Notes:
1.) Soilesni: Standard for the soil to indoor air pathway with exposure to a residential receptor.
2.) SoilsDCni: Standard for the direct contact pathway with exposure to a residential receptor.
3.) SoilsLeach: Standard for the soil leaching to growndwater with groundwater consumption pathway with exposure to
a residential receptor.
4.) A "-" or a "- -" means that a standard was not developed.
5.) A "*" means that a comparison was not possible.
6.) "AIR" means that the vapor intrusion standard associated with enclosed space (indoor air pathway) is lower than the
soil standard.
