Understanding the fate and transport of PFAS in subsurface is essential for groundwater contaminated site management. Most international studies focused on homogeneous sands, while other hydrogeological settings are less well studied. In this contribution, we investigate impact different glacial geological typically found Northern Hemisphere, possibly containing fractures heterogeneities, leaching through unsaturated sediments.We have implemented a vertical cross-section model that simulates...
Interest in using contaminant mass discharge (CMD) for risk assessment of contaminated sites has increased over the years, as it accounts that is moving and posing a to water resources receptors. The most common investigation CMD involves transect multilevel wells; however, this an expensive undertaking, difficult place right position plume. Additionally, infrastructure at site needs be considered. To derive initial estimate allow prioritization further investigations remedial actions,...
Point sources with contaminants, such as chlorinated solvents, per- and polyfluoroalkyl substances (PFAS), or pesticides, are often located in low-permeability aquitards, where they can act long-term threaten underlying groundwater resources. We demonstrate the use of a 3D numerical model integrating comprehensive hydrogeological contamination data to determine contaminant mass discharge (CMD) from an aquitard into aquifer. A mature point source dissolved solvent clayey till is used example....
Abstract Field investigations were carried out to determine the occurrence of tetrachloroethene ( PCE ) dense nonaqueous phase liquid DNAPL ), source zone architecture and aquitard integrity at a 30‐ 50‐year old release site. The is located in clay till unit overlying limestone aquifer. was investigated through multiple‐lines‐of‐evidence approach using various characterization tools; most favorable combination tools for geophysical investigations, membrane interface probe, core subsampling...
Gold nanoparticles coated with amphiphilic block co-polymer PVP-VA are found to be extremely mobile in sand columns laboratory based experiments. The ultra-stability obtained by such surface modification is also shown diluting down a concentration of 62.5 ppb groundwater having other ions. Such low level detection particles achieved non-destructive simple UV-Vis spectroscopic technique equipped liquid wave guide capillary cell (LWCC) units. These results propose the possibility using...
