Since Environmental Protection Department, New taipei City Government (NTC-EPD) implemented the program of soil and groundwater pollution investigation and verification in 2004, it has continuously monitored the quality of soil and groundwater, and implemented necessary response measures to eliminate pollution from the source and the end.
About the part of groundwater monitoring wells in this program, we have done the maintenance works. It is recommended to apply warning paint around all of the wells.
In terms of groundwater quality monitoring, two wells of Jhengtai have been found mercury exceeded the standard in the first half of this year but down to normal in the next half of this year. Shulin Industrial Park is mainly polluted by cis-1,2-DCE and VC. This year, it was confirmed that the pollution has moved downward to 10 meters below the ground. When trying MNA next year, we may be able to adjust some parameters by referring to this depth, the experience of groundwater pollution remediation in the New Taipei Industrial Park, or the experience of EA in Miaoli County Government.
For this year's storage system work, we have examined all of the online reports, provided face-to-face guidance, monitored leak detection wells, inspected on-site facilities, and analyzed soil gasses with GC/FID. If the collecting-sump emission oil gas, it should be put on the list of concerns for next year.
This year, we have co-organized a course for elementary school students with NTC-EPD. Other policy promotion activities have been held for the factories controlled by Articles 8 and 9 of the Soil and Groundwater Pollution Remediation Act, the storage systems, Optoelectronics Market, and the groups A and B. It is recommended that NTC-EPD refer to the responses to this year’s questionnaire when conducting publicity activities next year.
Photovoltaics were promoted for all of Pollution Control/Remediation Site in New Taipei City. But positive feedback was never received. Members of the review committee recommended that central and local environmental departments should work together to discuss the incentives.
38 soil pollution assessment investigation reports have been reviewed, and 35 on-site inspections have been conducted.
Cooperate with Environmental Management Administration to conduct a two-stage review of 6 environmental engineer visa reports. The final result of the missing points was sent to each environmental engineer for quality improvement.
For 50 Pollution Control/Remediation Sites in New Taipei City, on-site inspections are carried out 1 to 2 times a month, , and check GSR and BMPs at the same time. This year, 4 sites were verified, but only 1 site passed the assessment. It show the fairness and rigor of NTC-EPD.
We have reviewed aboveground storage system improvement operations and confirmed regulatory compliance for underground storage systems.
The routine of preventi soil pollution in agricultural land and the traceability investigation of water pollution in irrigation channels where sediment over the Soil Pollution Control Standards have been completed. The concentration of heavy metals in the sediment in Shih Tou irrigation canal exceeded the upper limit of the sediment quality guidelines. The concentration of heavy metals in the sediment in the Er Jia Jiou irrigation canal exceeded the Soil Pollution Control Standards. NTC-EPD will investigate the possible sources of contamination.
The enterprise's soil and groundwater pollution prevention and management operations have been completed. After certifying 4 companies of Group A, it was found that heavy metals or TPH exceeded the Soil Pollution Control Standards. It shows that this pollution prevention and management operation has effectively discovered soil or groundwater contamination.
We have proposed two innovative plans and have implemented them. One is ‘Tracking whereabouts of off-site soil’, the other is ‘Soil pollution potential map combining factories and irrigation canals’. After improvements, it can be used continuously in the future.
About emergency works, we have monitored the groundwater qualities of specific sites; repaired 6 buried monitoring wells; the preparatory works for MNA, which will be carried out in Shulin Industrial Park in 2024; investigated the groundwater quality of Shulin Industrial Park, Zhongxing North Street in Sanchong District, and Lane 515 in Section 1 in Datong Road in Xizhi District.
