Abstract This work presents analysis of breakthrough curves collected from monitoring wells located around an impoundment that leaked produced water in fractured bedrock. The analysis demonstrated that fractured bedrock flow could be highly heterogeneous, with produced water impacting some monitoring well, but not others located within the same distance as impacted wells, and within the same general alignment from the leaking impoundment. Breakthrough curves that were collected before and after the impoundment leak event contained information that was used to reconstruct events that led to the leaking of the impoundment. The breakthrough curve analysis methods presented in this work could be used in similar situations where groundwater flow is dominated by unidirectional fracture porosity.

对断裂基岩中的突破曲线进行法医分析，以重建过去的污染物释放事件——案例研究

摘要 这项工作对从位于裂隙基岩中泄漏采出水的蓄水池周围的监测井收集到的突破曲线进行了分析。分析表明，裂隙基岩流可能是高度不均匀的，产出水会影响一些监测井，但不会影响与受影响井位于相同距离内的其他水井，并且与泄漏的蓄水池处于相同的总体路线内。在蓄水泄漏事件之前和之后收集的突破曲线包含用于重建导致蓄水泄漏事件的信息。这项工作中提出的穿透曲线分析方法可用于地下水流以单向裂缝孔隙度为主的类似情况。
