Environmental remediation is the process of cleaning up and restoring polluted or contaminated sites to minimize or eliminate the negative impacts on the environment and human health. This can include activities such as soil and groundwater treatment, removal of hazardous waste, and restoration of ecosystems. Remediation techniques can vary depending on the type and extent of contamination, and may involve physical, chemical, or biological methods. The goal of environmental remediation is to reduce pollution levels, protect ecosystems, and improve the overall quality of the environment.
