The Southeast District Underground Injection Control Section can be reached by contacting 561-681-6600.


Eighty percent of all underground injection wells are located in Southeast Florida.  The FDEP's Underground Injection Control (UIC) Program consists of a team of geologists and engineers dedicated to protecting Florida's underground sources of drinking water (USDW) while maintaining the lawful option of disposal of appropriately treated fluids via underground injection wells.  A USDW is defined as an aquifer that contains a total dissolved solids concentration of less than 10,000 milligrams per liter.

The UIC Program is also dedicated to preventing the degradation of the quality of other aquifers adjacent to the injection zone.  Subsurface injection, the practice of emplacing fluids in a permeable underground aquifer by gravity flow or under pressure through an injection well, is one of a variety of wastewater disposal or reuse methods used in Florida.


The Five Classes of Injection Wells

  • Class I: Wells used to inject hazardous waste (new hazardous waste wells were banned in 1983), nonhazardous waste or municipal waste below the lowest USDW.

  • Class II: Wells used to inject fluids associated with the production of oil and natural gas, or fluids used to enhance hydrocarbon recovery.

  • Class III: Wells which inject fluids for extraction of minerals (none are in Florida).

  • Class IV: Wells or septic systems which are used to dispose of hazardous or radioactive wastes into or above a USDW.  This is banned in Florida.

  • Class V: Wells not included in the other well classes which generally inject nonhazardous fluid into or above a USDW.


The UIC Section is another permitting and compliance enforcement activity that the Environmental Protection Agency (EPA) has delegated to the FDEP.  For details on types of wells, visit the FDEP's main UIC Web site.

A permit for a UIC well requires that reasonable assurances are provided to protect the ground waters of the state as required under Florida Administrative Code (F.A.C.).
