在亚利桑那州皮马县圣克鲁斯河沿岸的地面运输和偶然补给过程中，对废水中雌激素活性的命运进行了检查。根据硼同位素的测量，确定了当代样本集中靠近河流的地表水和地下水井中再生水的部分贡献。图森污水排放点以下 25 英里长的河流中，雌激素活性下降了 -60%。在从圣克鲁斯河附近的监测井获得的地下水样本中，溶解有机碳 (p= 0.0003) 和雌激素活性 (p= 3 × 10−6) 与废水含量高度相关。结果表明，邻近地下水质量对圣克鲁斯河床再生水的附带补给很敏感。在一些地点，在河道中的污水渗滤到取水点的过程中，雌激素活性几乎没有明显减弱。
The fate of estrogenic activity in waste water effluent was examined during surface transport and incidental recharge along the Santa Cruz River in Pima County, Arizona. Based on measurement of boron isotopes, the fractional contribution of reclaimed water in surface waters and ground water wells proximate to the river was determined for a contemporary sample set. Estrogenic activity decreased by −60% over the 25 mi length of the river below effluent discharge points in Tucson. In ground water samples obtained from monitoring wells that are proximate to the Santa Cruz River, both dissolved organic carbon (p= 0.0003) and estrogenic activity (p= 3 × 10−6) were highly correlated to fractional waste water content. Results indicate that proximate ground water quality is sensitive to incidental recharge of reclaimed water in the Santa Cruz River bed. In a few locations, little attenuation of estrogenic activity was apparent during percolation of effluent in the river channel to well withdrawal points.
