The well is installed, the surface completion is finished but the well is still not ready to sample.  Development is a critical step following construction of monitoring wells that is often short-changed or, sometimes, not implemented at all when new wells are installed at a site.  This can result in a detrimental impact on the ability of the new well to yield representative ground-water samples – from the perspective of ensuring adequate flow toward and into the well, volume of water available for sampling, and formation-quality ground-water samples.  This module debunks many of the myths and misunderstandings associated with well development.  Learn what types of development methods are available, which work well and which don’t work well, which methods should never be used in monitoring wells, and why some wells should not be developed.
