摘要

有機溶液的使用在工業發展過程中扮演著不可或缺之角色，然而有機溶液所造成地下地層之污染，常見以非水相液體之污染居多，當中又可分為比水重之非水相液體（Dense Non-Aqueous Phase Liquid，DNAPL）和比水輕之非水相液體（Light Non-Aqueous Phase Liquid，LNAPL）兩類。以往地下污染之檢測方式採用破壞性檢測(Destructive Surveying)施作，如鑽孔取樣、傳統電流地電阻探測法…等，然而此方式受限於現地條件，且耗費人力及成本；因此，本研究將使用非破壞性電容耦合地電阻系統（Capacitively Coupled Resistivity System）來施作地下污染範圍之檢測。
本研究中將以現地實際污染之案例來施測分析，依據非破壞性電容耦合地電阻系統之探測方式，將施測之成果，經由反算程式求得之視電阻率擬似剖面圖，用以研判分析並描繪出污染區域之範圍，最終再以現地鑽探報告及透地雷達施測之成果相互比對，用以驗證非破壞性電容耦合地電阻探測污染之可信度。

The use of organic solutions has been playing a crucial role in industrial development. However, these solutions are known to be the source of common underground contamination, most of which are the result of non-aqueous phase liquids. These liquids can be further categorized as Dense Non-Aqueous Phase Liquid (DNAPL) and Light Non-Aqueous Phase Liquid (LNAPL). In the past, the tests for underground contamination were carried out with destructive surveying methods, such as drilling and sampling, conventional electric resistivity probe, and yet this type of methods are often limited due to site conditions and known to be manpower and cost-consuming. Therefore in this study, a nondestructive capacitively coupled resistitvity system is introduced for the survey for the extent of underground pollution.

In this study, several cases of pollutions happened in real life are explored for analysis using the survey method suggested in nondestructive capacitively coupled resistitvity system. Then the survey results are analyzed using apparent resistivity psuedosection obtained from reverse modeling program and the extent of contamination is plotted. At the end, the results are compared with the bore logs and the ground-penetrating radar survey report to verify the credibility of using nondestructive capacitively coupled resistivity system in contamination survey.
