Article
A multiple linear regression (MLR) model was developed for the Osona region (1260km2, NE Spain) to determine aquifer vulnerability to nitrate pollution in groundwater. The MLR model was based on a data set of nitrate data from 57 private wells sampled in 2010. Up to 70 explanatory variables were screened to statistically identify the key parameters...
Article
Contamination from agricultural sources and, in particular, nitrate pollution, is one of the main concerns in groundwater management. However, this type of pollution entails the entrance of other substances into the aquifer, as well as it may promote other processes. In this study, we deal with hydrochemical and isotopic analysis of groundwater sam...

This study presents a meta-analysis of 12 experiments that quantify nitrate-N leaching losses from grazed pasture systems in alluvial sedimentary soils in Canterbury (New Zealand). Mean measured nitrate-N leached (kg N/ha × 100 mm drainage) losses were 2.7 when no urine was applied, 8.4 at the urine rate of 300 kg N/ha, 9.8 at 500 kg N/ha, 24.5 at...
Article
Non-point agricultural pollution is a major concern in groundwater management. To investigate nitrate input to the subsurface through groundwater recharge, thirteen natural springs were sampled. Discharge, electrical conductivity (EC), nitrate concentration, pH value and water temperature were monitored every two weeks from January 2010 till Februa...
Article
Nitrate pollution is one of the main concerns of groundwater management in most of the world's agricultural areas. In the Osona region of NE Spain, high concentrations of nitrates have been reported in wells. This study uses the occurrence of this pollutant in natural springs as an indicator of the sub-surface dynamics of the water cycle and shows...
Article
The fate and degradation of 28 multiple-class veterinary pharmaceuticals in an on-farm pig slurry treatment plant based on solid-liquid separation and a nitrification-denitrification (NDN) sequence batch reactor (SBR) were evaluated for the first time. The pharmaceuticals detected at the highest concentrations in raw pig slurries belonged to the gr...
Article
This study investigated, for the first time, the distribution and fate of 28 multiple-class veterinary pharmaceuticals and antibiotics (PhACs), and their corresponding antibiotic resistance genes (ARGs), in a full-scale on-farm livestock waste treatment plant. The plant relies on several technologies, including: anaerobic digestion (AD), solid-liqu...
Article
Despite the increasing public concern about the frequent occurrence of pharmaceuticals in the water bodies, their transport and fate are not yet well known; in particular in groundwater. In this laboratory study, batch experiments were conducted to investigate the sorption behaviour of selected pharmaceuticals. The choice of compounds was motivated...
Article
Urban areas have been identified as one of the key challenges to tackle in the next decades. Most of the environmental impacts associated to urban contexts are linked to an unsustainable use of resources basically due to urban planning and society’s consumption behaviour. Currently, the paradigm of sustainable cities brought out in the past years s...

Urban areas have been identified as one of the key challenges to tackle in the next decades. Most of the environmental impacts associated to urban contexts are linked to an unsustainable use of resources basically due to urban planning and society’s consumption behaviour. Currently, the paradigm of sustainable cities brought out in the past years...
Article
The fate and transport of 34 veterinary pharmaceuticals (PhACs) is investigated in swine slurry and dairy cattle manure-amended agricultural soils, from an experimental field site, by using both analytical and modelled data. Potential differences on PhACs fate, attributed to the application of distinct swine slurry fractions (total, solid, and liqu...
Article
Les polluants émergents (EOCs, et parmi eux des antibiotiques vétérinaires) par rapport à l'utilisation de fumier dans les activités agricoles sont de grande préoccupation sur la qualité des eaux. Ils sont ainsi responsables des changements dans les communautés microbiologiques existants dans les aquifères qui, à son tour, peuvent supposer un risqu...

Antibiotics are an increasing focus of interest due to their high detection frequency in the environment. However, their presence in water bodies is not regulated by environmental policies. This field study investigates, for the first time, the occurrence, behavior and fate of a selection of 53 antibiotics, including up to 10 chemical groups, in an...

In agreement with the objectives of the JPI Water Call, the aim of the PERSIST project is to investigate the fate of Emerging Organic Contaminants (EOCs), and resistant microbial communities in a surface water - groundwater continuum in alluvial basins. Field observations are complemented with columns and batch experiments to characterize transport processes. The Consortium groups researchers from the University of Nîmes (CHROME EA7352) , Catalan Institute of Water Research (ICRA) and the Helmholtz Zentrum of Munich (Intitute of Groundwater Ecology).
