本研究旨在评估水处理对可生物降解有机物（BOM）水平的影响，并描述处理变化对模型分配系统内监测的细菌水质的影响。该项目调查了以下内容:常规水处理过程中的营养物去除；生物过滤对进入分配系统的营养水平的影响；以及模型分配系统中营养物浓度降低对细菌水质的影响。

This study was conducted to assess the impact of water treatment on biodegradable organic matter (BOM) levels and to characterize the impact of treatment changes on bacterial water quality monitored within model distribution systems. The project investigated the following: nutrient removal during conventional water treatment; the effects of biological filtration on nutrient levels entering the distribution systems; and, the effect of a decrease in nutrient concentration on bacterial water quality in model distribution systems.
