The application of remote surveillance to the identification of polluted discharges to controlled waters arising from major civil engineering works was investigated in this scoping study. A combination of spectral imaging and aerial photography was able to identify water treatment processes and discharges to watercourses to a similar degree of effectiveness to personal inspection, but could not improve on it. The technique would therefore be most appropriate to overview large sites that are not routinely audited by ground-level inspection. This may limit its usefulness to some extent but it nonetheless can perform well in this overview role. Remote surveillance mapping of stressed vegetation was shown to be a useful adjunct to the identification of contaminated land and, by implication, the extent of contamination of its associated surface water. The study indicated that a more intensive interpretation of remote imaging spectra together with the use of other GIS-based techniques may further improve the potential of remote surveillance to detect contaminated land, and this approach is recommended for further investigation.
