在一项可能影响即将到来的地下水规则的研究中， 本文作者认为，由于 地下水中广泛存在病毒，大多数情况下 供水在分配前应进行消毒。科学的 需要数据来支持即将到来的规则，这项研究 提供了现场地下水病毒污染的快照 国家一级。 这篇文章关注的是关于疾病发生的信息 水源水中的病原体和微生物指标及其应用 与水等不同非生物参数的关系 地下水的质量、地质构造和其他因素。 根据其地质特征选择场地 与全国地下水资源概况相匹配。两个不同的 微生物方法被用来检测地下水中的病毒 来源，并在研究期间采用了新的微生物检测方法 进行了实地测试。结果表明，当一个测试良好的 一旦任何一种生物检测呈阳性，就很可能进行检测 在未来的抽样中呈阳性。 本文还提供了一种策略来预测 地下水会导致粪便污染。包括32个参考文献、表格和图表。

In a study that may affect the upcoming Ground Water Rule, the authors of this article determined that because of the widespread occurrence of virus in groundwater, most well water supplies should be disinfected before distribution. Scientific data were needed to support the upcoming rule, and this study provides a snapshot of viral contamination of groundwater at the national level. This article looks at information regarding the occurrence of pathogens and microbial indicators in source waters and their relationships with different abiotic parameters such as water quality, geologic formation of groundwater sites, and other factors. Sites were selected based on their geological characteristics to match the national profile for groundwater sources. Two different microbial methods were used to detect viruses in groundwater sources, and during the study a new microbial detection methodology was field-tested. Results indicate that when a well tested positive once for any of the biological assays, it was likely to test positive in future samplings. This article also offers a strategy to predict the vulnerability of groundwater supplies to fecal contamination. Includes 32 references, tables, figures.
