Access to clean and safe drinking water is critical to public health and economic prosperity. About 70% of U.S. drinking water comes from surface waters, including the tidal fresh regions of estuaries. Drought, sea level rise, watershed and port & harbor engineering, and changes in land-use are increasingly threatening such water supplies in coastal regions due to increasing risk of salinization. The risk extends to water extraction from the coastal zones for thermoelectric power, irrigation, and industrial production. This project will bring together an interdisciplinary team of researchers and stakeholders to assess the risks of salt contamination of water supplies in tidal rivers, synthesize the current understanding and identify knowledge gaps. A better understanding of climatic and other anthropogenic effects on the water supplies will be valuable for bolstering the resilience of water infrastructure and protecting public health.A series of virtual web panels and an in-person workshop will be organized to assess the science on this emerging topic. Case studies of saltwater intrusion and freshwater salinization in tidal rivers in the US and around the world will be discussed and synthesized. The workshop will bring together national and international communities of diverse researchers working on the interdisciplinary aspects of salt contamination of water supplies in tidal rivers, involving senior and early-career scientists, postdoctoral fellows and graduate students. The workshop will include outreach activities through engagement with stakeholders involved in water management, conservation, drinking water treatment operations, and will include participants from the agricultural, industrial, municipal and power generation sectors that rely on access to freshwater sources. The overall goals are twofold: (1) publish a systematic review paper to synthesize current understanding of this interdisciplinary topic and identify major knowledge gaps; (2) produce a forward-looking workshop report to create a research vision and guide future research activities on salt contamination of water supplies in coastal zones.This award is co-funded by the Hydrologic Sciences and Physical Oceanography programs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

获得清洁和安全的饮用水对公共卫生和经济繁荣至关重要。美国大约70%的饮用水来自地表沃茨，包括河口的潮汐淡水区。干旱、海平面上升、流域和港口工程以及土地使用的变化，由于盐碱化的风险越来越大，对沿海地区的水供应构成越来越大的威胁。风险延伸到从沿海地区取水用于热电、灌溉和工业生产。该项目将汇集一个由研究人员和利益攸关方组成的跨学科团队，评估潮汐河流供水盐污染的风险，综合目前的理解并确定知识差距。更好地了解气候和其他人为因素对水供应的影响对于加强水基础设施的恢复能力和保护公众健康将是非常有价值的。将组织一系列虚拟网络小组和一个面对面的研讨会来评估这一新兴主题的科学。本课程将讨论及综合美国及世界各地潮汐河流的盐水入侵及淡水盐化的个案研究。该讲习班将汇集国家和国际上从事潮汐河流供水盐污染跨学科研究的不同研究人员，其中包括资深和早期职业科学家，博士后研究员和研究生。讲习班将包括通过与参与水管理、保护、饮用水处理业务的利益攸关方接触开展外联活动，并将包括来自依赖淡水资源的农业、工业、市政和发电部门的与会者。总体目标有两个方面：（1）发表一份系统性审查文件，综合目前对这一跨学科专题的理解，并确定主要的知识差距;（2）编写一份前瞻性的研讨会报告，以创建研究愿景，并指导未来关于沿海地区供水盐污染的研究活动。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准。
