May 1992, OSWER Directive 9283.1-06. Groundwater pollution: Occurrence, detection, and remediation of In the past, it was thought that groundwater is protected from pollution by layers of rocks and soil that act as filters. Groundwater pollution remediation involves three remedial approaches: containment, i.e. For certain sites, monitored natural attenuation, which relies on natural processes that decrease or attenuate soil and groundwater contaminant concentrations, may be used to complement or as an alternative to pump-and-treat or other active technologies. Depending on site conditions and cleanup goals, response actions may include active treatment or less active approaches. April 2018, EPA 542-F-18-001. in those buildings could be threatened.
