AbstractThe modern water well contractor is a combination structural engineer, mechanic, geologist and sanitarian. Contractor's skills and accumulated knowledge should be assembled within an area and used as the basis for design and water well specifications. Engineering a water well should have the primary objective of obtaining an adequate supply of potable water, with equal importance placed upon the protection of the source of supply.The drilling of a test bore should be included in the design of every water well. A properly drilled and accurately logged test bore can determine exact design features and equipment requirements. In an area where formation samples may be deceiving and where a more accurate log is required, it is possible to contract for an electric log of the test bore. When it is essential to obtain truly representative samples in an uncontaminated form, core samples may be taken as the test bore is being drilled.Well drillers have the right in most places to procure water for the consumers in the quantities available, and along with this right, they have the obligation of preventing contamination or depletion of the source of supply. It is the well drilling contractor's position to either directly design his projects or consult with the designing agent, making recommendations that will enhance quality rather than convenience or economy.The water well driller should acquaint his customer with modern construction procedures and modern water well design just as he has become aware of building codes and architectural specifications in the construction of buildings and homes. Contractors must keep pace with the achievements of technical people associated with the water well industry by self‐education and incentive. The water well industry should be, and is, proud of its responsibility.The design and construction of a water well is no longer limited to the procurement of underground water, but also entails certain obligations on the part of the designer or contractor. Every industry, particularly those who produce consumer goods, have certain responsibilities, but none of their products are as absolutely essential to the existance of life or have a more important role in the social and economic welfare of mankind than the product of the water well drilling industry.No other group has more knowledge of the vast underground water resources or the importance of t
