Abstract

Two dense nonaqueous phase liquid (DNAPL) tracer tests were carried out in a shallow aquifer north of Fort Worth, TX. i-Propanol was used as the nonpartitioning tracer: n-hexanol and n-octanol were the partitioning tracers. Field data, mathematical modeling, the results of column tests, and field tracer tests with NaCl were used in designing the DNAPL tracer tests. The results indicated the presence of DNAPL at both sites tested; semi-quantitative estimates of the amounts of DNAPL present were obtained by mathematical modeling. Interpretation was complicated by heterogeneity of the aquifer and mass transport effects.

摘要

在德克萨斯州沃思堡以北的浅层含水层中进行了两次致密非水相液体（DNAPL）示踪剂测试。异丙醇用作非分配示踪剂：正己醇和正辛醇用作分配示踪剂。在设计DNAPL示踪剂测试时，使用了现场数据、数学模型、柱测试结果以及用氯化钠进行的现场示踪剂测试。结果表明，在两个测试地点均存在DNAPL；通过数学模型获得了DNAPL存在量的半定量估计。含水层的非均质性和传质效应使解释变得复杂。
