Legal Issues Impacting the Water Well Industry (1 Hour) The well should be at least five (5) feet away from any overhanging rooftops or power lines. These contours generally are more highly constrained than those for the unconsolidated sedimentary aquifer, especially in the central part of the area, due to the greater availability of well data for this aquifer. A two-dimensional map representation of the principal aquifers of the Nation is shown below.
