- Empirically Based Models(174 pp, 3.46 MB, August 1998, EPA 815-R-98-005, About PDF)
This report documents the development of empirically-based models used for predicting trihalomethanes, haloacetic acids, chloral hydrate, and bromate. The models can be used to assess the impact of changing water quality conditions on disinfection byproduct products (DBP) formation or to evaluate the impact of treatment modifications and were used in part in the Water Treatment Plant (WTP) Model v2.0 and Surface Water Analysis Tool (SWAT) v1.1.
