Collaborative Research: RAPID: Assessment of Water Quality in Puerto Rico after Hurricane Maria

PI：费尔南多·L·罗萨里奥-组织合作研究：快速：飓风玛丽亚于2017年9月20日登陆波多黎各后，波多黎各水质评估。这场飓风的后遗症继续伤害着许多波多黎各公民，因为它对该岛的基础设施造成了毁灭性的影响，而且重建工作仍在继续进行。鉴于飓风玛丽亚对水基础设施造成的影响，现在是一个独特和重要的机会，可以对与恢复饮用水服务有关的水质问题进行详细评估。有两个主要的担忧。第一个关切是与由波多黎各渡槽和下水道管理局管理的集中式水处理和分配有关的水质问题。在这些系统中，与启动和恢复正常有关的处理问题可能会导致不可预测的水质，表现为潜在病原体、消毒副产品和其他有机污染物水平较高。此外，配水系统的完整性可能会受到水质变化的影响，因为水质变化会调动金属和潜在的渗漏点。这些情况导致人群暴露于潜在有毒或病原体的风险增加，有可能广泛影响公共卫生。还有一个问题是与PRASA无关的较小的社区系统。在这里，地表水的污染，加上基础设施的崩溃，可能会产生破坏性的影响。这项快速提案的主要目标是对波多黎各几个饮用水系统的水质进行系统调查和评价，重点是化学和微生物成分。该项目的主要成果将是对飓风玛丽亚的近期后果进行使用点水质回顾，包括对化学和微生物之间的潜在关系进行分析，以确定受影响的水处理和分配系统。拟议的研究将提供信息，说明在严重破坏的热带环境中化学和微生物制剂之间的潜在关系。鉴于所采集水样的范围，该项目将帮助工程界更好地了解与公众健康相关的水暴露情况。

PI: Fernando L. Rosario-OrtizCollaborative Research: RAPID: Assessment of Water Quality in Puerto Rico After Hurricane MariaHurricane Maria made landfall in Puerto Rico (PR) on September 20th, 2017. This hurricane's legacy continues to harm many Puerto Rican citizens because of the devastating impact to this Island's infrastructure and the continuing struggle to rebuild it. Given the impacts that Hurricane Maria had on the water infrastructure, a unique and important opportunity exists to conduct a detailed evaluation of water quality issues related to the restoration of potable water service. There are two main concerns. The first concern is regarding the water quality associated with centralized water treatment and distribution that is governed by the Puerto Rico Aqueduct and Sewer Authority (PRASA). In these systems, treatment issues associated with start-up and return to normalcy will likely cause unpredictable water quality that manifest itself in higher levels of potential pathogens, disinfection byproducts and other organic contaminants through water distribution. In addition, the integrity of the distribution system could be compromised by changes in water quality that mobilize metals and potential leakage points. These conditions result in an increased population exposure risk to potentially toxic or pathogenic agents, with potential for wide spread public health impacts. There is also the concern with the smaller community systems, that are not associated with PRASA. Here, contamination of surface water, combined with the collapse of the infrastructure, could have damaging effects. The main objective of this RAPID proposal is to conduct a systematic survey and evaluation of water quality in several Puerto Rican potable water systems, focusing on both chemical and microbiological components. The main outcome from this project will be a point-of-use water quality retrospective of the near-term aftermath of Hurricane Maria, including an analysis of potential relationships between the chemistry and microbiology compromised water treatment and distribution systems. The proposed research will provide information on potential relationships chemical and microbiological agents in a seriously compromised tropical setting. Given the scope of water samples collected, this project will the engineering community to better understand water related exposures relevant to public health.
