||The well tag is typically a small (3 x 5 inch) metal plate attached
to the portion of well casing that protrudes from the ground.
Information on the well tag includes: well driller
registration number, installer/driller name, date completed, depth (feet),
casing depth (feet), diameter (inches), static water level & date measured,
and the yield (output) of the well in gallons per minute (gpm) or specific
Well drillers typically attach the tag to the casing with
