Leaky faults provide important flow paths for fluids to move underground. It is often necessary to characterize such faults in engineering projects such as deep well injection of waste liquids, underground natural gas storage, and radioactive waste isolation. To provide this characterization, analytical solutions are presented for groundwater flow through saturated aquifer-fault-aquifer systems...

An analytical solution is derived to investigate the influence of leakage on tidal response in a coastal leaky confined aquifer system. The analytical solution developed here is more general than the traditional solution obtained by Ferris [1951], which can be regarded as a special case of the solution presented in this paper. This solution is based on a conceptual model under the assumption th...

The U.S. Court of Appeals for the Second Circuit has interpreted section 113(f)(3)(B) of the Comprehensive Environmental Response, Cleanup, and Liability Act, or CERCLA, to only allow a party to seek contribution for claims resolved under CERCLA itself, rather than claims resolved under a state statute. In Trinity Industries, Inc. v. Chicago Bridge & Iron Co., the U.S. Court of Appeals for the ...

Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for ...

Karst aquifers occur in a range of climatic and geologic settings. Nonetheless, they are commonly characterized by their vulnerability to water-quality impairment. Two karst aquifers, the Edwards aquifer in south-central Texas and the Upper Floridan aquifer in western Florida, were investigated to assess factors that control the movement of contaminants to public-supply wells (PSWs). The geoche...

The Nubian Sandstone complex in the western desert is a part of the major regional Nubian aquifer system comprising West Africa. The different rock strata deposited in localities forming the units of the aquifer system. Farafra Oasis lies in the northern part of the Dakhla basin. In its southern region, the Nubian Sandstone (deep aquifer) is overlained by Dakhla shale but in the central and nor...

Groundwater monitoring and water level predictions have been a challenging issue due to the complexity of groundwater movement. Simplified numerical simulation models used represent system; these however only provide conservative approximation system may not always capture local variations. Several other efforts such as coupling with hydrological using geostatistical methods are being practiced...

The Heritage Lottery funded project, What’s Your Trinity Story? documents the history of the Trinity Centre in Bristol from the 1960s to today. Trinity embodies and reflects the social and cultural changes that have taken place around it. Since its de-consecration in 1976, Trinity has passed through the hands of a number of groups and owners, whilst developing into a major music and community a...

Aquitards are capable of generating and preserving large amounts of chemicals. The release of the chemicals from the aquitards poses a potential contamination risk to groundwater that may be used as a drinking water source. This work aimed to identify the contribution of hydrogeochemical processes in the aquitards to groundwater hydrochemistry in the underlying confined basal aquifer by studyin...
