This is the response to a DEWPoint helpdesk enquiry that asked for guidance on the minimum specification for the design of an effective apron slab design for use at the top of a borehole equipped with a hand pump. The report starts by defining what an apron slab is and what its main pu...
collected in desk studies and field reconnaissance; look at general aspects of planning investigations including what influences the selection of methods of investigation; discuss methods of intrusive investigation (including excavations and boreholes) and the methods of geophysics used for...
A large number of point discrete ground water samples were required for a UK research project aimed at quantifying natural attenuation processes in ground water contaminated by a former coal carbonization plant. Based on experience from a previous project to develop novel level accurate sampling ...
An approach to characterization of multilayer aquifer systems using open well borehole dilution is described. The approach involves measuring observation w... LJ West,NE Odling - 《Groundwater》 被引量: 51发表: 2007年 Educating Tomorrow's Scientists: IT as a tool, not an educator The use of...

Field testing of the design in an existing borehole in the unconfined sandstone aquifer underlying the city of Nottingham (UK) demonstrates the efficacy of the design in fissured bedrock as significant hydrochemical variations are observed over a few metres in depth. The availability and low cost ...

The focus then shifts to a comparison between manual drilling and other groundwater access methods (i.e., excavated wells and mechanized boreholes). Finally, the successes and challenges faced by the manual drilling sector are appraised in the context of the need to achieve universal water ...
