Wells producing less than 6 gallons per minute may require the use of larger storage tanks and lower capacity pumps. Pump The pump section furnishes information on the type of pump installed, either a submersible or jet pump in domestic wells, the capacity of the pump in gallons per minute, the depth at which the pump is set and the company that installed the pump. The pump setting is determined by the static water level and drawdown data gathered during the well test. The pump must be set below the pumping water level, which is calculated by subtracting the drawdown at a given test rate from the static water level. This section describes the earth materials encountered by the drilling contractor when your well was drilled.
Aquifers are geologic formations that are capable of storing and tranmitting ground water.
The geologic formation descriptions and well construction information can be used to identify the aquifer being used for water suppply and to evaluate the source of well problems .
