Optimal groundwater contamination monitoring using pumping wells

by IWA Publishing  (Aug. 1, 2010)

This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution ...

Estimating Future Impacts of Groundwater Contamination on Water Supply Wells

by Solinst Canada Ltd.  (Feb. 1, 2001)

In the following sections, we provide discussion and information to supplement the Feature Article. This material could not be included in the article itself due to space limitations of the printed ...

Small Systems Helpdesk -- Profiling Groundwater Wells - an Alternative to Treatment

by American Water Works Association (AWWA)  (Jun. 1, 2004)

This article discusses how data from a groundwater well´s profile can be used to modify the well so that raw water with undesireable chemical qualities is prevented from entering the well. A case study is presented of the town of Goodland, Indiana where the town´s raw water had concentrations of sulfur that caused taste, odor, and other problems ...

Gimmicks & Gadgets - Well/Float Gauge Used to Monitor the Depth to Shallow Groundwater

by American Water Works Association (AWWA)  (Dec. 1, 1988)

A well/float gauge, constructed of PVC pipe, has been developed to enable crop growers to directly read and constantly monitor shallow water table ...

Groundwater exploration

by Advanced Geosciences, Inc.  (Jan. 1, 2005)

This is a collection of various cases where the 2D resistivity imaging method pioneered by Advanced Geosciences Inc have been successfully ...

Well-Field Management

by American Water Works Association (AWWA)  (Mar. 1, 1978)

A well-field management program recognizes that a groundwater supply comprises two components, the aquifer, or water-bearing media, and the well. Only by monitoring each component and evaluating their interplay is effective groundwater supply management possible. If a groundwater management program is to work, it must satisfy two objectives. It ...

Well Clogging by Particles in Dutch Well Fields

by American Water Works Association (AWWA)  (Aug. 1, 2003)

For the water supply company Hydron South Holland in the Netherlands, clogged wells constituted a significant problem that lowered production capacity of the well field, disrupted the purification process at the treatment plant, and decreased overall revenues. This study was undertaken to develop a better understanding of the clogging process, the ...

Restoring Well Yield in the Netherlands

by American Water Works Association (AWWA)  (Oct. 1, 1984)

This article summarizes results of research on the rehabilitation of clogged extraction wells in the Netherlands by KIWA, the Netherlands Waterworks Testing and Research Institute. Types of well clogging identified include clogging by accumulation of iron oxides and biomass, clogging caused by anaerobic geomicrobiological processes, and accidental ...

Concepts of Well Cleaning

by American Water Works Association (AWWA)  (May 1, 1988)

Cleaning wells to restore or improve production requires an evaluation of the probable causes of clogging, which includes a chemical analysis of the groundwater and a mechanical analysis of subsurface soils. Once the probable cause or causes of clogging are determined, the most appropriate treatment can be prescribed. The authors discuss the ...

Rural Boreholes and Wells in Africa

by American Water Works Association (AWWA)  (Aug. 1, 2003)

Africa´s unmet needs in water supply are enormous and widespread, especially in rural settings. This article looks at a basic type of water supply: low-yielding point sources tapping groundwater through boreholes and hand-dug wells. Data were obtained from three projects in a high-rainfall nation in West Africa and one project in a country in the ...
