Monitoring Well Development—Why and How

Source

The objectives of monitoring well development are these: (a) to permit taking of sediment-free samples, (b) to allow water to flow freely into the well so representative samples can be taken rapidly, and (c) to remove all traces of the drilling fluid used in order to minimize any interference with the water quality.

Several development methods have been well documented as to their practicality and effectiveness in developing water supply wells. These methods are mechanical surging, overpumping, air lift, high-velocity water jetting, and several combinations of these methods. All of these methods can be used in monitoring well development but have limitations. Their limitations are usually related to the well diameter, restrictions on placing foreign materials in the well, low-permeability formations, and poor well intake design.

The methods and limitations are reviewed in this paper.
