Research to date has provided limited insight into the complexity of water-borne pathogen transmission. Private well water supplies have been identified as a significant pathway in infectious disease transmission in both the industrialised and the developing world. Using over 90,000 private well water submission records representing approximately 30,000 unique well locations in south-eastern Ontario, Canada, a spatial analysis was performed in order to delineate clusters with elevated risk of E. coli contamination using 5 years of data (2008-2012). Analyses were performed for all years independently and subsequently compared to each other. Numerous statistically significant clusters were identified and both geographic stability and variation over time were examined. Through the identification of spatial and temporal patterns, this study provides the basis for future investigations into the underlying causes of bacterial groundwater contamination, while identifying geographic regions that merit particular attention to public health interventions and improvement of water quality.
迄今为止的研究对水传播病原体传播的复杂性了解有限。在工业化国家和发展中国家，私人井水供应都被确定为传染病传播的重要途径。利用代表加拿大安大略省东南部约30000个独特水井位置的90000多条私人井水送检记录，进行了一项空间分析，以便利用5年的数据（2008 - 2012年）描绘大肠杆菌污染风险升高的聚集区。对所有年份分别进行分析，随后相互比较。识别出了许多具有统计学意义的聚集区，并研究了地理稳定性和随时间的变化。通过识别空间和时间模式，本研究为未来调查细菌地下水污染的潜在原因提供了基础，同时确定了值得特别关注公共卫生干预措施和改善水质的地理区域。
