Classifications of Injection Wells
Class
Description
c. Subsidence control wells (not used for
V
the purpose of oil or natural gas pro-
duction) used to inject fluids into a
zone that does not produce oil or gas to
reduce or eliminate subsidence associated
with the overdraft of fresh water.
d. Connector wells used to connect two
aquifers to allow interchange of water
between those aquifers.
Group 3
a. Wells that are part of domestic waste
treatment systems.
b. Swimming pool drainage wells.
c. Devices receiving wastes, which have an
open bottom and sometimes have perforated
sides. This rule does not apply to
single-family residential waste disposal
systems.
d. Wells used to inject spent brine into the
same formation from which it was with-
drawn after extraction of halogens or
their salts.
e. Injection wells used in experimental
technologies.
Group 4
a. Dry wells used to inject wastes into a
subsurface formation.
b. Sand backfill wells used to inject a
mixture of water and sand, tailings, or
other solids into mined-out portions of
subsurface mines.
c. Wells other than Class IV used to inject
radioactive waste, provided the con-
centrations of the waste do not exceed
drinking water standards contained in
Chapter 62-550, F.A.C.
