中文摘要 | 本研究主要目的在於了解中港地區地下飲用水質之污染情形、居民用水特性、比較該區地下水與自來水質之差異性、及可能污染原因。在居民用水特性調查方面,採電話簿等距抽樣之電話問卷,共得399份有效樣本; 在飲用水質之污染調查方面,採到戶現場採樣,共完成地下水79個、自來水22個樣本。本研究共分析14項水質項目,採樣分析方法使用行政院環保署頒布之標準方法。 結果研究可發現地下水質明顯比自來水質差,尤以大腸菌類檢出者高達56%、色度、濁度、亞硝酸鹽、鉛、錳、鐵亦分別有12.7%以上之不合格率。尤其亞硝酸鹽與鉛對於人類是有毒物質,且經過一般濾水器亦無法有效降低濃度。 本研究顯示民眾尚未養成珍惜水資源之習性,而近年來臺灣地區身受缺水之不便,因此建議透過傳播媒體、教育體系、民間環保團體加強對民眾之環保教育。政府更應致力於提高自來水普及率,考慮提高長期偏低之水費,並督促水廠提高供水品質,以保障大眾之健康。 |
英文摘要 | The purpose of this study was to assess the quality of groundwater for drinking in Taichung Harbor area and to identify the possible factors of contamination. A field sampling was conducted in 101 families with 79 drank from groundwater and 22 drank from tap water. Fourteen items of water pollution index be analyzed in this study. The results indicated the quality of groundwater is worse than tap water, especially the positive rate of E Coli. Was nearly 56% compare to 22.7% of tap water? The unqualified rate of turbidity, color, and nitrite nitrogen, Pb, Mn, and Fe were all more than 12.7%. The results further showed for groundwater. The concentration of nitrite nitrogen is related to house type. And the value of turbidity and color have a correlation with the concentration of Fe and Mn. |
