As shown in the Remedial Investigation Reports, benzene is present in groundwater but is less extensive in soil. While concentrations of benzene in soil and groundwater exceed the statewide health standards in sampling locations, the concentrations in soil and groundwater have not been shown to emit high levels of benzene into the atmosphere. Many samples have already been collected to evaluate benzene in air, and part of the future risk assessment and cleanup plan activities includes further vapor intrusion assessment, which looks at potential for migration of vapors from soil and groundwater.
