Abstract
Most people who contract for groundwater drilling do not bother to check the actual yield of such wells and suffer serious damage as a result. The following information will indicate the importance of monitoring and the methods of doing so.
The present article summarizes the main ideas about the need to make a pumping test an integral and culminating part of constructing any well for groundwater exploitation. In the description of the methods and in the ideas themselves, it cannot be original in that it deals with basic and simple concepts that have been applied for many years in other countries where groundwater is the vital element for populations and industries. The English and German language literature describing pumping test methods for water abstraction generally abound. Generally, these publications are highly technical, and for reasons of language and insufficient scientific preparation, would be beyond the reach of most of our drillers and those interested in groundwater issues. That is why we believe that the ideas and methods presented here, in elementary form, have some novelty. We are certainly sure that there is an urgent need for their knowledge and application among us: the contractors of wells, whose number is increasing day by day in Colombia, must be informed of the result of their management when paying a high cost for the construction of a well. Knowledge of the country's groundwater resources and their conservation, which are essential factors of progress in all areas of agriculture, industry, and water supply, can only be achieved based on pumping tests.
