Abstract
Treated wastewater use for irrigation is, nowadays, the more relevant reutilization alternative of wastewater, if it is developed with sanitary and environmental warranties.
Giardia lamblia and Cryptosporidium spp. two wide distributed enteric pathogen protozoan, which are frequent in aquatic habitats. These protozoan investigation and detection have acquired importance in the last years due to their dispersion forms, which show resistance to the habitual treatments of potabilization and purification, and their classification as emerging pathogens which are the causative agents of important hydrical transmission outbreaks.
In our work, Giardia lamblia cyst and Cryptosporidium spp. oocyst presence in Santa Cruz de Tenerife treated wastewater which is transported to the South of the island to be reutilised in agriculture. Furthermore, transport, storage and advanced treatment effects against cyst and oocyst concentration throughout the system and relation existence with other bacteriological and physical-chemical parameters, are also investigated.
The obtained results demonstrate variable behaviours in cyst and oocyst concentration against applied treatments, and the depurative effect of the long-distance transport which seems to have in treated wastewater.
There was not found any relation between cyst and oocyst concentration in treated wastewater and the traditional indicators of faecal contamination.
