评估了10个小型公共供水系统是否符合地表水处理规则，并在本文中给出了其中两个系统的详细调查结果报告。这两个系统的浊度大于0.5 NTU。解释了在使每个系统符合要求时遇到的问题，以及相关的可能资本成本。基于对所有10个系统的研究，给出了五个一般性结论。

Ten small public water systems were evaluated for compliance with the Surface Water Treatment Rule, and detailed reports of the findings for two of the systems were presented in this paper. These two systems have turbidities greater than 0.5 NTU. The problems encountered in bringing each system into compliance are explained, along with the associated probable capital costs. Five general conclusions, based on the study of all 10 systems, are given.
