大肠杆菌噬菌体是根据地下水规则可用于监测的指标之一。不像 细菌指标表明，这些病毒具有更强的生存能力，可以作为地下水质量的更好预测因子。需要简单的大肠杆菌噬菌体方法来指示粪便和病毒对水的污染。 方法1601是一种基于性能的方法，方法性能的验收标准为 在协作测试中开发，并作为方法的一部分发布。方法的改进可能是 使用2级研究进行演示，该研究允许将该方法验证为改进的美国环境保护局（USEPA）方法。 层 2在一项多实验室研究中，使用规定的方案进行验证，在该研究中，向患者提供盲样 每个实验室都需要进行分析。对数据进行了恢复性和变异性分析 在参与的实验室里。如果结果符合方法验收标准，则使用改进的方法 被认为是美国环保局验证的水测试方法。本研究描述了一种16小时的方法 改进了方法1601，称为快速噬菌体，用于检测大肠杆菌噬菌体，使用100ml样本，带有 同一天，使用荧光指示器进行点阶跃阳性预测。包括表格，仅限扩展摘要。

Coliphage is one of the indicators that can be used in monitoring under the Ground Water Rule. Unlike bacterial indicators, these viruses have greater survivability and may serve as better predictors of groundwater quality. Simple coliphage methods are needed to indicate fecal and viral contamination of water. Method 1601 is a performance based method where acceptance criteria for method performance were developed in collaborative testing and published as part of the method. Method improvements may be demonstrated using a Tier 2 study which allows the method validated as an improved U.S. Environmental Protection Agency (USEPA) method. Tier 2 validation is done using a prescribed protocol in a multi-lab study where blind samples are provided to each lab for analysis. The data are analyzed with respect to both recovery and variability within and across the participating labs. If the results meet the method acceptance criteria, the improved method is considered a USEPA validated method for use in water testing. This study describes a 16 hr method modification of Method 1601, called Fast Phage™, for the detection of coliphage using a 100ml sample with a same day spot step positive prediction using a fluorescent indicator.
