The Pierre Auger Observatory has thecapability of detecting ultra-high energy neutrinos.The method adopted is to search for very inclined young showers. The properties of such showers that start deep in the atmosphere are very different at ground level from those of showers initiated in theupper atmosphere by protons or nuclei. The neutrino events would have a significant electromagnetic component leading to a broad time structure of detected signals in contrast to nucleonic-induced showers. In this paper we present several observables that are being used to identify neutrino candidates and show that the configuration of the surface detectors of the Auger Observatory has a satisfactory discrimination power against the larger background of nucleonicshowers over a broad angular range.
