"This manual is a guide for engineer personnel responsible for planning, designing, and drilling wells. This manual focuses on techniques and procedures for installing wells and includes expedient methods for digging shallow water, such as hand-dug wells. Engineer personnel assigned to well-drilling teams must have a basic understanding of groundwater principles and well-drilling mechanics and hydraulics to successfully install wells. A well driller enhances his skills primarily from experience in solving problems, overcoming obstacles in the field, and learning from failures. This manual reviews common experiences well drillers encounter in the field."-From the Preface.
