Landfill Leachate Sources and Treatment Options

by Agru America, Inc.  (Jun. 4, 2015)

What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation ...

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 ...

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 ...

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 ...
