摘要
依据新疆石河子地区2014年23组地下水水样测试数据对该区进行地下水污染评价。采用综合指数法对地下水无机污染进行评价,结果表明,21组地下水水样受到不同程度的无机污染,承压水污染较潜水污染严重,潜水以轻微污染为主,浅层承压水以严重污染为主,深层承压水以中度污染为主。根据检出的微量有机指标进行地下水有机污染评价,结果表明:5组潜水未受到有机物的污染,承压水受到有机物的污染,其中,8组浅层承压水中1,2-二氯乙烷和总六六六的检出率为12.5%,10组深层承压水中甲苯和苯并(a)芘的检出率为10%。该区地下水污染主要受到地质条件、地表水水质和污染源等的影响。
This study evaluated the groundwater pollufion based on the testing data of 23 groundwater samples in Shihezi area of Xinjiang in 2014. The comprehensive index method was used to evaluate the groundwater inorganic pollution. The results showed that 2l groundwater samples were polluted by inorganic ions in different degrees. Confined water pollution was more serious than phreatic water pollution. The phreatic water, shallow confined water and deep confined water pollution degree mainly were slight, serious and moderate, respectively. Also we evaluated the groundwater organic pollution by the detected trace organic index. The results showed that the five phreatic water samples were not contaminated by organic matter, while the confined water samples were contaminated by organic matter. The detection rates of 1,2 -dichloroethane and total BHC were 12.5% for eight shallow confined water samples, the detection rates of Toluene and Benzo（a） pyrene were 10% for ten deep confined water samples. Groundwater pollution was mainly influenced by the geological conditions, surface water quality and pollution sources in Shihezi area.
