1654958MitchDisinfection of drinking water is one of the major public health achievements of the last century; however, but the chemical byproducts (disinfection by-products) that form represent one of the most widespread exposures to potentially harmful chemicals. Optimizing the balance between the acute risk posed by pathogens and the chronic risk posed by disinfection by-products is becoming more challenging as utilities experiment with new disinfectant combinations and exploit impaired waters. The 2017 Gordon Research Conference on Drinking Water Disinfection By-Products (DBPs) will present cutting-edge research to address this challenge from the fields of engineering, chemistry, toxicology, epidemiology and regulatory policy. The 2017 meeting, entitled Disinfection 2100: Linking Engineering, Chemistry, Toxicology, and Epidemiology to Reduce Exposure to Toxicity Drivers While Curtailing Pathogens, will take place from July 30-August 4, 2017 at Mt. Holyoke College in South Hadley, MA.The conference has two main goals. The first goal is to broaden the scope beyond DBP formation within conventional drinking water plants. The first two sessions will directly address the balance between the acute risk associated with pathogens and the chronic risk linked to DBPs. The first session will evaluate disinfectant reactions with pathogens, recognizing that the biomolecular transformations responsible for pathogen kill are DBPs. The second session will cover tradeoffs between microbial growth and DBPs within distribution systems, the least evaluated sector of drinking water systems. The sixth section will focus on DBPs in wastewater recycling, particularly which DBPs contribute most to toxicity and how to control them. The conference will also include new arenas for DBPs, including the formation of DBPs during food processing. The second goal is to move towards a solution to the DBP problem. A major strength of this conference is that it brings together engineers, chemists, toxicologists, epidemiologists and regulators, the key players for addressing this problem. Previous conferences have concluded that there is no feasible way to control pathogens without producing DBPs, so the challenge is to achieve the best balance that minimizes exposure to the DBPs driving risk. Sessions will link chemistry and toxicology to identify these toxicity drivers. Session 8 will feature discussions among chemists, exposure experts and epidemiologists about how the ideal epidemiology study should be designed to provide the evidence to link exposure to human health risks. Session 9 will conclude with presentations and a discussion regarding how to design water treatment systems that minimize toxicity drivers, including a presentation from a Dutch utility on how to avoid the use of disinfectants in drinking water distribution systems. With US utilities currently modifying their disinfection schemes and exploiting impaired water supplies, it is important for experts in engineering, chemistry, toxicology, epidemiology and regulatory policy to discuss the risk balance between pathogens and DBPs resulting from these new practices. The 4.5-day Gordon Research Conference format, with lengthy discussion periods and ample provision for informal discussions and social interactions, is particularly suited to promoting the needed multidisciplinary approach. The Conference will be preceded by 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 career mentoring panel by established academic, government and industrial scientists. Gordon Conferences are often considered the pre-eminent conferences in their fields. By highlighting emerging researchers as presenters in the GRC and encouraging the development of young scientists through the GRS, this conference will help lay a solid foundation for multidisciplinary research for the next generation of scientists.

Holyoke College in South Hadley, MA.The conference has two main goals.第一个目标是扩大范围，超越传统饮用水厂内 DBP 的形成。前两场会议将直接讨论与病原体相关的急性风险和与 DBP 相关的慢性风险之间的平衡。 The first session will evaluate disinfectant reactions with pathogens, recognizing that the biomolecular transformations responsible for pathogen kill are DBPs. The second session will cover tradeoffs between microbial growth and DBPs within distribution systems, the least evaluated sector of drinking water systems.第六部分将重点讨论废水回收中的 DBP，特别是哪些 DBP 对毒性影响最大以及如何控制它们。会议还将包括 DBP 的新领域，包括食品加工过程中 DBP 的形成。第二个目标是解决 DBP 问题。 A major strength of this conference is that it brings together engineers, chemists, toxicologists, epidemiologists and regulators, the key players for addressing this problem.之前的会议得出的结论是，没有可行的方法可以在不产生 DBP 的情况下控制病原体，因此挑战是实现最佳平衡，最大限度地减少暴露于 DBP 带来的风险。会议将化学和毒理学联系起来，以确定这些毒性驱动因素。第 8 场会议将由化学家、暴露专家和流行病学家讨论如何设计理想的流行病学研究，以提供将暴露与人类健康风险联系起来的证据。 Session 9 will conclude with presentations and a discussion regarding how to design water treatment systems that minimize toxicity drivers, including a presentation from a Dutch utility on how to avoid the use of disinfectants in drinking water distribution systems. With US utilities currently modifying their disinfection schemes and exploiting impaired water supplies, it is important for experts in engineering, chemistry, toxicology, epidemiology and regulatory policy to discuss the risk balance between pathogens and DBPs resulting from these new practices.为期 4.5 天的戈登研究会议形式，具有漫长的讨论时间和充足的非正式讨论和社交互动空间，特别适合促进所需的多学科方法。会议之前将举行为期 1.5 天的戈登研究研讨会 (GRS)，由早期职业科学家组织。 The GRS will feature presentations by graduate students and postdoctoral fellows, and a career mentoring panel by established academic, government and industrial scientists.戈登会议通常被认为是各自领域的杰出会议。 By highlighting emerging researchers as presenters in the GRC and encouraging the development of young scientists through the GRS, this conference will help lay a solid foundation for multidisciplinary research for the next generation of scientists.
