Biodegradation of Fuel Oxygenates in Northeastern United States Aquifers with an Analysis of Underground Storage Tank Leaks
… understanding of where, when and under what hydrogeological conditions MTBE biodegradation occurs is needed. To this end, the northeastern United States offers a wide range of lithologies to study. This study examines which subsurface conditions are most conducive to MTBE biodegradation.</p> …

Application of multi-scale assessment and modelling of landfill leachate migration: implications for risk-based contaminated land assessment, landfill remediation, and groundwater protection
… that do not account for the heterogeneous conditions found at landfill sites. Interpreting geophysical conditions between sampled points is a common practise. Given the complex and heterogeneous conditions at landfill sites, such methodology introduces uncertainty into data sets. Secondly, …

Tuzla City (BiH): an example of geohazard induced by salt extraction
… of 400-500 m. The mining operation changed the hydrogeological conditions enabling the downward flow of fresh water causing additional salt dissolution. This process induced severe ground subsidence during the last 60 years reaching up to 10 meters of sinking in the most affected area. Stress …

Stability of tunnels in water saturated shale under cyclic stresses: investigation on the coupling between mechanical and seepage characteristics
… in the laboratory. Considering the stress and hydrogeological conditions during tunnel excavation, the study systematically examined the damage characteristics of water-saturated shale under cyclic stress disturbances and its mechanical-seepage coupling properties. The effects of water …
