Refers to the process of treating contaminated sites or areas by applying various techniques directly to
the location of the contamination, without removing the contaminated material from the site. This
approach is often sustainable and more cost-effective and efficient than traditional remediation
methods, as it eliminates the need for transportation and disposal of contaminated materials. In-situ
remediation techniques can include physical, chemical, or biological methods that are applied to the
soil, groundwater, or other affected media to reduce or eliminate the concentration of contaminants.
The goal of in-situ remediation is to restore the site to a condition that is safe for human health and the
environment.
