為掌握國內高污染潛勢工業區之土壤及地下水品質狀況，行政院環境保護署委辦「高污染潛勢工業區污染源調查及管制計畫（第一期）」。選擇北部兩工業區，苗栗縣頭份工業區及桃園縣中壢工業區為調查目標。 現場調查分兩階段進行，第一階段包含工業區內、外之地球物理、地質鑽探等水文地質調查作業，以規劃地下水監測井位置及採樣分析作業；另外透過工廠實地的現勘與訪談，評估工廠之污染潛勢，列出調查名單，藉由地球物理方法調查，評估高污染潛勢區進行地下水監測井設置與採樣分析。第二階段則依前述調查成果，探討污染物分佈範圍與濃度變化趨勢，進行污染源研判。 調查結果顯示，頭份工業區地下水污染深度已達第二含水層(約86公尺)，污染範圍涵蓋頭份工業區西側、永貞國小西南側及西側，污染物種類包含苯、氯乙烯、三氯乙烯、1,1-二氯乙烯、順-1,2-二氯乙烯、反-1,2-二氯乙烯等。中壢工業區內多處監測井地下水中發現三氯乙烯污染物，其中以北區(工業局監測井CL02附近)較為嚴重；依本計畫調查所觀測之區域地下水流向，初步研判環保局監測井H00258(內定國小)與工業局監測井CL02所測得之三氯乙烯污染應為獨立之污染源。而中壢工業區內所測出多種含氯有機物，亦顯示工業區內可能仍存在多處不同性質之污染團存在。

In order to understand the soil and groundwater qualities in industrial parks, EPA initialed the project ”Contamination Source Investigation and Mitigation Plan for Industrial Park of High Contamination Potential (I)”. Two industrial parks, Toufen and Jhongli, were selected as targets in northern Taiwan. In this project, the investigation included two stages. At the first stage, geophysical surveys, geological drilling, well installations, and groundwater sampling were conducted in the surrounding areas of the abovementioned industrial parks. Meanwhile, after completing questionnaire surveys and interviews, higher pollution potential factories located in the industrial parks were selected, and geophysical surveys, well installation, as well as groundwater sampling were subsequently conducted. Based on the results of the first stage, the extent of contamination, concentration trends, and hot spot locations were evaluated. The results indicated that the pollution in Toufen area has already reached the second aquifer (about 86 meters below ground surface) and has extended to the west side of the Toufen Industrial Park and southwest to west of YungJen Elementary School. The contaminants included benzene, vinyl chloride, TCE, 1,1-DEC, cis-1,2-DCE, and trans-1,2-DCE. In the Jhungli Industrial Park, TCE was the main contaminant found in several groundwater monitoring wells. The maximum concentration of TCE was detected in Well CL02 located at north of the park. According to the groundwater analytical results and the regional groundwater flow direction, it was suggested that TCE within Well H00258 and Well CL02 might be from different sources. The results also indicated that several chlorinated contamination plumes might be located in the Jhungli Industrial Park.
