Underground Injection Control

Safe drinking water is a necessity for our health and livelihood. The Underground Injection Control (UIC) program serves to protect the quality of Hawaii's underground sources of drinking water from chemical, physical, radioactive, and biological contamination that could originate from injection well activity.

Underground Injection Wells are wells used for injecting water or other fluids into a groundwater aquifer. The UIC program protects our underground drinking water sources by governing the location, construction, and operation of injection wells so that injected fluids do not migrate and pollute our drinking water. They also classify aquifers into those that are designated as underground sources of drinking water and those that are not.

The boundary between non-drinking water aquifers and underground sources of drinking water is generally referred to as the "UIC Line". Restrictions on injection wells differ, depending on whether the area is inland (mauka) or seaward (makai) of the UIC line (see link to UIC Map with UIC line below). Note that on the UIC Map below the areas below the UIC line are labeled with UIC-code "1". Areas above the UIC line in the map are labeled with UIC code "100".
