Trihalomethanes (THMs) and haloacetic acids (HAAs) are two classes ofdisinfection byproducts (DBPs) that have been implicated in adverse reproductive health outcomes, including spontaneous abortion, birth defects, and low birth weights. Epidemiological research into the health effects of DBPs relies heavily on assessing the exposure of target populations to these contaminants, particularly in drinking water. The goal of this study was to assess the effectiveness of using commercially-available distribution system modeling to predict DBP levels at the model node nearest to the consumer's tap. If successful, this approach could provide a better understanding of DBP levels over both time and space within a distribution system. Includes 10 references, tables, figures.
