Water Well Rehabilitation: A Practical Guide to Understanding Well Problems and Solutions / Edition 1

Well rehabilitation techniques have been the focus of major advancemen ts in recent times. Environmental engineers can keep pace with those c hanges with the book Water Well Rehabilitation. Written from a microb iological viewpoint, the text outlines proven solutions to production problems in all types of wells. That perspective frequently yields ne w ideas and concepts, contrary to prevalent thoughts in mainstream lit erature on the subject. This is especially true in discussion of iron related bacterial sources, and details concerning unsafe bacterial sam ples and the contamination of wells.
