Safe and affordable supply of drinking water (DW) in the EU under the pressure of climate change is a key priority. Despite long-term experience with the reliable operation of disinfected and non-disinfected drinking water supply systems (DWSS), several challenges around microbial stability, the (future) need for disinfection and the consequences of disinfection by-products (DBPs) formation for human health remain open, directly deriving from climate change impacts such as increasing water temperature and higher levels of natural organic matter (NOM). Safe CREW aims to support the novel EU DW Directive by generating advanced knowledge and developing tools and guidelines for disinfected and non-disinfected DWSS and addresses improved comprehensive water quality characterization, novel treatment solutions to actively respond to identified threats, and the management of distribution networks to avoid water quality deterioration up to consumers. Novel data sets on the occurrence and concentration of so far unknown DBPs will be created, and commercial actors stimulated to further develop tools for DBP quantification and mitigation. Transferable tools will be provided to end-users (water utilities, national/EU regulators, researchers, SMEs), including: (I) reliable methods to evaluate microbial stability, characterise NOM, detect DBPs and account for DBP human health toxicity, (II) protocols to select proper materials in contact with disinfected water, (III) monitoring and modelling tools, also exploiting machine learning, for real-time optimisation of DWSS management, and (IV) an integrated risk assessment framework to guide future interventions which ensure that both disinfected and non-disinfected DWSS can continue providing safe DW in the face of climate change. Safe CREW will increase the preparedness of the EU water sector to challenges arising from climate change and will support the EU’s leading position in science-based policy making for DW consumer protection.

在气候变化的压力下，在欧盟提供安全和负担得起的饮用水(DW)是一个关键的优先事项。尽管在消毒和非消毒饮用水供应系统(DWSS)的可靠运行方面有着长期的经验，但围绕微生物稳定性、(未来)消毒需求以及消毒副产品(DBPs)形成对人类健康的后果的几个挑战仍然悬而未决，直接源于气候变化的影响，如水温上升和天然有机物(NOM)水平升高。Safe Crew旨在通过产生先进的知识和开发消毒和非消毒DWSS的工具和指南来支持新的欧盟DW指令，并解决改进的综合水质表征、积极应对已识别的威胁的新型处理解决方案以及防止用户水质恶化的配电网管理。将建立关于迄今未知的二氯苯酚的发生和浓度的新的数据集，并鼓励商业行为者进一步开发DBP的量化和缓解工具。将向最终用户(自来水公司、国家/欧盟监管机构、研究人员、中小企业)提供可转让的工具，包括：(I)评估微生物稳定性的可靠方法，确定NOM，检测DBPs并说明DBP对人类健康的毒性，(Ii)选择与消毒水接触的适当材料的协议，(Iii)监测和建模工具，也利用机器学习，以实时优化DWSS管理，以及(Iv)综合风险评估框架，以指导未来的干预措施，确保已消毒和未消毒的DWSS能够在面对气候变化时继续提供安全的DW。Safe Crew将加强欧盟水务部门应对气候变化带来的挑战的准备，并将支持欧盟在基于科学的DW消费者保护政策制定方面的领先地位。
