由于气候条件恶劣，设备和加工化学品的运输选择有限，以及殖民主义的持续影响，获得清洁和安全的饮用水一直是北极社区关注的问题。在一年的时间里，他们从加拿大努纳武特一个分散的卡车饮用水系统的多个地点收集了水样。结果表明，使用点的饮用水质量受到水源和个别建筑物条件的影响，并强烈表明，在水龙头处测量的铅和铜与现场房屋管道部件的腐蚀有关。通过荧光数据的区域整合确定，腐殖质样物质是所有样品中主要的有机组分。水源水和整个水系中的铁和锰含量在冬季较高，在夏季较低。在一些建筑物的自来水中检测到铜（>2000µg L-1）和铅（>5µg L-1）浓度升高。现场流分馏与ICP-MS和UV-Vis光谱仪相结合，用于证明水源水特征（高有机物，铁，锰）与使用点饮用水中的铅和铜之间的联系。
Access to clean and safe drinking water is a perpetual concern in Arctic communities due to challenging climatic conditions, limited options for the transportation of equipment and process chemicals, and the ongoing effects of colonialism. Water samples were gathered from multiple locations in a decentralized trucked drinking water system in Nunavut, Canada, over the course of one year. The results indicate that point of use drinking water quality was impacted by conditions in the source water and in individual buildings and strongly suggest that lead and copper measured at the tap were related to corrosion of onsite premises plumbing components. Humic-like substances were the dominant organic fraction in all samples, as determined by regional integration of fluorescence data. Iron and manganese levels in the source water and throughout the water system were higher in the winter and lower in the summer months. Elevated concentrations of copper (>2000 µg L-1) and lead (>5 µg L-1) were detected in tap water from some buildings. Field flow fractionation coupled with an ICP-MS and a UV-Vis spectrometer was used to demonstrate the link between source water characteristics (high organics, iron, manganese) and lead and copper in point of use drinking water.
