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 managers have often to face regional degradation of the quality of the groundwater under the pressure of diffuse pollution. One of the most problematic and widespread contaminant is certainly nitrate whose concentrations are found in many aquif ...
Numerous industries have been using chloroethenes (CEs), mainly tetrachloroethene and trichloroethene, as non-flammable solvents since the beginning of the 20th century. Massive usage, along with careless handling and storage, made CEs one of the most abun ...
The fate and transport of As was examined at an industrial site where soil- and groundwater contamination are derived from the application of As2O3 as a herbicide. Application of arsenical herbicides was discontinued in the 1970s and soils in the source ar ...
Reaction of anilines, primary and secondary aliph. amines with cyclopropylboronic acid in dichloroethane in the presence of Cu(OAc)2 (1 equiv.), 2,2'-bipyridine (1 equiv.) and sodium carbonate or sodium bicarbonate (2 equiv.) under air atm. afforded the co ...
Recent studies on the complex 3D geometry of large cave systems around the World allowed us to get statistical evidence of the inception horizon hypothesis. It clearly confirmed the idea that the development of karst conduits under phreatic conditions is s ...
Numerous industries have been using chlorinated ethenes (CEs), mainly tetrachlorethene and trichloroethene, as non-flammable solvents since the beginning of the 20th century. Massive usage, along with careless handling and storage, made CEs one of the most ...
Modeling groundwater flow and contaminant transport in industrialized and urbanized alluvial plains is challenging because of the dynamic nature of the strongly interacting river – groundwater system and the scarcity of data. An original combined regional ...
The organic interprismatic layers of the mollusc Pinctada margaritifera are Studied using a variety of highly spatially-resolved techniques to establish their composition and structure. Our results show that both the interlamellar sheets of the nacre and i ...
Rare earth elements (REE) were determined in 39 groundwater samples collected at 14 sites under low- and high-flow conditions. Water samples derived from aquifers hosted in crystalline, molasse, flysch, carbonate and evaporite rocks located in Western Swit ...
Land use changes and the intensification of agriculture since the 1950s have resulted in a deterioration of groundwater quality in many European countries. For the protection of groundwater quality, it is necessary to (1) assess the current groundwater qua ...
