The effect of five process variables on the transformation of 16 selected PPCP/EDCs during drinking water ozonation was systematically studied through 25-1 fractional factorial designed experiments. Dissolved Organic Carbon (DOC) content, ozone dose, and their interaction were most significant for all 16 compounds, and accounted for 60--98% of the observed variability in the transformation efficiencies. Temperature was a significant factor for most of the fast-reacting compounds (kO3 >10 4 M-1s-1), accounting for up to 20% of the change in transformation efficiency, but was not significant for the slow-reacting compounds (kO3 <103 M -1s-1). Ozone exposure of > 1.0 mg L-1 min-1 resulted in > 80% transformation of all the 16 compounds at both low (5 °C) and high (23 °C) temperatures. However, this transformation is expected to be strongly dependent on the nature of the DOC for the slow-reacting compounds.
