Compared to the other Polish peat tests, the determined k values were at the lower end of their hydraulic conductivity range. The analysed organic soil is not a typical aquifer. Despite very high porosities (~88%) and a high organic matter content (81.1–89.4%) which is favourable for ...

Formation or aquifer waters for example cannot be oversaturated within the reservoir where they have come to equilibrium with the surrounding reservoir rocks and hydrocarbon phases over geological timescales. Thus, predictions into the future need to account for any changes in this parameter (e.g., ...
That is, during the particular time interval, the accumulation or loss of solute in an aquifer media and the outgoing solute flux should be in agreement with the initial solute concentration entering the system. Many researchers have developed a variety of equations that account for one or the ...
21. A process for the treatment of ground water contaminated with perfluoroalkyl and polyfluoroalkyl substances, wherein a permeable reactive barrier comprising the adsorbent according to claim 1 is located in the path of an aquifer contaminated with perfluoroalkyl and polyfluoroalkyl substances. 22. ...
The first part of the book is dedicated to basic analytical relationships referring to pumping tests with constant discharge rate. Conceptual models include confined, unconfined, confined–unconfined, heterogeneous, fracture-porous aquifers, as well as leaky aquifers and multi-layer aquifer systems. Compl...
Moreover, high rates of erosion due to rapid uplift of the arc zones and subsequent transport of the eroded sediments to the downstream basins lead to the presence of As-bearing minerals in arc derived sediments in the aquifer matrix96,97. The reported As concentrations in various lith...
These corporations cut deals with local communities to extract vast amounts of water from aquifer or under ground water systems. They all show up with charts, figures, computers, smartphones, suits and ties and wave wand loads of money at the local government. ...
The aquifer, underground caverns made of high quality rocks, depleted natural gas storage caves and salt domes with storage capacities of 300,000 to 600,000 m3 are most commonly used for the compressed air storage. Storage in underground, high-pressure pipes (20--100 bar) has also been ...
reaches the saturated zone is influenced by various biotic and abiotic factors, such as the surface land cover, surface water to catchment connectivity, the porosity, and the geology of the unsaturated zone, as well as the distance of the land cover to the aquifer (groundwater table depth). ...
