Well rehabilitation techniques have been the focus of major advancements in recent times. Environmental engineers can keep pace with those changes with the book Water Well Rehabilitation.
Written from a microbiological viewpoint, the text outlines proven solutions to production problems in all types of wells.
That perspective frequently yields new ideas and concepts, contrary to prevalent thoughts in mainstream literature on the subject. This is especially true in discussion of iron related bacterial sources, and details concerning unsafe bacterial samples and the contamination of wells.
