Treatment of pumping wells case study
Results from an Australian Trial Problem The pumping wells had accumulated fat and grease on their walls. With time septic conditions had set in giving rise to strong malodours and the local residents had started to complain about the smell. In addition acids produced under septic conditions were damaging the structural integrity of the pipes and pumps and increasing maintenance costs. Action ...

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 ...

Semi-analytical 3D solution for assessing radial collector well pumping impacts on groundwater–surface water interaction
We present a new semi-analytical flow and transport model for the simulation of 3D steady-state flow and particle movement between groundwater, a surface water body and a radial collector well in geometrically complex unconfined aquifers. This precise and grid-free Series Solution-analytic element method approach handles the irregular configurations of radial wells more efficiently than ...

Water Active: Borehole Management in Civil Engineering Projects
Groundwater wells are common to many civil engineering schemes and their operational performance can play a crucial role in the successful delivery of a project, whether used for construction dewatering, alternative water supplies for facilities or any other application , the well performance must be optimized and high levels of operational efficiency and service availability achieved. A ...

Bank filtration as managed surface-groundwater interaction
Riverbank Filtration (RBF) is a managed surface-groundwater interaction process where surface water is induced to flow to pumping wells installed on the banks of rivers and lakes. We present the surface-groundwater interaction issues at various geomorphologic settings, from the headwaters of a river to its confluence with the oceans/lakes. In each reach, the factors for the sustainable operation ...

Cleo Springs, Oklahoma - in-situ chemical oxidation case study
A gasoline spill occurred when a fuel tanker was forced off this curve in rural Oklahoma. Initial responders were unsuccessful in their effort to remove all of the contaminated soil. Cedar Creek Engineering was contracted to remediate the residual soil and groundwater contamination. Here a recovery well and reagent injection points are installed. The treatment process called for Fenton's reagent ...

DTI installs 3 blind horizontal remediation wells in cobble
The Issue An active retail gas station next to a wetland area has benzene and trimethylbenzene plumes in a water table aquifer containing sand, gravel and cobbles. Rock fragments and boulders several feet in diameter lie in the vadose zone, between the ground surface and the water table. Business at the gas station would slow down or stop for an extended period of time if a vertical air sparge ...

SCADA monitoring maximizes pump system performance - Case Study
The system tracks pump efficiency so repairs can be anticipated with timely, accurate and reliable information. Manually managing a water system can be difficult, especially with population growth and limited resources. Saving time and money are common challenges for utilities. Water system management was an ongoing concern for the city of Eureka, Mo., located approximately 28 miles southwest of ...

Numerical Evaluation of Effectiveness of Drainwells in Dewatering Overburden at Surface Coal Mines
Abstract: Typical sedimentary sequences overlying coal seams consist of interbedded sandstones, siltstones, shales, and rider coal seams. In many surface coal mine settings, these sediments are saturated; and prior dewatering of them is necessary for effective and economic mining, including the stacking of saturated spoils. Such sedimentary sections usually have a very low vertical hydraulic ...

High Efficiency Softening Process (HESP) for Frack Flowback - produced water treatment study for City of Grand Prairie, TX
Barnett Shale play in Texas, the natural gas economy According to Potter, the 5,500 wells currently pumping gas in the Barnett Shale play will ultimately generate on the order of $35 billion for their owners. As those companies pay taxes and wages, and as their employees and contractors in turn spend their money, there is an economic ripple effect, creating an overall value of about $100 ...
