Mass-transfer processes of paramount importance, such as reaeration and volatilization, occur at the air–water interface. Particularly, volatilization is intensively studied because it can be a relevant removal process for toxic contaminants from flowing and standing surface waters. The paper provides a comparison among predictive equations available from literature for standing waters for the case of MTBE contamination. Most of the considered equations tend to overestimate the volatilization rate, while three equations offer a good fit with the observed data. Finally, these equations are applied to a larger amount of field data.
