美国环境保护署（EPA）向环境金融中心网络（EFCN）发布了一份合同，以试验一种统一的或基于资源的水源保护方法。这种方法涉及将共享相同或相似水源或其他统一特征（如政治边界）的多个水系统集合在一起，为每个系统制定一个水源保护计划，而不是一个计划。该项目涉及8个不同州的工作。在这项工作和之前使用这种方法的试点项目的基础上，EFCN为这种方法总结了一些经验教训。 总的来说，这种方法似乎为参与者提供了一些好处，并为水源保护提供了一种良好、合理的方法。然而，这种方法也需要相当长的时间和精力来实现这些好处。总的来说，EFCN认为这是一种保护水源免受污染的好方法。包括数字。

The US Environmental Protection Agency (EPA) issued a contract to the Environmental Finance Center Network (EFCN) to pilot a unified or resource-based approach to source water protection. This approach involves bringing together multiple water systems who share the same or similar water source or some other unifying feature, such as a political boundary, to develop one source water protection plan rather than one plan for each system. This project involves work in 8 different states. Based on this work, and a previous pilot project using this approach, the EFCN has developed some lessons learned for this approach. In general, the approach appears to offer several benefits for the participants and provides a good, sound approach for source water protection. However, the approach also requires considerable time and effort to achieve the benefits. Overall, the EFCN believes this is a good means to try to protect source waters from contamination.
