Variations in trihalomethane (THM) levels during two-day period in the advanced treated water which had passed through a building's plumbing system (stored water) were compared with those in the advanced treated water delivered directly by the distribution system. THM levels in both the water were relatively uniform. The water quality deterioration measured by the increased THMs was apparently observed during the storage of the water in the plumbing system, even though the advanced treatment could produce high-quality water. Annual changes in THM in the stored water were also examined. Increasing air temperature increased THMs levels except for bromoform.
将经过建筑物管道系统的深度处理水（储存水）在两天内三卤甲烷（THM）水平的变化与由分配系统直接输送的深度处理水的变化进行了比较。两种水中的THM水平相对均匀。尽管深度处理能够产生高质量的水，但在管道系统中储存水的过程中，明显观察到THM增加所衡量的水质恶化情况。还研究了储存水中THM的年度变化。除溴仿外，气温升高会使THM水平增加。
