We have all been told at some point in our life that good things come to those who wait. In well rehabilitation projects, chemical contact time is one part of a successful program. This is an area that I always get questioned on when talking with contractors looking at a well rehabilitation project. When products are not given sufficient time to work, the results can be disappointing for the project. There are several aspects to consider when putting together an estimate and plan for the well owner. The ultimate decision is to rehabilitate their well or drill a new well.
