台灣美國無線電股份有限公司(RCA)原桃園廠地下水污染整治場址之應變必要措施計畫

中文摘要 台灣美國無線電股份有限公司(以下簡稱RCA公司)原桃園廠於91年4月26日公告為地下水污染控制場址,其後於93年3月19日由行政院環保署公告為地下水污染整治場址,其地下水污染整治計畫書於98年10月26日由環保署同意備查,並開始執行18個月地下水污染整治作業。RCA公司歷經18個月使用加強還原脫氯法(ERD)無法整治至地下水污染管制標準,乃於100年5月6日提出變更及展延計畫書,內容說明展延6個月。該變更計畫於100年8月16日同意,展延期限至民國101年2月15日。RCA公司又於101年1月13日再次提出展延變更計畫,期程為102年6月24日(第二次變更核定日)起再展延2年。而104年5月21日RCA公司再提出展延三年之整治計畫書變更計畫(第三次變更)。 桃園市政府環境保護局在RCA場址下游區域已測得多處地下水監測井遭受污染,為減輕污染危害或避免污染擴大而影響人體健康、農漁業生產或飲用水水源等,採取應變必要措施,並釐清場址內污染是否擴散至場址外,並同時調查、控制及監測場址外地下水污染範圍,爰辦理本應變必要措施計畫。主要工作分為下列項目。 (一) 依整治計畫書之內容,確實執行,每周派員至整治場址,詳實記錄、照相及攝影等相關作業,期以提供作詳盡之資料,俾利監督小組判讀。 (二) 場址外地下水質採樣分析方面,103年本計畫進行新設2口地下水井及既有16口地下水井監測,於104年本計畫再新設2口地下水井,並配合既有18口地下水井(含103年新設2口監測井)進行監測,其中MW-15-RCA因道路鋪設柏油導致井體阻塞無法採樣,故103年及104年實際採樣井數分別共計17口及19口,上述之監測井均於枯豐水期採樣。本計畫截至104年10月底已完成4口次監測井設置,並已完成4次地下水採樣分析。另針對管制區內民井,亦完成民井訪查及2次共20口次採樣分析,並彙整本計畫與整治單位之監測結果,藉以掌握污染情形及程度,以確保污染範圍無擴大。 (三) 組成應變支援單位辦理緊急污染案件及相關管制作業,避免於整治工程執行過程中,因污染擴大或惡化而危及附近居民之健康及影響環境品質。

Emergency Measures for RCA Former Taoyuan Plant Groundwater Remediation Site

英文摘要 TCETVT (hereinafter referred to as RCA) former Taoyuan plant was announced as Groundwater Pollution Control Site on April 26 2002 and Groundwater Remediation Site was further announced on March 19 2004 by EPA of the Executive Yuan. The Site Groundwater Remediation Plan was agreed on October 26 2009 by EPA, and started the 18-month groundwater remediation work. After 18 months of applying the enhanced reductive dechlorination (ERD) technology, site groundwater still could not meet the Groundwater Pollution Control Standards. Therefore, on May 6 2011 a plan amendment requiring a six-month extension was applied by RCA. This first amendment was approved on August 16 2011 with extended new due date of February 15 2012. RCA again on January 13 2012 applied another 24-month extension starting from June 24 2013 (the date second amendment approved). Currently, RCA has applied the third plan amendment application with extension of 3 years on May 21 2015. Taoyuan City Department of Environmental Protection (DEP) has found several monitoring wells which located at downgradient of RCA site are contaminated. To minimize or avoid the impact of human health, agricultural or aquaculture production, or drinking water sources, necessary response measures will be conducted. In the meantime whether onsite contamination has spread to offsite will be clarified. The inspection, control and monitoring of offsite contamination area should be performed in parallel. This project is to ensure that RCA site remediation work properly executed, focusing on RCA onsite and offsite remediation effectiveness and delineation of offsite groundwater contamination. The project is divided into following parts: 1. This project monitored the remediator’s remediation activities according to the scope of approved Plan, weekly site walk through, documentation of site logs, photography and photographic and other related operations of the period were also conducted in order to provide detailed information for oversight committee. 2. In 2014, offsite groundwater at total 17 monitoring wells were sampled and analyzed, among them included 2 new wells and 15 existing wells (well MW-15-RCA damaged and could not be sampled). Two another new wells and 17 existing wells were sampled and analyzed in 2015. As of the end of October 2015, project has been completed installation of four monitoring wells, completed four groundwater sampling events and analysis which covered the consecutive wet and dry seasons. Regarding the residential wells located in control zone, project also completed the survey and visiting of residential wells. A total of 20 wells per year sampling and analysis were conducted. All onsite and offsite monitoring results were collected and analyzed in order to have site current status and extent of contamination, and as a reference to the subsequent risk management. 3. Establishing a response team that assists DEP to investigate and control the incidents of pollution to avoid the pollution spreading or deterioration during remediation. Therefore the health of nearby residents and environment can be protected.
