We examine the implications of state water quality regulatory heterogeneity for waste and drinking water violations in the continental US using Environmental Protection Agency data from 2007 to 2017. Using discrete regression analyses, we find some evidence that cumulative violations are higher when additional state water quality standards are introduced. However, one year after a new standard is implemented, cumulative violations seem to decline relative to the number of violations before introducing additional regulations. Compliance may improve after introducing new standards as operations and procedures are modified, the use of inputs like disinfectants is adjusted, or technologies are upgraded in response to new standards.

国家监管异质性以及对《清洁水和安全饮用水法》的遵守

我们使用美国环境保护署（EPA）2007年至2017年的数据，研究了州水质监管异质性对美国大陆上的废物和饮用水违法行为的影响。通过离散回归分析，我们发现一些证据表明，当附加州水质标准达到标准时，累积违规率会更高介绍。但是，在实施新标准一年之后，相对于违规数量而言，累积的违规行为似乎有所减少，之后又引入了其他法规。在引入新标准后，随着操作和程序的修改，对消毒剂等投入物的使用的调整或对技术的更新以响应新标准，合规性可能会得到改善。
