How deep should a drinking water well be?
Where you are in the District’s 18 counties determines how deep your well must be to get water. For instance, in central Florida, the Floridan aquifer is 100 to 200 feet beneath the land’s surface. In north-central Florida, the aquifer is close to the ground’s surface. In the northeastern and southeastern portions of the District, the top of the Floridan aquifer can be as much as 450 feet below land surface. Intermediate aquifers, where present, are generally found at depths less than 150 feet below land surface. Surficial aquifers are found closest to land surface and are generally less than 50 feet deep. Remember, if you construct a well during a high water level period and stop drilling when you reach water, the well may not be deep enough to produce during low water levels (dry periods), especially if inadequate pumping equipment has been installed.
