Los microplásticos (MP) constituyen una de las formas de contaminación más omnipresentes en nuestro planeta. Pese a ello, en comparación con los ecosistemas marinos, lagos o ríos, destaca la escasez de estudios que han tratado sobre su presencia en el suelo y en las aguas subterráneas. Con el objetivo de evaluar el impacto de los usos del suelo y o...
In small populations and scattered communities, wastewater treatment through vegetation filters (VFs), a nature-based solution, has proved to be feasible, especially for nutrient and organic matter removal. However, the presence of pharmaceuticals in wastewater and their potential to infiltrate through the vadose zone and reach groundwater is a dra...
In wastewater treatment using Vegetation Filters (VFs), natural processes reduce contaminants present in water although some of them can reach the environment. In this study, 39 contaminants of emerging concern (CECs) are evaluated in a pilot VF under different operating conditions during almost four years. The use of woodchip amendments and the ch...
As non-conventional wastewater treatment, vegetation filters make the most of the natural attenuation processes that occur in soil to remove contaminants, while providing several environmental benefits. However, this practice may introduce contaminants of emerging concern (CECs) and their transformation products (TPs) into the environment. A potent...
Nonconventional wastewater treatments, such as vegetation filters (VFs), are propitious systems to attenuate contaminants of emerging concern (CECs) in small municipalities. The development of standardised multiresidue and multimatrix methods suitable for measuring a reliable number of CEC in environmental samples is crucial for monitoring infiltra...
In urban and periurban areas, agricultural soils are often irrigated with surface water containing a complex mixture of contaminants due to wastewater treatment plant (WWTP) effluent discharges. The unplanned water reuse of these resources for crop irrigation can represent a pathway for contaminant propagation and a potential health risk due to the...
In times when environmental concerns are on the rise and the search of ways to reduce waste generation and to create a circular economy is booming, Nature Based Solutions (NBSs) play a very important role. Vegetation Filters (VFs) are a type of Land Application System (LAS) in which wastewater is used to irrigate a forestry plantation to treat the...
Vegetation Filters (VFs) can be a sustainable solution to treat wastewater and to recover resources such as nutrients, water and biomass from small municipalities and isolated dwellings. However, under certain conditions, the leakage of nutrients, especially of nitrate, can represent a limitation. The addition of two sustainable soil amendments, wo...
The use of surface water impacted by wastewater treatment plant (WWTP) effluents for crop irrigation is a form of unplanned water reuse. Natural attenuation processes can buffer contamination spreading. However, this practice can promote the exposure of crops to contaminants of emerging concern, such as pharmaceuticals, trace metals (TMs) and metal...

RESUMEN En las aguas superficiales localizadas aguas abajo de grandes ciudades se detectan frecuentemente fármacos y productos de transformación (PTs). La reutilización indirecta de este recurso en el riego de cultivos requiere estudiar la posible propagación de la contaminación desde la fuente al receptor. En la zona de estudio, situada aguas abaj...
The attenuation capacity of Emerging Organic Contaminants (EOCs) using an Intensive Vegetation Filter (IVF) has been evaluated. An Imhoff Tank pretreats the wastewater of an office building and its effluent is used to irrigate a VF. Water quality was monitored in the Imhoff Tank Effluent (ITE), the Infiltrated Water (IW) (90 cm depth) and the Groun...
The study reports the results of a 2-year research, which consisted in monitoring ketoprofen concentration in a vegetation filter that treats wastewater produced by an office building. Therefore, samples were collected from wastewater, infiltration water and groundwater. Data reveal a quite persistent behaviour of the anti-inflammatory with 55% of...
Vegetation filters (VFs), a type of land application system, are a robust technology based on natural treatment
mechanisms for the removal of wastewater contaminants. Their capacity to attenuate emerging
organic contaminants (EOCs) has not yet been evaluated. The present study reports the results of a 2-year
EOC monitoring carried out using a popla...
Water reuse for aquifer recharge could be an important route for the introduction of emerging organic contaminants (EOCs) into the environment. The installation of a Horizontal Permeable Reactive Barrier (H-PRB) could constitute a tertiary treatment process to remove EOCs from treated domestic wastewater prior to recharge activities. The sorption-d...
In countries like Spain, where water is a limited resource, reusing effluents from wastewater treatment plants may imply the introduction of incompletely eliminated pollutants into the environment. Therefore, this work identified the role of sorption and biodegradation in attenuating pharmaceutical compounds (acetaminophen, carbamazepine, caffeine,...
Sulfamethoxazole, a sulfonamide antibiotic, is worldwide used for human and veterinary applications. Its incomplete removal during conventional wastewater treatment leads to the occurrence of this compound in different water bodies. Water reuse for irrigation or artificial recharge may imply the infiltration of this compound through the unsaturated...
The objective of the present work is to evaluate the treatment capacity of the unsaturated zone (UZ) to remove contaminants from a wastewater effluent using a vegetation filter. The wastewater effluent originates from an office building and it is characterized by a high organic carbon and nitrogen load. Prior to its application over the vegetation...
Vegetation filters, a nature based wastewater purification technology, have been reported as a feasible solution for small municipalities and scattered populations with limited access to sewage networks. However even when such a technology is properly planned, the leaching of contaminants through the unsaturated zone may occur. The amendment of soi...
In the present work, the sorption of pharmaceutical and personal care products (PPCPs) (acetaminophen, atenolol, carbamazepine, caffeine, naproxen and sulphamethoxazole) onto the natural organic matter (NOM) and the inorganic surfaces of a natural sandy loam sediment was quantified separately. The quantification was based on the PPCP charge, their...
The performance of a vegetation filter using a short-rotation coppice of poplars was evaluated over a 3-year period in terms of pollutant removal capacity. The vegetation filter was designed for scattered and small populations with no storage facilities and a wastewater application constrained by the own production of effluent. Wastewater effluent...
