abstract = {Impacts on wetlands are becoming more pressing every day. Among them, habitat loss,
overexploitation of aquifers and changes in land use are considered the most important. However, the
impacts linked to wastewater discharges are increasing worldwide. In this context, this study analyses
the impacts of input of wastewater to a Mediterranean Ramsar temporary wetland (Fuente de Piedra,
south of Spain). To this end, systematic sampling was carried out in the Charcón stream which
receives water from a wastewater treatment plant (WWTP) and discharges it into the wetland. The
results showed a slight decrease in the nutrient concentrations, particularly for nitrogen compounds.
Heterotrophic and fecal bacteria concentration, as well as phytoplankton and zooplankton abundance
and biomass, all significantly decreased from the treatment plant to the wetland. When comparing
the effect of this discharge with other similar occurring to the same wetland, it was evident that the
Charcón stream was responsible for a greater impact. At this point, it is relevant to note that the
main difference among both treated wastewater discharges lies in the different water retention time
once the wastewater was released from the WWTP. In fact, we recommend an increase in the water
retention time by building seminatural ponds, together with the use of biofilters, which will notably
contribute to improve the processes of assimilation of nutrients and to decrease the impact generated
in the wetland by this spill.},
