The physicochemical characteristics and concentrations of heavy metals from 14 groundwater and two wastewater samples were measured to evaluate the effects of various natural and anthropogenic pollutions on the Boroujen aquifer in southwestern Iran. Comparing the location of sampling stations and wastewater treatment plant of the industrial zone with the geochemical maps showed that there are no anomalies of the studied elements in the aquifer area. Therefore, it is included that anthropogenic pollutions such as industrial wastewater are a major factor in increasing the concentrations of the studied elements. Except the hydrogeochemical parameters, the clustering of heavy metals and other studied elements showed that the concentrations of these parameters are mainly affected by two type of wastewater. Sampling stations are classified into two clusters, which were assigned based on their location in the aquifer. Environmental indices showed that many samples, especially those located downstream of the industrial zone along the direction of the hydraulic gradient of the aquifer, are contaminated. The highest pollution was related to Zn, P, Cu, and Ba. Meanwhile, the most polluted samples were related to stations 5 and 9 in the downstream of the industrial zone and stations 8 and 11 northeast of the aquifer and upstream of the industrial zone, respectively. Comparison of the concentrations of Zn, P, and Cu in wastewater and aquifer samples revealed the penetration of some of these elements into the aquifer, their movement in the direction of hydraulic gradient, and an increase in their concentrations in downstream stations.

工业废水对伊朗西南部Boroujen含水层地下水质量的影响

测量了14个地下水和两个废水样品中的重金属的理化特性和浓度,以评估各种自然和人为污染对伊朗西南部Boroujen含水层的影响。将工业区的采样站和废水处理厂的位置与地球化学图进行比较表明,在含水层区域中没有研究元素的异常。因此,包括人为污染(例如工业废水)是增加所研究元素浓度的主要因素。除水文地球化学参数外,重金属和其他元素的聚集表明,这些参数的浓度主要受两种类型的废水的影响。采样站分为两个簇,根据它们在含水层中的位置进行分配。环境指数表明,许多样品,特别是沿含水层水力梯度方向位于工业区下游的样品,均受到污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。根据其在含水层中的位置进行分配。环境指数表明,许多样品,特别是沿含水层水力梯度方向位于工业区下游的样品,均受到污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。根据其在含水层中的位置进行分配。环境指数表明,许多样品,特别是沿含水层水力梯度方向位于工业区下游的样品,均受到污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。环境指数表明,许多样品,特别是沿含水层水力梯度方向位于工业区下游的样品,均受到污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。环境指数表明,许多样品,特别是沿含水层水力梯度方向位于工业区下游的样品,均受到污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。被污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。被污染。最高污染与锌,磷,铜和钡有关。同时,污染最严重的样品分别与工业区下游的站5和9,含水层东北和工业区上游的站8和11有关。比较废水和含水层样品中Zn,P和Cu的浓度,可以发现其中一些元素渗透到含水层中,它们在水力梯度方向上的运动以及下游站中其浓度的增加。
