Underground Injection
Control (UIC) Program
Directions to KDHE and Visitor Parking
Information
The UIC Program at KDHE is administered by the
UIC Unit within the Geology Section. The purpose of the UIC Program
is to protect public health and safety, and the environment from
injection activities. Injection well activities include the disposal
of industrial waste into deep geologic formations, the solution
mining of salt formations and the shallow injection of a variety of
nonhazardous fluids below the land's surface.
The UIC program categorizes injection wells
into five classes of wells. These are:
- Class I: Wells used to inject
hazardous wastes or dispose of industrial and municipal fluids
beneath the lowermost formation containing, within one quarter
(1/4) mile of the well bore, a source of fresh or usable water.
- Class II: Wells used to inject
fluids associated with the production of oil and natural gas or
fluids/compounds used for enhanced hydrocarbon recovery. These
wells normally inject below the lower-most fresh or usable water
bearing zone except in cases where this zone is hydrocarbon
producing. These wells are regulated by the Kansas Corporation
Commission. The contact for the KCC is (316) 337-6197.
- Class III: Wells which inject
fluids for the extraction of minerals.
- Class IV: Wells which dispose of
hazardous or radioactive wastes into or above a fresh or usable
water bearing zone. Class IV wells are prohibited.
-
Class V:
A Class V
well is a system used to inject non-hazardous fluids
underground. Fluids are injected either into or above an
underground source of drinking water. This diverse group ranges
from simple shallow wells to complex experimental injection
technologies.
Most Class
V wells are "low-tech" and depend on gravity to drain fluids
directly below the land surface. Drywells, cesspools, and septic
system leach fields are examples of simple Class V wells.
Because their construction often provides little or no
pretreatment and these fluids are injected directly into or
above an underground source of drinking water, proper management
is important.
More
sophisticated Class V wells may rely on gravity or use pressure
systems for fluid injection. Some sophisticated systems include
advanced wastewater disposal systems used by industry,
experimental wells used to test new or unproven technologies,
and even systems used to inject and store water for later reuse.
