Some activities may cause releases of chemicals to the environment that can adversely affect humans, plants and animals. Remediation must occur to ensure that these potential negative impacts do not take place. Alberta Environment and Parks develops assessment and monitoring tools for the physical clean-up of areas contaminated by past activities.

The department's framework for managing contaminated sites is designed to encourage pollution prevention, health protection and productive land use.

Remediation may include: source removal, physical removal of contaminated groundwater and/or soil, natural attenuation, degradation by micro-organisms or neutralization with chemicals that react with the contaminants to form benign substances.

Certain types of industrial facilities require operating approvals from the department. When a facility reaches the end of its operating life, its approval is amended to become a decommissioning and reclamation approval. This amended approval specifies what must be done, including dismantling, decommissioning and land reclamation, so that any potential impacts on the environment are resolved before the facility is deemed "reclaimed".

Remediation is also required before the department will issue a reclamation certificate for an upstream oil and gas site. Upstream sites include well sites, pipelines and batteries.
