Alternative networks of non-pumped wells filled with reactive media were evaluated for groundwater remediation capability. Wells were screened across the saturated zone of a simulated, unconfined aquifer with a heterogeneous hydraulic conductivity. A numerical mass transport model generated an initial contaminant plume and then simulated its movement through different networks of non-pumped wells. Two cases were investigated: (1) a linear transect of wells downgradient of the plume; and (2) a downgradient linear transect combined with a second linear transect crossing the plume's interior. Several simulations were conducted for each case to determine the smallest number of wells necessary to prevent the plume from traveling offsite. Case 2 required 11% more wells, but reduced cleanup time by 21%.
替代性的、充满反应性介质的无泵井网络被评估用于地下水修复能力。井被安装在一个模拟的、无隔水层的含水层的饱和带中，这些井具有非均质地水力传导率。一个数值质量传输模型生成了一个初始污染物羽流，然后模拟了它通过不同的无泵井网络的移动。研究了两种情况：（1）羽流下游的线性井列；（2）与穿过羽流内部的第二条线性井列组合的下游线性井列。对每种情况进行了多次模拟，以确定防止羽流流出场地所需的最少井数。第二种情况需要多 11%的井，但减少了 21%的清理时间。
