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 Protection Bureau (EPB) has been continuously monitoring the potential sites of contaminated soil and groundwater in the region, including industrial complex in Loung Te and Letzer, as well as other underground storage tanks (UST). Additionally, the inspection, 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 “2019 Investigation and Verification of Soil and Groundwater Contamination in 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 13 sites, where the contamination in soil exceeds the monitoring standard, were investigated. The result shows that the concentration of heavy metals were found to exceed monitoring standards in 8 sites, where some of area that the lands fertilized using animal manure and groundwater full of arsenic. In addition 1 site be analyzed the concentration of heavy metals were found to exceed control standards. 2. Contamination Potential Area Survey The total of 18 factories were Phase I surveyed and conducted soil and groundwater contamination verification of 8 of these factories were sampled. The results showed for soil and groundwater, none of these 8 factories exceeded the control standards. However, one of them are exceeded the monitoring standards, who regular monitoring is needed in the future. 3. Sediment Analysis of Industrial Area This year, PVEEC has completed sediments analysis around the potentially-contaminated factories, a total of 4 factories in Loung Te and Letzer industrial area. Results showed that the many of heavy metals in the sediment exceeded the “Sediment Lower Limit”, even exceeded the “Sediment Upper Limit”. There is an increasing trend with downstream of the regional drainage. 4. Groundwater Analysis Sampling work of all 19 wells has been done in May, 2019, and no results exceeded the control standards, and 6 of them reached the monitoring standards, mainly ammonia nitrogen. As for the monitoring of the landfill site, no groundwater exceed the control standards. It is common that all landfills detected ammonia nitrogen and total dissolved solids(TDS), exceeding monitoring standards. For raw water, Wujie, Su-Ao and Samxing Landfill all detected ammonia nitrogen, exceeding the discharge water standard. 5. Wells Maintenance and Checking The team had completed, as contracted, 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, and 1 of it was stopped monitoring. In addition, for the condition assessment on 11 monitoring wells; according to the results, 5 of them went through the internal maintenance after the assessment, and 6 of them went through the well development again followed by camera shooting inside the well to assure of tidiness. 6. Restrained Sites Management and Verification The PVEEC has completed 32 site-related written reviews and 10 soil and groundwater legal-related written review; also assisted in 8 review meetings and 1 On-site checking. 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 8 sites that has completed post-improvement verification, and 7 of them have been removed from the control list. 7. UST Online-review and Checking The PVEEC has been associate with EPB to complete the UST reports of Q3 in 2018 (from Sep to Dec), Q1 in 2019 (from Jan to Apr) and Q2 in 2019 (from May to Aug), with 100% of inspection. We also monitored gas stations of 6 UST, and Under the known condition soil and groundwater investigation started at Guang-Jin gas station, the outcome told no sight of exceeding the control standards. 8. Emergency Response and Others There had been 12 Lorries going through the examining work of soil-rock importing management. Amid the use of XRF screening, the selected samples were analyzed for heavy metal content and the results indicated all sample standards compliant. 9. Event Handling and Routine Business This year, there have been completed 3 open conferences for interpreting relevant Acts of prevention of soil and groundwater contamination (total audience number: 242), 5 educational sessions and 1 training courses (total audience number: 360). The team has also assisted the environmental education activities on 2019/10/6 (total audience number: 3200). For the evaluation of performance indicators, the team has assisted the EPB in proposing key points and measures of the 2019 evaluation for program management, contaminated site management and administrative works, highlighting the determination of the EPB in contamination verification and remediation and showing the effectiveness 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 in addition to the principle of mastering the basic scores, as of December 20, 2019, the score of EPB's performance was 83.35.
