大峡谷（美国亚利桑那州）的“水走廊”包括跨洋管道，该管道将水从咆哮泉（北缘）输送到大峡谷村（南缘），以供应公园每年500 - 600万游客。自20世纪60年代以来，北缘水一直在南缘水回收厂（WRP）回收。本报告描述了一种假设，即返回的管道水沿着Bright Angel断层渗透并与地下水混合。地球化学示踪剂（主要离子，稳定同位素）被用来定义端元和开发南缘地下水混合模型。结果发现，哈瓦苏派花园泉水，在南缘以下沿着明亮的天使断层（WRP以下约1公里）排放，是北缘水的约40%。其他位于边缘以下的南缘泉水也有10-60%的人为北缘贡献。同样，图萨扬镇和皮尼恩平原铀矿的科科尼诺高原地下水威尔斯可能含有北缘百分之几十的水。与这一假设相一致的是，在WRP的排放物中以及在边缘以下的Havasupai花园泉和Pipe Creek泉中发现了微量的药品和个人护理产品。这项研究解释了水化学变化的南缘泉水和地下水，主要是由于人为的地下水混合，其次是由于当地补给的变化，如其他人提出的。这一假设表明，铀矿开采、当地地下水抽取、管道和WRP基础设施的管理都是相互关联的南缘地下水系统的一部分。
The “water corridor” of Grand Canyon (Arizona, USA) includes the Transcanyon Pipeline, which conveys water from Roaring Springs (North Rim) to Grand Canyon Village (South Rim) to supply the park’s 5–6 million annual visitors. The North Rim water has been reclaimed at the South Rim Water Reclamation Plant (WRP) since the 1960s. This report describes a hypothesis in which the returned pipeline water infiltrates along the Bright Angel Fault and intermingles with groundwater. Geochemical tracers (major ions, stable isotopes) are used to define end members and develop mixing models for South Rim groundwater. It was found that Havasupai Gardens Spring water, discharging below the South Rim along the Bright Angel Fault (~1 km below the WRP), is ~40% North Rim water. Other South Rim springs below the rim also have 10–60% anthropogenic North Rim contribution. Similarly, Coconino Plateau groundwater wells in the town of Tusayan and the Pinyon Plain uranium mine may contain tens of percent of North Rim water. Compatible with this hypothesis, pharmaceutical and personal-care products present in discharge from the WRP, and also in Havasupai Gardens Spring and Pipe Creek Spring below the rim, were found in trace amounts. This study explains the hydrochemical variability of South Rim springs and groundwater as primarily due to anthropogenic groundwater mixing and secondarily due to variations in local recharge, as proposed by others. The hypothesis suggests that uranium mining, local groundwater pumping, and management of the pipeline and WRP infrastructure are all part of an interconnected South Rim groundwater system.
