这项研究评估了2012年科罗拉多州卡奇拉波德河流域的High Park Wildfire对水源水质和水处理的影响。通过在均匀生成条件下用氯气处理水样来评价消毒副产物(DBPs)的形成。此外，还评价了明矾混凝降低溶解有机碳(DOC)和DBP浓度的效果。与基流条件相比，野火后的雷雨和春季融雪增加了DOC和DBP的浓度。明矾凝聚能有效地降低DOC浓度(50 mg/L时降低30-60%)和DBP生成(即50 mg/L时总三卤代甲烷减少60-80%)。柯林斯堡水处理设施对High Park WildFire的反应是加强环境监测，使用多种供水系统，并在火灾发生后的第二年建造一个预沉淀池，以有效地向客户提供高质量的饮用水。
This study evaluated effects of the 2012 High Park Wildfire in the Cache la Poudre River Watershed in Colorado on source water quality and water treatment. The formation of disinfection by‐products (DBPs) was evaluated by treating water samples with chlorine following uniform formation conditions. The efficacy of alum coagulation for reducing dissolved organic carbon (DOC) and DBP concentrations was also evaluated. Postwildfire thunderstorms and spring snowmelt increased DOC and DBP concentrations relative to base‐flow conditions. Alum coagulation effectively reduced DOC concentrations (by 30–60% at a dose of 50 mg/L) and DBP formation (i.e., total trihalomethanes reduced by 60–80% at a dose of 50 mg/L). The Fort Collins water treatment facility responded to the High Park Wildfire by increasing environmental monitoring, using multiple water supplies, and constructing a presedimentation basin to effectively deliver high‐quality drinking water to its customers in the year following the fire.
