建议降低三卤甲烷（THM）的最高污染物水平可能会迫使许多公用事业公司更换消毒剂或改变处理过程。面对这种可能性，更多的公用事业公司正在考虑使用颗粒活性炭去除痕量有机物。本文介绍了从五个地点收集的去除三卤甲烷及其前体和替代物的性能和成本数据。包括19个参考文献、表格和图表。

Suggested reduction of the maximum contaminant level for trihalomethanes (THMs) could force many utilities to change disinfectants or to alter treatment processes. Faced with this possibility, more utilities are considering granular activated carbon for trace organics removal. This article presents performance and cost data, collected from five sites, for the removal of THMs, their precursors, and surrogates. Includes 19 references, tables, figures.
