AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Groundwater is essential for human activities and is sometimes referred to as a non-renewable resource in the same way as oil and gas. During the past century, precious groundwater reserves worldwide have been threatened by anthropogenic release of chemica ...
Chlorinated ethenes (CEs), such as perchloroethene (PCE) and trichloroethene (TCE), are one of the most common class of groundwater contaminants. Aquifers are considered nowadays as dynamic ecosystems, showing multiple interactions between the physical, ch ...
Most peri-alpine shallow aquifers fed by rivers are oxic and the drinking water derived by riverbank filtration is generally of excellent quality. However, observations during past heat waves suggest that water quality may be affected by climate change due ...
Organic matter (OM) is a key component of soils but information on its chemistry and behavior in soils is still incomplete. Numerous methods are commonly used to characterize and monitor OM dynamics, but only a few include the qualities required to become ...
Dissolved organic matter (DOM) can act as a photosensitizer and an inhibitor in the phototransformation of several nitrogen-containing organic contaminants in surface waters. The present study was performed to select a probe molecule that is suitable to me ...
A numerical investigation is presented that demonstrates the influence of tides and waves on the transport and transformation of nutrients (NO3-; NH4+; PO43-) in a homogeneous unconfined nearshore aquifer and subsequent fluxes to the sea. Simulations of an ...
Reductive biostimulation is currently being explored as a possible remediation strategy for U-contaminated groundwater, and is being investigated at a field site in Rifle, CO, USA. The long-term stability of the resulting U(IV) phases is a key component of ...
The landfill of Colliare is situated on the left bank of the river « la Venoge », at the place of a former gravel pit in the municipality of Penthaz. It was exploited until 1995 and many different wastes were deposited in it, such as incineration slag of h ...
The peatland carbon store is threatened by climate change and is expected to provide positive feedback on air temperature. Most studies indicate that enhanced temperature and microbial activities result in a rise of dissolved organic carbon (DOC) as a cons ...
The potential application of monitored natural attenuation (MNA) as a remedy for ground water contaminated with arsenic (As) is examined for a subset of contaminated sites, specifically those where naturally occurring As has been mobilized due to localized ...
