Which disposal method involves injecting liquid waste into the ground through disposal wells?

Explanation:
Injecting liquid waste into the ground through disposal wells is a deep underground disposal approach for hazardous liquids. The goal is to place waste far below the surface in geological formations that act as barriers, isolating it from groundwater and the environment. That specific aim—isolating hazardous liquid waste by subsurface injection—defines this as liquid hazardous waste disposal. Other options describe wastewater treatment and surface discharge (municipal sewage), storage in surface reservoirs (reservoirs), or contamination from materials in pipes (lead pipe leaching), none of which involve injecting waste underground.
