TB-022 Deep Well Injection

Deep well injection is a method of disposing of liquid waste into geologic formations to prevent contamination of potable water sources. The practice began in the 1930s and is regulated by the EPA under the Safe Drinking Water Act. There are six classes of injection wells based on their use, including disposal of hazardous waste, oil and gas fluids, and CO2 sequestration. Filtration is crucial for preserving well integrity and preventing fouling, with filtration requirements varying based on the injection zone characteristics. Identifying deep well injection sites can be challenging due to negative perceptions, but regulation and oversight are managed at both federal and state levels.
