work, advocacy and administrative work. The results of each work are summarized below:
1. Groundwater pollution monitoring, investigation and well management: This year, the number of outward appearance inspections was 246, 13 out-of-the-way maintenance operations were carried out and 5 wells for non-monitoring purposes were used to abolish, 7 wells were repaired, 14 wells were washed. During the high and low water period at 2020, The test result of the 4 wells at 661 the Dung-guang area show that O00194 data exceeded the control standard for Trichloroethylene (0.118 mg/L), and the Trichloroethylene is an upward trend compare with last year (ND), then evaluate whether to initiate a response. If the concentration decreases, it can be monitored through MNA in the future.O00427 data also exceeded the monitor standard for Vinyl Chloride (0.0177mg/L) compare with last year (0.0192mg/L), other test results (O00358 and O00417) have not exceeded standards. The test result of the 2 wells at 981 the Dung-guang area show that O00300 data also continued to exceed the control standard for Trichloroethylene (0.0558 mg/L) compare with last year (0.0902mg/L), O00066 data was much more low than control standard for 1,1-Dichloroethylene (0.0401mg/L) compare with last year(0.0816 mg/L).
2. Tracking survey of the cancellation’s soil pollution control farmland: According to the "Principles of Periodic Monitoring of Farmland Soil", In 2020, 5 piece of farmland isn't a pollutional upward trend, it should be reduced to once 5 to 8 years. Other 22 piece of farmland can be stopped because they are below the monitoring standard of soil pollution (food crop farmland). 3 piece of farmland is a pollutional upward trend obviously for heavy metals nickel and zinc. In recent years, Environmental Protection Bureau Hsinchu has strengthened to control the factories, the pollution of farmland has been greatly reduced.
3. The management and validation of pollution improvement sites: In 2020, It is implement validation of pollution improvement sites, including three pollution improvement sites. Frist, Guang-ming Gas Station were externally verified on April 20, 2020. And, Hsiang-Shan Gas Station were externally verified on September 24, 2020. The external verification results of Guang-ming Gas Station and Hsiang-Shan Gas Station were conformed to the control targets, and they were released on August 12, 2020 and December 2, 2020 respectively. Hsin-chu Gas Station of National Petroleum Corporation were externally verified on March 27, 2020. There were still TPH concentrations of soil pollution that exceeded the control standard, pollution control site proclamation on June 12, 2020.
4. Investigation and management of underground storage tank system: Gas station reporting rate was 100%, according to EPA classification principles for different frequency tracking.The inspections comprises PID/FID detection of two gas stations and GC/FID quantitative analysis twice. PID/FID detection of Yong-fu Gas Station are all less than 1/2 warning value (250 ppmV). The FID detection at A16 of Park Gas Station of National Petroleum Corporation exceeds the legal warning value (FID>1067 ppmV), and the GC/FID quantitative analysis spectrum detected MTBE and Methane. Therefore, Park Gas Station of National Petroleum Corporation is determined to be a B1 Gas Station. In the future, PID/FID detection will be tracked every 2 months. If the data fail to reach the legal warning value for four times, the tracking will be cancelled.
5. Investigation and emergency management: The expenditure rate of emergency management was 87.33％, total funds was NT$349,320 (not taxed). Supporting projects: Soil pollution verification on January 9, 2020. Hsin-chu Gas Station of NPC were externally verified on March 27, 2020. Survey of soil for farmland around the illegal landfill site on May 4, 2020. Survey of soil for farmland complaint on May 8, 2020. Survey of soil for farmland on July 20 and July 20, 2020. Hsiang-Shan Gas Station were externally verified on September 24, 2020. Soil pollution verification for Xing-xiong Industrial Co., Ltd. on January 9, 2020.
6. Achievements of propaganda activity: Complete 1 education and training, 1 cross-county environmental protection business exchanges, 2 legal propaganda session, 5 campus promotion, 1 the course of seeded teacher of environmental education, 1 exhibition of soil and groundwater results, and support 20th EPA exhibition of Soil and Groundwater Pollution Remediation.
