本研究的目的 该项目旨在开发一个特定于现场的水质模型，以模拟三卤甲烷（THMs）的形成 以及乔治亚州格温内特县配水系统中使用 一阶饱和增长模型与配电系统建模程序WaterCAD。 这些模型预测结果与现场采样的测量值进行了比较。这个 建模工作取得了不同程度的成功。HAA建模的结果 似乎相当成功，预测值和测量值之间有更好的一致性 浓度高于THM建模。而实测结果和预测结果是一致的 统计上不同的是，结果在确定水的相对变化方面具有实用价值 在整个配送系统的各个位置都能达到预期的质量。结果 提供了配水系统对水质和环境影响的合理指示 能够使用配电系统水力建模软件对THMs和HAAs进行建模。 包括11个参考文献、表格、图表。

The goal of this research project was to develop a site-specific water quality model to simulate the formation of trihalomethanes (THMs) and haloacetic acids (HAAs) (all nine species) in the Gwinnett County, Georgia water distribution system using a first-order saturation growth model with the distribution system modeling program WaterCAD. These model predictions were compared with measured values from field sampling. The modeling effort produced results with varying success. The results from the HAA modeling appeared to be reasonably successful, having better agreement between predicted and measured concentrations than the THM modeling. While the measured and predicted results were statistically different, the results were of practical value in determining relative changes in water quality that can be expected at various locations throughout the distribution system. The results provided a reasonable indication of the effects of the distribution system on water quality and on the ability to model THMs and HAAs with distribution system hydraulic modeling software.
