Removal of arsenic from a deep well by electrocoagulation in a continuous filter press reactor
We investigated arsenic removal from groundwater by electrocoagulation (EC) using aluminum as the sacrificial anode in a continuous filter press reactor. The groundwater was collected at a depth of 200 m in the plateau region, in Central Mexico, (As 134 μg L−1, Fe 0.3 mg L−1, Cd 0.7 mg L−1, Na 58 mg L−1, pH 6.8). The influence of current density (J) and mean ...

Inequitable allocation of deep community wells for reducing arsenic exposure in Bangladesh
Community wells that extend deeper than most private wells are crucial for reducing exposure to groundwater arsenic (As) in rural Bangladesh. This study evaluates the impact on access to safe drinking water of 915 such intermediate (90–150 m) and deep (>150 m) wells across a 180 km2 area where a total of 48,790 tubewells were tested with field kits in 2012–13. Half the shallow private ...

Quality assessment of deep-well recharge applications in the Netherlands
Artificial recharge of aquifers can be performed for various purposes and under varying hydrogeological conditions. We present an overview of deep-well recharge applications which have taken place in the Netherlands over the last two decades. We present the purpose of each application, the issues which had to be resolved, the preventive measures which were taken to improve performance and the ...

Experimental study of the effect of temperature on the flow behaviour of oil-based muds in Niger delta formation
The behaviour of the drilling fluids under high temperature is extremely important for drilling deep wells. Most commercial oil-base drilling fluid systems have limitations such as reduced rheology and filtration control if the fluid is exposed to higher temperature for prolonged periods of time. Formulating a drilling fluid system that can adequately withstand drilling in a high temperature ...

Effect of soil-use on deep groundwater quality in Southern Chile
This study evaluated the effects of farming activities on the quality of deep well water in Southern Chile. In this area, the use of fertilisers is becoming more widespread and the accumulation and poor management of cattle slurry and silage sub-products increases the risk of contamination. The study was carried out in the province of Osorno, where rainfall occurs all year round (maximum in ...

Study on method and mechanism of deep well circulation for the growth control of Microcystis in aquaculture pond
In order to control the growth of Microcystis in aquaculture ponds and reduce its adverse effect on water quality and aquaculture, a production-scale experiment of deep well circulation treatment was carried out in an aquaculture pond with water surface area of 63,000 m2 and water depth of 1.6–2.0 m. Compared with the control pond, the experiment pond had better water quality as indicated by ...

A Smelly Situation: Snuffing Out H2S in Water and Air
Untitled Document Summary: Dealing effectively with hydrogen sulfide (H2S) in groundwater presented a major challenge for coastal Indian River County, Fla. Stripping the odorous substance from the water was only half the solution; keeping the smell from drifting through the air in the neighborhood was the other half. Like most central Florida communities, Indian ...

Dewatering Crews Keep the Alameda Corridor Dry and Open for Business
Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...

Visualization of Transparent Exopolymer Particles (TEP) in various source waters.
Transparent Exopolymer Particles (TEP) have been implicated as an important factor in the development of aquatic biofilm on membranes and other surfaces. We have recorded TEP and associated bacteria from four different kinds of source water (coastal seawater, freshwater lake, secondary treated wastewater and saline, high sulfide content groundwater from a deep well) as visualized by light and ...

Griffin Dewatering pumps 15 million gallons of water from flood control project with 75 foot deep wells
On April 29 2011, Houston-based Griffin Dewatering Corp. began pumping 15 million gallons of water from the site. It also used 42 10-in.-dia, 75-ft-deep wells outside the dam perimeter to lower the groundwater table and relieve external hydraulic pressure. Griffin is working on several Corps projects in New Orleans, but Michael Lippard, Griffin senior project manager, says Seabrook is ...
