在估算有机物法规的成本时，美国环境保护局（EPA）开发了一系列单元工艺的资本、运营和维护成本设计，并将其作为给定设计参数的函数呈现。这些费用可分为与控制三卤甲烷有关的费用和与安装颗粒活性炭以控制成品饮用水供应中的合成有机物有关的费用。由此产生的成本增加估计前者为5%，后者为25%。还包括替代消毒方法和成本，如臭氧、二氧化氯以及运行和维护成本。包括11个参考文献、表格、图表。

In estimating costs for the organics regulations the U.S. Environmental Protection Agency (EPA) developed capital and operations and maintenance costs designs for a series of unit processes and presented them as a function of a given design parameter. These costs may be categorized as those associated with control of trihalomethanes and those associated with the installation of granular activated carbon for control of synthetic organics in finished drinking water supplies. The resulting cost increases are estimated at 5 percent for the former and 25 percent for the latter. Also covered are alternative disinfection methods and costs such as ozone, chlorine dioxide, and operation and maintenance costs. Includes 11 references, tables, figures.
