中文摘要 | 嘉義縣沿海地區,因缺乏地面水源,除了抽取地下水以補灌溉用水之不足外,又 由於養殖、畜牧及工業等用水等競相抽用,致已引起不同程度之地層下陷,海水入侵及水質 污染,此乃不爭之事實。然對距沿海較近之內陸區域而言,其地下水質是否亦已遭受不同程 度之污染,實值加以分析研究,以為水資源規劃管理之參考。本文之研究目的旨在瞭解嘉義 縣義竹地區地下水質之變化,故於 1992 年實地調查該區境內壹仟多口水井,並選取具代表 性且資料完整之樣井 131 口,檢驗其水溫、酸鹼度、電導度、總固體量, 懸浮固體量、總 二氧化碳、硫酸鹽、氯鹽、鈣、鎂、鈉等項,以為地下水質之管理與監測之參考,經分析結 果得知:1 •本區之 pH 值皆在 6 ∼ 9 之間,符合灌溉用水標準。然氯鹽、硫酸盬、電導 度、鈉吸著率等值皆偏高,顯示該區已有不同程度之鹽化現象。2 •依灌溉水品質等級而言 ,以竿子寮、北港子、新店、埤子頭等段之污染最為嚴重,故該段地下水體已不適宜灌溉。 3 •由海水污染程度分析以竿子寮段所受污染最為嚴重,此乃地下水嚴重超抽所致,故應立 刻停止開發地下水,並加強水權管理。 |
英文摘要 | At Yi-Jui District, because of the shortage of surface water resource, groundwater becomes the major water resource for agricultural, husbandary, industrial and commerical uses. The occurrence of land subsidence, seawater intrusion and the deterioration of groundwater quality become more and more serious due to over pumping. In this report, 131 wells are the representative and basic background information were selected from more than one thousand wells selected aroung the Yi-Jui district. From the examined results, including temperature, pH、 Cl-、 SO �� -、 Ca �� +、 Mg �� + Na+ … etc. The following conclusions may be drawn: 1. The examined results of Cl-、 SO �� -, EC and SAR, except the pH values, are higher than normal standard. Therefore this district has been suffering from different degree of salinity. 2. Based on the classification of irrigation water quality, the worst areas affected are kcanjuilwa, Peykenju Shindan and Peyjutou. The results of ground water analysis at these area are not suitable for irrigation. 3. The results of seawater pollution analysis show that kcanjuilwa is the most polluted area. The predominent cause is due to overpuming. Therefore, we suggest that preventing of mining groundwater and caring out water rights must be the primary concern. |
