This study examines the public's perceptions of the ecological restoration of the Congost River over the past thirty years, focusing on the period between 2010 and 2022. We conducted a survey of 112 river users across five key zones identified through a pilot study for their high pedestrian density, aiming to analyse how different sociodemographic groups perceive the river's ecological state. A structured questionnaire was distributed along both sides of the river to engage a diverse range of individuals typically utilizing the river environment.

- In the Mediterranean region, water scarcity negatively impacts stream water quality, particularly below wastewater treatment plants (WWTP).
- The study examined four helophyte species to evaluate their effectiveness in reducing dissolved inorganic nitrogen (N) and phosphorus (P) from WWTP effluents over an 11-month period.
- Results showed that the highest concentrations of N and P occurred in different plant parts, with Iris pseudoacorus being the most efficient in retaining nutrients, suggesting helophytes could help improve water quality in ecosystems affected by wastewater.
Wastewater treatment plant (WWTP) effluents are sources of dissolved organic carbon (DOC) and inorganic nitrogen (DIN) to receiving streams, which can eventually become saturated by excess of DIN. Aquatic plants (i.e.
