The study of water sources used by the population of Ndian for drinking with the exception of the Ekondo Titi beach was carried out by investigating 51 water sources. Due to the lack of pipe borne water in this area, the population is compelled to consume water from unprotected shallow aquifers and surface water sources, there by exposing the population to infections form of water borne diseases. In this perspective, the present study was aimed to check the suitability of these water sources...

Indoor plants are automatically watered by the Aqua Trends watering system. System draws water from building outlets or from pump/reservoir module and distributes it to the plants via a network of tubes and adjustable nozzles. Key element of system is electronic controller programmed to dispense water according to the needs of various plants in an installation. Adjustable nozzle meters out exactly right amount of water at proper time to the plant it's serving. More than 100 Aqua/Trends systems...

Fresh groundwater in an island aquifer is an extremely important resource that is highly vulnerable to variations in natural weather cycles and climate change effects. On small islands, precipitation creates subsurface freshwater lenses that float on top of coalesced saltwater that has intruded from the surrounding seawater. The volume and shape of these highly vulnerable freshwater lenses depend on the size and shape of the island, underlying geology, and the rate and duration of groundwater...

Nonconventional water resources have been allocated by the government of Jordan to provide cooling water for the first Jordanian Nuclear Power Plant (NPP). These resources included reclaimed wastewater from AsSamra Wastewater Treatment Plant, and groundwater from the deep aquifers (more than a 1000 meter depth) in the vicinity of the NPP site. This decision generated great attention and its soundness has been questioned by many skeptics of the nuclear program in Jordan. To address these...

This report documents a computer program, the Subsidence and Aquifer-System Compaction (SUB) Package, to simulate aquifer-system compaction and land subsidence using the U.S. Geological Survey modular finite-difference ground-water flow model, MODFLOW-2000. The SUB Package simulates elastic (recoverable) compaction and expansion, and inelastic (permanent) compaction of compressible fine-grained beds (interbeds) within the aquifers. The deformation of the interbeds is caused by head or...

This project was a Workshop, held in San Antonio, Texas, May 3-5, 2007. The objective of the workshop was to assess the current state of knowledge of karst aquifers, caves, and the broader scientific values that could be derived from their study. The term karst is used to describe landscapes underlain by soluble rocks and as a result has developed landforms such as sinkholes, sinking streams, and caves. Such landscapes have special environmental hazards such as contaminated water supplies,...

The objectives of task 37 are to locate, examine, and properly close wells on RMA that may be allowing, or could potentially allow, migration of contamination from upper aquifers to deep aquifers. The technical approach was structured in such a way that unused were closed on a prioritized basis according to potential to adversely impact deep aquifers. The study area limited to those areas of RMA that are within or down-gradient of potential sources of contamination. A total of 39 wells were...

Contaminant redistributive effects in wells are nearly always present. Complete mixing appears to be very common; however, it is not universal. There is a continual balance between inflowing contaminant stratification (where present) and factors driving in-well mixing. Findings here imply common and very small drivers are responsible for slow but vigorous mixing relative to the residence time of water flowing through a typical well screen. Therefore, a tendency toward homogenization is...

The purpose of this investigation is to evaluate the hydrogeologic characteristics of the bedrock aquifers in the basin, and the origin, movement, quantity, availability, and use of the ground water. The chemical quality of the water and its suitability for different uses are also evaluated. Consideration is given to the present and probable future distribution of deep wells in the Denver Basin, and to the possible effects of long-term withdrawals from the various aquifers.

DGCHANGE v1.0 estimates dissolved contaminant concentration reductions with time in nearfield monitoring wells down-gradient of permeable treatment barriers (PTBs). In this spreadsheet-based tool the aquifer is represented as a series of horizontal layers and the user enters layer-specific aquifer characteristics. The output is presented graphically in three main formats: (a) a cross-section snapshot of dissolved concentrations along the groundwater flow path at some user-specified time, (b) a...

The primary objective of this project was to test the performance of two different reactive media in the same aquifer. To satisfy this objective, Battelle designed, constructed, and monitored a pilot-scale permeable reactive barrier (PRB) in Area 5 at Dover Air Force Base, DE. The PRB was installed in December 1997 to treat a perchloroethylene plume and was monitored over 18 months of operation. The PRB is a funnel-and-gate system with two gates. Both gates contain granular iron as the reactive...

Dense Nonaqueous Phase Liquids [DNAPLs] are prevalent at a large number of sites throughout the world. The variable release history and geologic heterogeneity make the spatial distribution of DNAPLs in the source zone complex. This causes difficulties in cleanup and can contribute to long-term groundwater contamination for decades to centuries. Therefore, the spatial distribution, mass, and composition of DNAPLs present in the source zone need to be characterized in sufficient detail so that...

In February 2020, Pluto Press published Hidden San Francisco: A Guide to Lost Landscapes, Unsung Heroes, and Radical Histories by Chris Carlsson. This video looks at the long debate over whether there was a fresh water lake in the Mission, confused with the tidal lagoon called Laguna Dolores. It is the 15th and final of just over a dozen short videos of "stops" (there are 85 "stops" in four themed chapters, and an additional 44 "stops" in five walking tours in the...

Hydrogen biosparging of aquifers contaminated with chlorinated solvents is promising as a method to enhance in situ microbial dechlorination. The major problem is the inability to distribute hydrogen throughout the contaminated interval such that complete dechlorination can occur. Foam is a dispersion of gas in water that is stabilized from coalescence by the presence of a low concentration of surfactants. A promising method to greatly extend the horizontal migration of hydrogen in the...
