2022 Investigation and Verification of Soil and Groundwater Contamination in Yilan County

Absrtact
1. Simultaneous sampling of soil and crops The project has cooperated with Agriculture department to finished simultaneous sampling of soil and crops . Because the crops aren ’t abnormal , so no soil analysis required. 2. Contamination Potential Area Survey The total of 7 factories and 3 military installation has already investigation(Phase I surveyed) this year. In these factories or military installation,the project choce3 factories and 1 military installation those moer potential to soil and groundwater contamination verification . The results showed that Cu(264 mg/kg mg/kg) in soil concentration of “SIN-SHAN Company” have exceeded the moni toring standard; the military installation called “GUANG SYUA rsenal ” Pb (0.347mg/kg) and Cr(0.261mg/kg) exceeded the control standards and monitoring standard respectively. 3. Groundwater Analysis Sampling work of all 22 wells has been done in May, 2022, and the results have 2 well ground water exceeded standards(G00206, G00231)and 9 wells groundwater exceeded monitoring standards. 4. Wells Maintenance and Checking The project 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 , 2 facilities of wells has been repaired; 2 of it was abolish. 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 fol lowed by camera shooting inside the well to assure of tidiness. 5. Rest rained Sites Management and Verification The PVEEC has completed 30 site-related written reviews.The PVEEC has carried out the monthly inspect ion over restrainedsites 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 5 sites that has completed postimprovement verification.The PVEEC has completed 13 soil and groundwater legal-related written review, 10 soil and groundwater legal-related on-site inspection. 6. UST Onl ine- review and Checking The PVEEC has been associate with EPB to compl ete the UST reports of Q3 in 2021 ( from Sep to Dec) and Q1 in 2022 ( from Jan to Apr )and Q2 in 2022 (from May to Aug), with 100% of inspect ion. We also had monitored gas stations of 15 UST. Because received EPA instruct ions to stop the soil and groundwater investigation this year. 7. Storage system counseling and investigation The project has counselling survey completed 51 enterprises which have storage system. We have been investigating 15 undergroung storage system. 8. Emergency Response As of December 2022, sampling work has completed 5 times of vehicles and 6 pointsoil in the terminal processing, and no results exceeded the control standards.Until October 31 2021, the team has executed 7 emergency response. 9. Event Handling and Routine Business This year, there have been completed 1 conferences for interpreting then ewlaw “Regulat ions for Instal lat ion 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 the Article 8th and 9th Regulations on Soil and Groundwater Pollution Remediation Law (total audience number: 59); 10educat ional sessions and 1 training courses (total audience number: 572). The PVEEC has also filming the video based on the work of this project . For the evaluat ion of performance indicators, the team has assisted the EPB in proposing key points and measures of the 2022 evaluat ion for program management , contaminated site management and administrative works, highlighting the determination of the EPB in contamination verification and remediation and showing the effect iveness of soil and underground water implementation.
