这一核心将为研究项目、核心、 通过每月研讨会、我们的网站和会议，政府机构和感兴趣的各方。一个 拟议的区域技术委员会活动的中心主题是更直接地参与选定的当前优先事项 负责尽量减少人类接触砷(As)和锰(Mn)的政府机构 通过主要来自地下水的家庭供水。将鼓励每个公共机构 识别和共享相关数据持有量。我们将把这些多源数据集成到一个可访问的 地理信息系统(GIS)和制作地图，以加强监测和监管决策 制作。数据集成将帮助缺乏地理信息系统能力和许可的机构和其他利益相关者 其他人则是为了扩大他们的能力。涉及的公共机构分布在四个州(新泽西州、纽约州、密苏里州) 包括县以及联邦和州的工作人员。我们的方法将是整合现有的 纽瓦克盆地及其邻近地区的地球物理、地球化学、水文和社会人口数据 新泽西州北部和南部地区评估污染源(自然和人为)和人类接触 地下水中As和Mn的含量升高。这些努力将包括与政府项目的实地合作 在罗克兰县和哈德逊河谷的其他六个县。环境同位素(氚-3He)将 通过测量得出与砷和锰浓度相关的地下水补给历史。垃圾填埋场作为 将通过现场和实验室联合评估地下水砷和锰含量升高的潜在来源。 铁(Fe)浮体沉淀物的测量，表明它们在缺氧至缺氧地下水中的流动。 垃圾填埋场附近铁浮体化学的初步测量表明，在垃圾填埋场附近经常出现高水平的砷 包括大量使用私人水井的新住宅的地区。作为对潜力的调查的一部分 饮用水AS升高对儿童认知功能的影响，我们的两个研究项目将 涉及新英格兰两个州的大量地下水化学测量。我们将整合 将新数据转换为与NH和ME公共机构使用的格式兼容的GIS格式，以帮助 评估地下水中砷和锰的暴露模式。关于暴露可能性和治疗的信息 备选方案将主要通过政府机构的沟通渠道与公众分享。

This core will provide the framework for sustained communication among research projects, cores, governmental agencies, and interested parties through monthly seminars, our website, and meetings. A central theme of the proposed RTC activities is more direct involvement with ongoing priorities of selected governmental agencies responsible for minimizing human exposure to arsenic (As) and manganese (Mn) through domestic water supplies derived primarily from groundwater. Each public agency will be encouraged to identify and share relevant data holdings. We will integrate these multi-source data into an accessible Geographic Information System (GIS) and produce maps to enhance monitoring and regulatory decision making. The data integration will assist agencies and other stakeholders lacking GIS capacity and permit others to expand their capabilities. The public agencies involved are located in four states (NJ, NY, NH, ME) and include county as well as federal and state personnel. Our approach will be to integrate existing geophysical, geochemical, hydrological, and socio-demographic data for the Newark basin and adjacent areas of northern NJ and southern NY to assess sources (natural and anthropogenic) and human exposure to elevated groundwater As and Mn. These efforts will include field collaboration with government programs in Rockland County and six other counties in the Hudson valley. Environmental isotopes (tritium-3He) will be measured to derive groundwater recharge histories relevant to As and Mn concentrations. Landfills as a potential source for elevated groundwater As and Mn will be evaluated through joint field and laboratory measurements of iron (Fe) floe deposits, indicative of their mobilization in suboxic to anoxic groundwaters. Preliminary measurements of Fe floe chemistry adjacent to landfills indicate frequent high levels of As in areas that include large numbers of new homes using private wells. As part of an investigation of potential impacts of elevated drinking water As on cognitive function in children, two of our research projects will involve numerous measurements of groundwater chemistry in two New England states. We will integrate the new data into GIS formats compatible with those employed by public agencies in NH and ME to help evaluate patterns of exposure to As and Mn in groundwater. Information on exposure potential and treatment options will be shared with the public primarily through governmental agency communication channels.
