forWater: NSERC Network for Forested Drinking Water Source Protection Technologies

饮用水是社会最关键的用水需求之一，提供安全饮用水--安全--是**国家战略优先事项。大多数加拿大人刚刚开始意识到这种基本资源是多么的脆弱，以及**气候变化和高能源成本可能对饮用水安全产生的潜在灾难性影响。**为了减少对公共健康的风险，加拿大卫生部依靠“多障碍方法”来防止或减少**饮用水从源头到自来水的污染。该框架的所有变体都确定了用于风险预防的水源**保护(SWP)和用于风险管理的厂内处理技术。值得注意的是，这一框架中的所有障碍都必须有效，以确保饮用水安全。与气候变化有关的**干扰(野火、飓风、洪水)暴露了多障碍办法目前实施的令人震惊的不足之处。这些干扰正在造成日益多变或恶化的污染源质量，**并挑战厂内处理技术，超出设计和操作响应能力，达到**服务中断的程度。水务行业的共识表明，迫切需要新的水资源利用规划技术来适应气候变化，以确保社区供水系统的安全。在加拿大，有效的水源保护必须侧重于**森林水源流域，因为那里是大多数城市、农村和土著**社区的饮用水来源。健康的森林通常产生高质量的水--全球森林对水的自然储存和**过滤的价值估计为4.1万亿美元。森林管理办法**被建议作为SWP技术，包括为先发制人降低风险**的间伐或规定的焚烧**或减轻潜在灾难性干扰的反应效果。虽然森林管理对**水的影响已经得到了很好的研究，但这些工作几乎没有专门侧重于饮用水的可处理性，**这可能会因地区而异。FORW水网络将提供关于不同森林管理战略对饮用水水源质量和可处理性的影响**的新知识，以评估其作为加拿大主要生态/森林区域的SWP技术的**适宜性。

Drinking water is one of society's most critical water needs and delivery of safe drinking water-security-is a**national strategic priority. Most Canadians are just becoming aware how fragile this essential resource is and**the potentially catastrophic effects climate change and high energy costs can have on drinking water security.**To reduce risks to public health, Health Canada relies on the "multi-barrier approach" to prevent or reduce the**contamination of drinking water from source to tap. All variations of this framework identify source water**protection (SWP) for risk prevention and in-plant treatment technologies for risk management. Notably, all of**the barriers in this framework must be effective to ensure drinking water security. Climate change-associated**disturbances (wildfires, hurricanes, floods) have revealed alarming inadequacies in current implementations of**the multi-barrier approach. These disturbances are causing increasingly variable or deteriorated source quality,**and challenging in-plant treatment technologies beyond design and operational response capacities, to the point**of service disruptions. Water industry consensus points to the pressing need for new SWP technologies for**climate change adaptation to ensure secure community water systems. In Canada, effective SWP must focus on**forested source watersheds because that is where the drinking water for most urban, rural, and Indigenous**communities originates. Healthy forests typically produce high quality water-the value of natural storage and**filtration of water by global forests has been estimated at $4.1 trillion. Forest management approaches have**been suggested as SWP technologies and include thinning or prescribed burning for pre-emptive risk reduction**or reactive effects mitigation of potentially catastrophic disturbances. While forest management impacts on**water have been well studied, little if any of that work has focused specifically on drinking water treatability,**which will likely vary in regionally. The forWater Network will provide new knowledge regarding the impacts**of different forest management strategies on drinking water source quality and treatability to assess their**suitability as SWP technologies across the major ecological/forest regions of Canada.
