[1] The method of recession analysis proposed by Brutsaert and Nieber (1977) remains one of the few analytical tools for estimating aquifer hydraulic parameters at the field scale and beyond. In the method, the recession hydrograph is examined as dQ/dt = f(Q), where Q is aquifer discharge and f is an arbitrary function. The observed function f is parameterized through analytical solutions to th...

In the processes of carbon capture and storage, sulfur nitrogen oxides (SOx NOx) would be possibly injected with CO2 depending on origin CO2. The thermodynamic properties these gases in saline aquifer are poorly known. Solubility is one key parameter to implemented geochemical codes modelling long-term evolution after injection. solubility NO known only at atmospheric pressure. this study, wate...

Abstract The present work was carried out in the deltaic region of river Godavari coastal Andhra Pradesh southern India to evaluate status groundwater quality for irrigation. Groundwater is predominantly used these productive agricultural fields. Saline water intrusion fresh aquifers, which mainly due excess withdrawal groundwater, recorded study area. A total 80 samples were analyzed physical ...

Sequestration of carbon dioxide in geologic formations, both deep aquifers and depleted petroleum reservoirs, has the potential to signi...cantly reduce the atmospheric emissions of that greenhouse gas. Injection into a deep saline formation di¤ers from injection into a hydrocarbon reservoir in that there is no produced ‡uid from the aquifer and the hydrogeologic characterization of both the re...

The geological storage of CO2 coming from large industrial facilities has been studied in detail for the last several years as a solution against the greenhouse effect and climate change in a number of countries. It is considered as a complementary solution together with the research for the non pollutant or/and renewable energy sources. One of the available options is the injection of the supe...

A polyphasic approach based on cultivation and direct recovery of 16S rRNA gene sequences was utilized for microbial characterization of an aquifer contaminated with chlorinated ethenes. This work was conducted in order to support the evaluation of natural attenuation of chlorinated ethenes in groundwater at Area 6 at Dover Air Force Base (Dover, DE). Results from these studies demonstrated the...

Transport behaviors of unidentified flagellated protozoa (flagellates) and flagellate-sized carboxylated microspheres in sandy, organically contaminated aquifer sediments were investigated in a small-scale (1 to 4-m travel distance) natural-gradient tracer test on Cape Cod and in flow-through columns packed with sieved (0.5-to 1.0-mm grain size) aquifer sediments. The minute (average in situ ce...
