Comment on "Using Bayesian statistics to estimate the coefficients of a two-component second-order chlorine bulk decay model for a water distribution system" by Huang, J.J., McBean, E.A. Water Res. (2007)

Huang and McBean (2007) rightly pointed out that an accurate model of chlorine decay in bulk water plays an important role in meeting disinfection goals in water distribution systems. The development of a two-component second-order model of chlorine decay in bulk water was a significant step in the logical progression towards more accurate representation of the many complex processes contributing to such decay. It is therefore important to ensure that this and related developments are attributed correctly to those who made them. It is even more important to ensure that the analytical solution to this model is correct, because many other models have been based upon it, as Huang and McBean (2007) recognised.
