The frequency and severity of flooding events will increase over the coming decades due to global climate change. While close attention has typically been paid to infrastructural and environmental outcomes of flood events, the potential adverse human health consequences associated with post-event consumption from private groundwater sources have received minimal attention, leading to a poor understanding of private well users’ preparedness and the drivers of positive behavioural adoption. The current study sought to quantify the capacity of private well users to cope with flood-triggered contamination risks and identify the social psychological determinants of proactive attitudes in the Republic of Ireland, using a cross-sectional questionnaire incorporating two distinct models of health behaviour, the Health Belief Model and Risk-Attitude-Norms-Ability-Self Regulation model. Adoption of healthy behaviours prior to flooding was evaluated with respect to respondents’ risk exposure, risk experience and risk perception, in addition to systematic supply stewardship under normal conditions. Associations between adoption of protective behaviours and perception, experience and socio-demographic factors were evaluated through multinomial and multiple logistic regressions, while a multi-model inferential approach was employed with the predictors of health behaviour models. Findings suggest that floods are not considered likely to occur, nor were respondents worried about their occurrence, with 72.5% of respondents who reported previous flooding experience failing to adopt protective actions. Prior experience of well water contamination increased adoption of proactive attitudes when flooding occurred (+47%), with a failure to adopt healthy behaviours higher among rural non-agricultural residents (136%). Low levels of preparedness to deal with flood-related contamination risks are a side-effect of the general lack of appropriate well stewardship under normal conditions; just 10.1% of respondents adopted both water treatment and frequent testing, in concurrence with limited risk perception and poor awareness of the nexus between risk factors (e.g. floods, contamination sources) and groundwater quality. Perceived risk, personal norms and social norms were the best predictors of protective behaviour adoption and should be considered when developing future awareness campaigns.

由于全球气候变化，未来几十年洪水泛滥的频率和严重性将增加。尽管通常会密切关注洪水事件的基础设施和环境后果，但与私人地下水源事后消费相关的潜在的不利人类健康后果却很少受到关注，从而导致人们对私人井的使用者的准备工作和对水的认识不足。积极的行为采用的驱动力。当前的研究试图通过结合两种截然不同的健康行为模式的问卷调查，来量化爱尔兰共和国应对洪水引发的污染风险并确定积极态度的社会心理决定因素的能力。健康信念模型和风险态度规范能力自我调节模型。除了在正常情况下进行系统的供应管理外，还针对受访者的风险暴露，风险经验和风险感知，评估了洪水之前采取健康行为的情况。通过多项和多元logistic回归评估保护行为的采用与感知，经验和社会人口统计学因素之间的关联，同时采用多模型推论方法与健康行为模型的预测指标进行比较。调查结果表明，既不认为可能发生洪水，也不认为受访者担心洪水的发生，有72.5％的受访者表示先前的洪水经历未能采取保护措施。先前的井水污染经验使发生洪水时采取积极态度的态度增加了（+ 47％），农村非农业居民中没有采取较高的健康行为（136％）。应对洪水相关污染风险的准备水平低是正常情况下普遍缺乏适当油井管理的副作用；仅有10.1％的受访者同时接受了水处理和频繁测试，这与有限的风险感知以及对风险因素（例如洪水，污染源）和地下水质量之间关系的认识不足有关。感知的风险，个人规范和社会规范是采用保护性行为的最佳预测指标，在开展未来的宣传活动时应予以考虑。应对洪水相关污染风险的准备水平低是正常情况下普遍缺乏适当油井管理的副作用；仅有10.1％的受访者同时接受了水处理和频繁测试，这与有限的风险感知以及对风险因素（例如洪水，污染源）和地下水质量之间关系的认识不足有关。感知的风险，个人规范和社会规范是采用保护性行为的最佳预测指标，在开展未来的宣传活动时应予以考虑。应对洪水相关污染风险的准备水平低是正常情况下普遍缺乏适当油井管理的副作用；仅有10.1％的受访者同时接受了水处理和频繁测试，这与有限的风险感知以及对风险因素（例如洪水，污染源）和地下水质量之间关系的认识不足有关。感知的风险，个人规范和社会规范是采用保护性行为的最佳预测指标，在开展未来的宣传活动时应予以考虑。污染源）和地下水质量。感知的风险，个人规范和社会规范是采用保护性行为的最佳预测指标，在开展未来的宣传活动时应予以考虑。污染源）和地下水质量。感知的风险，个人规范和社会规范是采用保护性行为的最佳预测指标，在开展未来的宣传活动时应予以考虑。
