The 2019 Gordon Research Conference entitled "Water Disinfection, By-Products, and Health: Finding Solutions to Emerging Issues Related to Disinfection Byproducts by Advanced Multidisciplinary Approaches" will be held at Mount Holyoke College in South Hadley, MA on July 27-August 2, 2019. The Conference will succeed a 1.5-day Gordon Research Seminar (GRS), organized by early career scientists. The GRS will feature presentations by graduate students and postdoctoral fellows, and a mentoring panel for young professionals. At the 2019 GRC/GRS, about 160 participants including academics, regulators, graduate students, postdoctoral fellows, industrial scientists, and water professionals from around world will present cutting-edge research to address challenges in providing sustainable safe drinking water. Disinfection of drinking water is one of the major public health achievements to prevent waterborne-diseases in the last century. Multiple global issues, including contaminated and diminishing water supplies, demand innovative technologies for effective treatment of new and existing water sources to provide safe drinking water to consumers. Different source waters (e.g., those impacted by domestic or industrial wastewater) require different disinfection strategies and therefore generate different types and amounts of disinfection byproducts (DBPs). When choosing disinfection treatment processes, many water utilities prioritize the reduction of specific DBPs to comply with regulatory guidelines. However, a treatment process that yields low levels of the regulated DBPs may produce higher concentrations of other more toxic DBPs. This raises new challenges in balancing microbial and chemical risks. Epidemiological studies have shown potential associations of DBP exposure with increased risk of bladder and colorectal cancers as well as adverse developmental effects. However, the DBPs responsible for the observed health effects remain unclear. Although hundreds of DBPs have been identified, the majority are still unknown and unclassified. These knowledge gaps present tremendous challenges in choosing treatment strategies, monitoring water quality, assessing health risks, and improving regulatory guidelines. The objectives of the 2019 GRC/GRS are (1) to fill the knowledge gap in identifying unknown DBPs of health relevance by integrating advanced analytical and toxicological testing technologies; (2) to get a better understanding of the mechanisms of DBP formation and transformation to engineer innovative disinfection schemes for better control of DBPs; (3) to discuss recent advances in exposure and epidemiological assessment for improving future guidelines. The cutting-edge research in the fields of engineering, chemistry, toxicology, epidemiology and regulatory policy will contribute to the central goal of protection of human health.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.

2019年戈登研究会议的标题为“水消毒，副产品和健康：寻找与消毒的问题有关的解决方案与先进的多学科方法有关的新兴问题”将于2019年7月27日至8月2日在马萨诸塞州南哈德利的霍利奥克山学院举行。 GRS将展示研究生和博士后研究员的演讲，以及针对年轻专业人士的指导小组。在2019年GRC/GRS上，包括学者，监管机构，研究生，博士后研究员，工业科学家和来自世界各地的水上专业人士在内的大约160名参与者将提出尖端的研究，以应对提供可持续安全饮用水的挑战。 饮用水的消毒是预防上世纪水上疾病的主要公共卫生成就之一。多个全球问题，包括受污染和减少的水供应，需要创新技术，以有效治疗新的和现有的水源，以向消费者提供安全的饮用水。不同的来源水域（例如，受家庭或工业废水影响的水）需要不同的消毒策略，因此产生了不同类型和数量的消毒副产品（DBP）。在选择消毒处理过程时，许多水公用事业优先级减少特定DBP，以符合监管指南。但是，产生较低水平的受调节DBP的治疗过程可能会产生更高浓度的其他毒性DBP。这在平衡微生物和化学风险方面提出了新的挑战。流行病学研究表明，DBP暴露与膀胱和结直肠癌的风险增加以及不良发育效果的潜在关联。但是，负责观察到的健康效应的DBP尚不清楚。尽管已经确定了数百个DBP，但大多数仍然未知且未分类。这些知识差距在选择治疗策略，监测水质，评估健康风险以及改善监管指南方面面临着巨大的挑战。 2019 GRC/GRS的目标是（1）通过整合先进的分析和毒理学测试技术，以填补识别未知健康相关DBP的知识差距； （2）更好地了解DBP形成的机制和转化为工程师创新的消毒计划，以更好地控制DBP； （3）讨论有关改善未来指南的暴露和流行病学评估的最新进展。在工程，化学，毒理学，流行病学和监管政策领域的尖端研究将有助于保护人类健康的中心目标。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准来评估通过评估来支持的。
