为了简化对越来越多污染物的监测，美国环境保护署建立了“标准化监测框架”该框架将第一阶段挥发性有机污染物监测与第二阶段监测要求同步。标准化监测框架是针对与慢性健康影响相关的源相关污染物制定的:挥发性有机化学品（VOCs）、农药、放射性核素和大多数无机化学品。所有公共供水系统将遵循九年的合规周期，分为三年合规期。各州将根据系统规模、脆弱性等标准为各种系统指定启动日期。在最初的三年合规期内，各州必须安排约三分之一的水系统在每年进行监测。本文详细介绍了该计划。 包括4个参考文献、图表。

To simplify monitoring of an ever-increasing number of contaminants, the US Environmental Protection Agency established the "standardized monitoring framework." This framework synchronizes Phase I volatile organic contaminant monitoring with Phase II monitoring requirements. The standardized monitoring framework was developed for source-related contaminants associated with chronic health effects: volatile organic chemicals (VOCs), pesticides, radionuclides, and most inorganic chemicals. All public water systems will be subject to a nine-year compliance cycle, divided into three-year compliance periods. States will assign starting dates to various systems, based on criteria such as system size, vulnerability, and so forth. States must schedule about one third of the total water systems to monitor during each year of the initial three-year compliance period. This article describes the schedule in detail.
