Contaminant remediation refers to the process of removing or reducing pollutants, toxins, or other harmful substances from the environment, such as soil, water, or air. This can include techniques such as physical removal, chemical treatment, or biological remediation to clean up contaminated sites and protect human health and the environment. Contaminant remediation research aims to develop more effective, efficient, and sustainable methods for cleaning up polluted sites and restoring them to a safe and healthy state. This area of study is important for addressing environmental contamination issues and ensuring the long-term sustainability of our natural resources.
