希金斯维尔市是密苏里州中北部的一个农村社区，该市从蓄水池中获取饮用水，蓄水池定期收集农业径流，其中s-三嗪含量较高。希金斯维尔水处理厂成为密苏里州第一家使用颗粒活性炭（GAC）过滤吸附器控制除草剂的水厂。希金斯维尔的四个多媒体重力过滤器中的两个通过更换安特拉石盖，用24英寸的GAC进行了改装。本文介绍了希金斯维尔水处理厂GAC过滤吸附器的性能评估。包括9个参考文献、表格、图表。

The City of Higginsville, a rural community in north central Missouri, obtainsits drinking water from an impoundment that collects agricultural runoff periodically containing elevated levels of s-triazines. The Higginsville Water Treatment Plant became the first water plant in Missouri to use granular activated carbon (GAC) filter-adsorbers for herbicide control. Two of the four multi-media gravity filters at Higginsville were retrofitted with 24 inches of GAC by replacement of theanthracite caps. This paper presents an evaluation of the performance of GAC filter-adsorbers at the Higginsville Water Treatment Plant. Includes 9 references, table, figures.
