The objective of this study was to evaluate the ability of funnel-and-gate structures augmented with passive wells containing filter cartridges to capture contaminated groundwater in hypothetical, homogeneous and heterogeneous, unconfined aquifers. Perpendicular to groundwater flow, linear structures were 15 m wide, 1 m thick, and keyed into the base of the aquifer. Gates occupied 4 m of the total width of each simulated structure; one gate was 5 m from a contaminant plume's leading tip, while others occupied cross-gradient margins of the plume. Results suggest a modest reduction in remediation timeframes, up to 425 d per well added in these simulations; however, incremental benefits are highly variable and case specific.
本研究的目的是评估带有被动井的漏斗和门结构的能力，这些被动井中装有过滤筒，以捕获假想的均质和非均质、无压含水层中的污染地下水。垂直于地下水流动方向，线性结构宽 15 米，厚 1 米，并与含水层的底部相接。每个模拟结构的总宽度中有 4 米是门的位置；一个门距离污染物羽流的前缘 5 米，而其他门位于羽流的横梯度边缘。结果表明，修复时间框架略有缩短，每个井增加了 425 天；然而，增量效益高度可变且具体情况具体分析。
