描述：该项目将使用数学模型来研究 控制有毒物质运输的物理和化学因素 阿伯乔纳河流域的金属。重点将放在休闲上 分水岭北部金属来源与 从G井和H井抽出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G井和H井抽水中金属含量 1970年的S和1980年初的S。这些预测将有助于马萨诸塞州 麻省理工学院毒物学家评估 金属污染和有充分记录的儿童白血病聚集症。 该项目的具体目标是：1)开发小型模型 工业园区的地下水流动和相关金属运移 G井和H井；2)建立了水流和输运模型，该模型 描述溶解的和悬浮的金属从 工业综合体通过阿伯乔纳河到G井和H井；以及3)使用 用于检验现场观测所提出的传输假说的模型和 估计抽水中历史上的金属浓度 虽然重点放在阿伯乔纳分水岭上，但 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的任何地区的运输 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.
