Impact of treated wastewater on groundwater quality in the region of Tiznit (Morocco)
The Tiznit region has an arid to semi-arid climate. Rainfall is scarce and the reuse of wastewater for crop irrigation is common, and consequently groundwater can be contaminated by chemical and biological pollutants. A wastewater treatment plant is constructed with the aim of producing water suitable for reuse in agriculture and reducing groundwater pollution. The aim of this study is to assess ...

The potential to improve water quality in the middle Rio Grande through effective wetland restoration
The Rio Grande, which forms the United States—Mexico border for much of its course, receives diverse pollutants from both urban and agricultural areas, most notably in the sister cities of El Paso (TX, USA)—Ciudad Juárez (CHI, Mexico). This study aimed to describe regional trends in water quality in waters near the El Paso–Ciudad Juárez metroplex and to examine the potential for water quality ...

Nitrogen And Phosphorus Removal In Substrate-Free Pilot Constructed Wetlands With Horizontal Surface Flow In Uganda
In constructed wetlands (CWs) with horizontal sub-surface flow, nutrient removal, especially phosphorus, is limited because the root biomass fills the pore spaces of the substrate (usually gravel), directing wastewater flow to deeper wetland media, plants are not regularly harvested, the litter formed by decomposing vegetation remains on the surface of the substrate and thus does not interact ...
