在西澳大利亚州珀斯的一些地区，由于地下水经过处理，出现了沼泽气味。当氯气需求得不到满足时，由二甲基三硫化物引起的气味在供水总管中产生。当出现沼泽气味时，冲洗水管可以减少投诉数量。添加2 mg/L或更多的氯也消除了沼泽味。为了控制干管中沼泽气味的形成，在地下水处理厂的出口处额外添加了2-5 mg氯/L，从而增加了供水系统中大多数点的游离氯浓度。自从这一策略实施以来，关于沼泽气味的投诉几乎已经停止。包括55个参考文献、表格和图表。

Swampy odors occurred in some areas of Perth, Western Australia, supplied with treated groundwater. The odors, caused by dimethyl trisulfide, developed in the water supply mains when chlorine demand was not satisfied. When swampy odors occurred, flushing of water mains reduced the number of complaints. The addition of 2 mg/L or more of chlorine also eliminated the swampy odor. To control the formation of swampy odors in mains, an extra 2-5 mg chlorine/L was added at the outlet of the groundwater treatment plant, thereby increasing the concentration of free chlorine at most points in the water supply system. Since this strategy was instituted, complaints of swampy odors have almost ceased. Includes 55 references, tables, figures.
