Taichung Environmental Protection Bureau (TCEPB) has carried out the work to manage the current quality of soil and groundwater, including regular monitoring, emergency treatment and investigation, verification for soil gas near underground storage tanks, testifying pollution sites, management and maintenance of monitoring wells, and educational campaign. In 2019, TCEPB has commissioned AECOM to run “2019 Project of investigating and verifying pollution for Taichung soil and groundwater” (the “project”), and the working period was from January 9th 2019 to December 20st 2019. The following abstract is the interpretation of the project.
In 2019, we have successfully completed groundwater sampling for 3 wells in both drought and monsoon seasons, the result indicate the concetration of Cr has not decreasing.
In first half year, we have completed exterior and interior patrol and inspection for 214 monitoring wells and 210 in the last half year. Other results including condition evaluation for 39 wells, i.e 4 area wells and 35 site-placed wells , maintenance of 20 monitoring wells, repairing body facility for 10 wells, rebuilding 20 wells, eliminating unexpected substance and photography for 5 wells.
The project in 2019 has verified 8 fields and only 1 of them is qualified. The reasons of failing to qualify may be imperfect site investigation in early time, suggesting that the sites be in control list and make pollution range clearly.
There are 316 (January), 315 (May) and 315 (September) underground storage tank industries have to complete online application, separately. Our team finish the verification in February, June and September. Both the percentage of application and verification are 100%. According to the pollution potential classification of underground storage stank which is completed by our team, the team has selected 14 highly potential polluted underground storage for verification. Among selected high pollution potential underground storage tanks, there are 4 stations which concentration of soil gas is still higher than regulatory warning standards and 2 of them are belong to level A, and 2 of them is level B1 in a row from followed examination results.
As of 20th December 2018, our team have completed 4 soil and groundwater emergencies treatment works. The total funds is 604,614 NTD.
Our team assisted TCEPB holding 1 groundwater storage tank laws explanation session , 1 environmental regulation workshop, 15 campus educational propagandas and 1 soil and groundwater remediation camp for high school students. The amount of all activities participants conform to contract and the results of questionnaire shows high satisfaction. Because Report of Investigation and Detection in Soil Pollution will review by TCEPB, our team establish a process of review and memo and set up a website to advocate Article 8 and 9 in Soil and Groundwater Pollution Remediation Act. Besides, 37 reports are 100% reviewed and reduce the time of review from 40 days to 35 days with our help.
