中文摘要 | 非飽和層中之CaCO₃溶離及鹽基交換反應會影響地下水質之Na/Cl比,鹽分污染亦之。本研究選擇宜蘭縣新馬地區之17口淺層地下水井,進行兩次採樣,分析地下水中之主要成分,應用Na/Cl比來追蹤鹽分污染情形。其結果顯示,雖然在評析水質結構及鹽分污染來源方面,Na/Cl比並無法取代Piper's水質菱形圖及Collin's水質柱狀圖,但Na/Cl比可正確指出鹽分污染井,故可作為地下水質之重要參數。而以其作為一鹽分污染指標,也比電導度值或氯鹽明確。因此,在一個均勻相的非飽和層,使用Na/Cl比追蹤鹽分污染是很好的選擇。 |
英文摘要 | The CaCO₃ dissolution and base exchange reactions in unsaturated zone affect the Na/CI ratios of ground water qualities. Contamination of salinity also has the same effect in changing the ratios. Seventeen shallow wells in Shin-Ma region, I-Lan County were selected for double samplings to analyze the principal components of groundwater. The use of Na/CI ratios to trace salinity contamination in shallow groundwater was carried out. The results show that although the Na/CI ratios can not replace Piper's triangle and Collin's bar charts for evaluating the water quality structure and tracing salinity sources, it may serve as an important parameter to point out wells with salinity contamination exactly. As an indicator of salinity contamination in groundwater, the Na/CI ratio is more definite than E.C. or chloride. Therefore, in a homogeneous unsaturated zone, it is a favorable choice to use Na/CI ratios to trace salinity contamination in groundwater. |
