1661496 (Edwards). Following a massive flood in Louisiana, this RAPID grant will help assist private well owners in the area assess and address the current safety of their potable water supply. Climate models predict that the frequency of flooding will increase in Louisiana and elsewhere in the U.S. The 47 million residents in the U.S. reliant on well water, half of which normally test positive for microbial contamination, would benefit from a better understanding of one-time disinfection protocols.After natural disasters, residents need low-cost, effective remediation options to ensure safe, clean drinking water. Shock chlorination is the primary disinfection method for microbial contamination in wells, but evidence suggests that this approach may not be appropriate under all conditions, the actual disinfection effect may be short-lived or incomplete, and there may be short-term increases in metals such as lead. The recent flooding event in Louisiana offers a unique opportunity to characterize well water quality after a flood, evaluate both natural and enhanced recovery after treatments such as shock chlorination, and assess public health issues experienced by low-income well owners using compromised wells.

1661496(爱德华兹)。在路易斯安那州发生大规模洪灾后，这笔快速赠款将帮助该地区的私人水井所有者评估和解决他们目前的饮用水供应安全问题。气候模型预测，路易斯安那州和美国其他地区的洪水频率将会增加。美国4700万依赖井水的居民将受益于更好地了解一次性消毒方案。这些居民中有一半通常微生物污染检测呈阳性。自然灾害发生后，居民需要低成本、有效的补救方案，以确保安全、清洁的饮用水。冲击氯化是井中微生物污染的主要消毒方法，但有证据表明，这种方法并不是在所有条件下都适合，实际消毒效果可能是短暂的或不完整的，铅等金属可能会短期增加。路易斯安那州最近发生的洪灾事件提供了一个独特的机会来描述洪灾后的井水质量，评估自然恢复和经过冲击氯化处理后的强化恢复，以及评估低收入井主使用受损油井所经历的公共卫生问题。
