Borehole Diagnostics Toolkit

A borehole is a structure that is susceptible to physical, chemical and biological processes that may influence its life span, yield and water quality. The above factors depend on quality of borehole construction, the way it is operated and geological conditions or aquifer characteristics. Deterioration of a borehole may lead to some serious contaminations of water harmful for human use and eventually it being abandoned, leading to costly measures to develop alternative water sources for communities. Borehole diagnosis and rehabilitation is often a cheaper alternative to new borehole drilling.

Borehole diagnosis entails using visual enhancement tools like down-the-hole camera, depth water sampling probe and data logging probe tools to infer the physical, chemical, geological and aquifer characteristics that may be influencing the poor performance of a borehole. This inference combined with water quality analysis and borehole capacity pumping tests help to understand the cause of borehole deterioration and determine the relevance of a corrective measure.
