(English) Managed Aquifer Recharge (MAR) is a key strategy to increase freshwater resources in many regions facing water scarcity. The success of MAR facility implies both technical (water quality and quantity as main examples) non-technical aspects (legislation, funds, taxes, citizen perception, etc.). Therefore, the aim this thesis improve management do so, 1) an assessment general kind facilities 2) addition innovative procedure based on numerical modelling decrease contaminants input were needed. Specifically, case contaminants, reactive barrier was selected option its efficiency tested order see reduction nutrients pollutants emerging organic (EOCs). First, risk done for set across Mediterranean region. Those risks related different recharge. In thesis, definition quantification has been performed by means “fault trees” probabilistic (PRA). After that, we have applied methodology six managed aquifer recharge sites located Basin. probabilities basic events defined expert criteria, knowledge managers facilities. From conclude that all sites, much or even more important than aspects. On second place, possibility injecting lower (wastewater) letting biogeochemical reactions take place enhance explored. Here, present fate (C, N) system laboratory columns mimic (Modrzynski et al., 2021) included formed mixture proportions sand compost, supplied with treated wastewater. An integrated conceptual model involving dynamics biomass (auto heterotrophic) developed, then columns. developed allowed discriminate processes govern relation compost enhancing long-term nutrient degradation yet hindering hydraulic parameters affect infiltration rates. third following nutrients, dynamic EOCs studied. sorption biodegradation each individual compound are influenced overall geochemical signature sediment, reduction-oxidation dynamics. models involve two EOC biodegradation, span from them being considered either disconnected fully connected evolution major nutrients. used interpret concentrations five experiments 2021). coupled previous focused carbon nitrogen cycles validated. Our results demonstrate best reproduction data paracetamol sulfamethoxazole achieved when transport model. shows initial promise column barriers can be useful tool scenario. Finally wants offer big picture possibilities (using wastewater). This provided insight which issues find themselves during their operation. It also demonstrated potentiality reduce systems dynamics, therefore implying possible usage wastewater valuable resource rather waste.

Abstract Diclofenac (DCF) is a nonsteroidal anti-inflammatory drug commonly used in health care, livestock, and pharmaceuticals widely detected surface water environments globally. Here, we reviewed the occurrence characteristics, migration pathways, aquatic toxicity of DCF environments. Asian African populations are exposed to high concentrations (> 8,000 ng L−1). Wastewater discharge, industrial pollution primary factors influencing concentration distribution DCF. can cause acute toxicity, oxidative stress, other toxic effects on organisms. We focused China analyzed ecological risks found low risk south north, as well during rainy season dry season. Finally, discuss removal methods for propose potential metal-organic frameworks new material replace conventional removal. This study comprehensively reveals status it poses environments, providing reference environmental management

Abstract We present a methodology to quantify the impact of model structure and parametric uncertainty on formulations targeting biotransformation processes Emerging Contaminants in subsurface water resources. The study is motivated by recognizing that modeling bio‐mediated reactions recalcitrant compounds soil aquifers plagued uncertainty. At same time, process‐based models often require parameterization complex physico‐chemical processes, situation which exacerbated paucity direct observations. Thus, assessment formulation tools capable balance complexity reliability key challenge. strategy proposed here aims at pairing applying suite quantitative starting from prior diagnosis multiple sources leading parameter estimation selection presence limited number illustrated through application multi‐step, reactive scenario involving pharmaceutical diclofenac (DCF) groundwater. Our framework includes four plausible models. These are obtained successive simplifications recently developed highly model.

Contamination of groundwater with pharmaceutical active compounds (PhACs) increased over the last decades. Potential pathways PhACs to include techniques such as irrigation, managed aquifer recharge, or bank filtration well natural processes losing streams PhACs-loaded source waters. Usually, these systems are characterized by redox-active zones, where microorganisms grow and become immobilized formation biofilms, structures that colonize pore space decrease infiltration capacities, a phenomenon known bioclogging. The goal this work is gain deeper understanding influence soil biofilms on hydraulic conductivity reduction fate in subsurface. For purpose, we selected three different physicochemical properties (carbamazepine, diclofenac, metoprolol) performed batch column experiments using soil, it organic matter removed, under biological conditions. We observed enhanced sorption biodegradation for all system higher activity. Bioclogging was more prevalent absence matter. Our results differ from works artificial porous media thus reveal importance utilizing soils studies designed assess role bioclogging soils.
