Abstract：
Consolidation of multi-domain risk management research is essential for strategies facilitating the concerted government (educational) and population-level (behavioural) actions required to reduce microbial private groundwater contamination. However, few studies to date have synthesised this literature or sought to ascertain the causal generality and extent of supply contamination and preventive responses. In light of the Republic of Ireland (ROI) and Ontario\'s high reliance and research focus on private wells and consequent utility for empirical comparison, a scoping review of pertinent literature (1990-2022) from both regions was undertaken. The SPICE (Setting, Perspective, Intervention, Comparison, Evaluation) method was employed to inform literature searches, with Scopus and Web of Science selected as primary databases for article identification. The review identified 65 relevant articles (Ontario = 34, ROI = 31), with those investigating well user actions (n = 22) and groundwater quality (n = 28) the most frequent. A markedly higher pooled proportion of private supplies in the ROI exhibited microbial contamination (38.3 % vs. 4.1 %), despite interregional similarities in contamination drivers (e.g., weather, physical supply characteristics). While Ontarian well users demonstrated higher rates of historical (≥ 1) and annual well testing (90.6 % vs. 71.1 %; 39.1 % vs. 8.6 %) and higher rates of historical well treatment (42.3 % vs. 24.3 %), interregional levels of general supply knowledge were analogous (70.7 % vs. 71.0 %). Financial cost, organoleptic properties and residence on property during supply construction emerged as predictors of cognition and behaviour in both regions. Review findings suggest broad interregional similarities in drivers of supply contamination and individual-level risk mitigation, indicating that divergence in contamination rates may be attributable to policy discrepancies - particularly well testing incentivisation. The paucity of identified intervention-oriented studies further highlights the importance of renewed research and policy agendas for improved, targeted well user outreach and incentivised, convenience-based services promoting routine supply maintenance.
摘要：
整合多领域风险管理研究对于促进减少微生物私人地下水污染所需的协调政府（教育）和人口（行为）行动的战略至关重要。然而,迄今为止，很少有研究综合了这些文献，或试图确定供应污染和预防措施的因果关系和程度。鉴于爱尔兰共和国（ROI）和安大略省的高度依赖和研究重点是私人水井和随之而来的效用进行经验比较，对两个地区的相关文献(1990-2022年)进行了范围审查.SPICE（设置，Perspective,干预,比较,评估)方法被用来告知文献检索，选择Scopus和WebofScience作为文章识别的主要数据库。审查确定了65篇相关文章(安大略省=34，ROI=31)，那些调查井用户行为(n=22)和地下水质量(n=28)的人最频繁。ROI中私人用品的合并比例明显较高，表现出微生物污染(38.3%与4.1%)，尽管在污染驱动因素方面存在区域间的相似性(例如，天气,实物供应特征)。虽然Ontarian井用户表现出更高的历史（≥1）和年度试井率（90.6%与71.1%；39.1%与8.6%）和更高的历史井处理率（42.3%与24.3%），区域间一般供应知识水平相似(70.7%与71.0%）。财务成本,供应建设过程中的感官特性和对财产的居住成为两个地区认知和行为的预测因子。审查结果表明，在供应污染和个人层面风险缓解的驱动因素方面，区域间存在广泛的相似性，表明污染率的差异可能归因于政策差异-特别是良好的测试激励。缺乏已确定的面向干预的研究，这进一步突出了更新研究和政策议程对改进的重要性，有针对性的用户外展和激励，促进日常供应维护的便民服务。
