In order to prevent soil and groundwater from contamination, the local competent authority must regularly investigate and exam the quality of soil and groundwater in its own jurisdiction and deal with the petitions.
Therefore, Yilan Environmental Protect ion Bureau(EPB) has been continuously monitoring the potentialsites of contaminated soil and groundwater in the region, including industrial complex in LoungTe and Letzer, as well as other underground storage tanks (UST). Additionally,the inspect ion, verification and control measures has been implemented
over restricted contaminated area. The Yilan EPB has commissioned Pro.
Vision Environmental Engineering Corporation(the“PVEEC”) to be the chief executive of the “2021 Investigation and Veri fication of Soil and Groundwater Contaminationin Yilan County” project(the “project”). All scopes of work in the project has been accomplished and every assignment was flawlessly on schedule. Hereby the final report is submitted to the EPB following its inspection over the work .
1. Soil Reguler Analysis
This year, a total of 10 sites, where the contamination in soil exceeds the moni toring standard, were invest igated. The result shows that the concent ration of heavy metals As(62.8mg/kg) were found to exceed monitoring standards in 1 site, where some of area that the lands irrigated using groundwater full of As. Other 9 sites were complied with
monitoring standards.
2. Contamination Potential Area Survey
The total of 9 factories were Phase I surveyed and conducted soil and groundwater contamination verification of 5 of these factories were sampled.The results showed that Cr(727、644 mg/kg) concentration of“SHI-HUNG Company” have exceeded the control standards ; thatCu(1450、1300、1200 mg/kg) , Zn(2450、2460 mg/kg) and Cr(1040、302、302 mg/kg) of TIEN-YU Company exceeded the control standards; thatCu(831、645mg/kg), Cr(1040、302、302 mg/kg) and Ni(376 mg/kg) in soil
with Zn(478 mg/kg) in mudconcentration of “RUEI JHAN MACHINERY Company” have exceeded the control standards.
The sampled results of “C.P.C.Corporation of Suao Provide Oil Center” was complied with monitoring standards.
3. Groundwater Analysis
Sampling work of all 23 wells has been done in May, 2021, and the results have 9 wells groundwater exceeded monitoring standards.
4. Wells Maintenance and Checking
The team had completed, as cont racted, a total of 2 times of quarterly work of the checks and maintenance of regional and on -site monitoring wells , according to the results, 5 of them went through the external maintenance after the assessment , 3 facilities of wells has been repaired; 1 of it was built . In addition, for the condition assessment on 10 monitoring wells; according to the results, 5 of them went through the internal maintenance after the assessment , and 5 of them went through the well development again followed by camera shooting inside the well to assure of tidiness.
5. Restrained Sites Management and Verification
The PVEEC has completed 28 site-related written reviews.
The PVEEC has carried out the monthly inspection over restrained sites for the progress of improvement and the latest condition in hand and evaluate the predicted effects for the site where the remediation plan has been accomplished. Currnently, there are totally 1 sites that has
completed post -improvement verification.
The PVEEC has completed 8 soil and groundwater legal-related
written review, 10 soil and groundwater legal -related on-si te inspection.
6. UST Online- review and Checking
The PVEEC has been associate with EPB to complete the UST
reports of Q3 in 2020 ( from Sep to Dec) and Q1 in 2021(from Jan to Apr) ,with 100% of inspection. We also monitored gas stations of 16 UST, and Under the known condition soil and groundwater investigat ionstarted at“Dong-ao” ＆ ” Wu-jie” gas stations, the result were complied with monitoring standards.
7. Storage system counseling and investigation
The PVEEC has counselling survey completed 107 enterprises which have storage systems Among them, 43 companies need to propose improvement plans , 2 companies were sampled. The results showed that was complied with monitoring standards .
8. Emergency Response
As of December 2021, sampling work has completed 12 times of
vehicles, and no results exceeded the control standards.Unti l December 31 2021, the team has executed 6 emergency response .
9. Event Handling and Routine Business
This year, there have been completed 2 open conferences for
interpreting the new law “Regulat ions for Instal lation and Management of Facilities for Preventing Pollution of Groundwater Bodies and Monitoring Equipment in Underground Storage Tank System” (total audience number:101), 1 conferences for military unit for interpreting prevent ion of soil and groundwater contamination(total audience number : 10) , 10 educational sessions and 1 training courses (total audience number: 470).The PVEEC has also filming the 2 sand painting animations of soil and groundwater story
For the evaluation of performance indicators, the team has assisted the EPB in proposing key points and measures of the 2021 evaluat ion for program management , contaminated site management and administrative works, highl ight ing the determinat ion of the EPB in contaminat ion
verification and remediation and showing the effect iveness of soil and underground water implementation. In addition, the team also assists the EPB in setting relevant weights for assessments , giving higher weights to projects with higher levels of confidence, in order to achieve the highest
scores inaddition to the principle of mastering the basic scores, as of season 3, 2021, the score of EPB's per formance was 77.84. But before the deadline, we can get 98.5 points in our own assessment .
