Site Characterization and Conceptual Site Model
Site characterization and development of a conceptual site model provides information about the full extent and location of the contamination; the nature and characteristics of the contamination; the characteristics of the site that influence contaminant migration, including the potential for biodegradation of petroleum hydrocarbons; and the locations of receptors. Information derived from the conceptual site model helps ensure that sources, pathways, and receptors throughout the site are considered.
Lateral Inclusion Zone
The lateral inclusion zone is the area surrounding a contaminant mass through which petroleum vapors may travel, intrude into buildings, and potentially pose a threat to human health and the environment. Buildings directly above contamination sources, whether as mobile LNAPL, residual LNAPL, or petroleum hydrocarbons dissolved in groundwater, are considered within the lateral inclusion zone.
