  The long-range contribution to dispersion forces is known to have a major
impact on the properties of inhomogeneous fluids, and its correct treatment is
increasingly recognized as being a necessary requirement to avoid
cutoff-related artefacts. Although analytical corrections for quantities like
the surface tension are known, these can not take into account the structural
changes induced by the long-range contributions. Here, we analyze the
interfacial properties of seven popular water models, comparing the results
with the cut-off version of the dispersion potential. The differences in
surface tension estimates are in all cases found to be less than 2 mN/m.
