中文摘要 | 本文調查雲林離島工業區附近地下水水質,一共鑽鑿21口淺層水質觀測 井,井深20~25公尺,分兩梯次取樣,水質檢驗項目25項,包括一般項目18項及 重金屬7項。沿海地區各井之氯離子、鈉離子、總溶解固體及電導度均偏高,海 水入侵情況嚴重,尤以口湖、台西及麥寮等地區為甚,已不適合民生用水及灌溉 用水。而200公尺以下深層地下水水質尚未受到海水入侵之污染,僅在地下水水 位下降最多之口湖鄉水井,部份氯離子及電導度略高,可能是經由淺層地下水濃 度較高之水質擴散入滲至深層所致,故離島工業區用水應以不使用地下水為規劃 方向,以減緩海水入侵、地下水鹽化及地盤下陷,並應長期監測地下水水位、水 質,防止地下水水質惡化達到保護地下水資源之目的。 |
英文摘要 | The study focus on the investigation of ground water quality inthe area of Yu-Lin offshore Industrial Park. 21 shallow monitor wellsrange from 20 to 25 meters were drilled. Two batches ground watersamples were collected. Totals of 25 items were analyzed whichincludes 18 general items and 7 heavy metals. The result of [Xa+],[CI-], total dissolved solids and electrical conductance from some wells are significantly high which indicates the serious sea-water intrusionshave occurred. Ko-Hu, Tai-shi and Mai-Law are the worst.The water qualities of deeper aquifer with depth exceed 200 metersshow no sea-water intrusion. A few wells' water samples in Ko-Huhave higher chloride concentration and electrical conductance. It maybe caused by the water from contaminated upper aquifer infiltratesinto lower aquifer. To prevent ground water further beingdeteriorated and reduced the land subsidence, it suggests that the useof water for offshore Industrial Park should not be withdrawn fromlocal ground water aquifer. Long term monitoring of ground waterlevel and quality should be continued to achieve the goal of groundwater resources protection. |
