A shallow-depth ground water area was investigated to identify the dominant processes governing the distribution of hydrocarbon contaminants and hydrogeochemical parameters. The ground water in the study site has been highly contaminated with petroleum hydrocarbons. A preliminary pump-and-treatment remediation technology was applied for 4 yr at the site. Multivariate analyses were applied to hydrogeochemical data obtained before and after the rainy season. The pump-and-treatment application, indigenous biodegradation, and mixing by precipitation recharge are the major factors or events involved in the distribution of geochemical parameters of the ground water in the study area. Site-specific artificial pavement also played an important role in the evolution of the ground water chemistry. A conventional graphical analysis method (Piper plot) of major ions did not effectively reveal these effects. In this study, we demonstrate the usefulness of multivariate analysis (factor and cluster analyses) using biodegradation indicator parameters, as well as major cations and anions, for the study of the ground water system in the hydrocarbon-contaminated site.
对一个浅埋深度的地下水区域进行了调查,以确定控制碳氢化合物污染物分布和水文地球化学参数的主要过程。研究地点的地下水已受到石油碳氢化合物的高度污染。在该地点应用了初步的抽提处理修复技术4年。对雨季前后获得的水文地球化学数据进行了多变量分析。抽提处理应用、原生生物降解以及降水补给引起的混合作用是研究区域地下水中地球化学参数分布所涉及的主要因素或事件。特定地点的人工路面在地下水化学演变中也起到了重要作用。主要离子的传统图形分析方法(派珀图)未能有效揭示这些影响。在本研究中,我们证明了使用生物降解指示参数以及主要阳离子和阴离子进行多变量分析(因子分析和聚类分析)对于研究受碳氢化合物污染场地的地下水系统的有用性。
