CHARACTERIZING GROUNDWATER CONTAMINATION AT A HETEROGENOUS FIELD SITE

描述：本项目将使用数学模型来研究 控制有毒物质迁移的物理和化学因素 在阿伯乔纳河流域的金属。重点将放在休闲 流域北方金属来源之间的联系， 从威尔斯G和H井抽取的饮用水可能受到污染， 位于分水岭中心附近。模型将用于 预测从威尔斯G和H井泵出的水中的金属浓度， 70年代和80年代初。这些预测将帮助马萨诸塞州 技术研究所毒理学家评估之间的联系 金属污染和儿童白血病集群 该项目的具体目标是：（1）开发小规模的 地下水流和相关金属在工业区的迁移， 威尔斯G井和H井; 2）建立一个水流和运输模型， 描述了溶解和悬浮金属的运动， Industriplex至威尔斯G井和H井，通过Aberjona河;以及3）使用 实地观察所提出的运输假设的检验模型， 估计历史上饮用水中的金属浓度， 威尔斯G和H虽然重点是阿伯乔纳流域， 最终目标是了解控制金属的过程 在环境污染可能影响人类健康的任何地区进行运输 健康

Description: This project will use mathematical models to investigate the physical and chemical factors which control the transport of toxic metals in the Aberjona River watershed. Emphasis will be on casual links between metals sources in the northern part of the watershed and the possible contamination of drinking water pumped from Wells G and H, located near the center of the watershed. Models will be used to predict metals concentrations in water pumped from Wells G and H during the 1970's and early 1980's. These predictions will help Massachusetts Institute of Technology toxicologists evaluate connections between metals contamination and a well-documented childhood leukemia cluster. The specific aims of the project are: 1) develop small-scale models of groundwater flow and associated metals transport at the Industriplex and Wells G and H sites; 2) develop a stream flow and transport model which describes the movement of dissolved and suspended metals from Industriplex to Wells G and H via the Aberjona River; and 3) use the models to test transport hypothesis suggested by field observations and to estimate historic metals concentrations in drinking water pumped at Wells G and H. Although the focus is on the Aberjona watershed, the ultimate goal is to understand the processes that control metals transport in any area where environmental contamination can effect human health.
