摘要

There are over 100 models that have been developed for predicting trihalomethanes (THMs),rnhaloacetic acids (HAAs), bromate, and unregulated disinfection byproducts (DBPs). Until nowrnno publication has evaluated the variability of previous THM and HAA models using a commonrndata set. In this poster, the standard error (SE), Marquardt’s percent standard deviation (MPSD),rnand linear coefficient of determination (R2) were used to analyze the variability of 87 modelsrnfrom 23 different publications; this paper highlights some of the results. The most robust modelsrnwere capable of predicting THM4 with an SE of 48 μg/L and HAA6 with an SE of 15 μg/L, bothrnachieving R~2 > 0.90. The majority of models were formulated for THM4. There is a lack ofrnpublished models evaluating total HAAs, individual THM and HAA species, bromate, andrnunregulated DBPs.
