How was the baseline risk assessment (BRA) performed for the NFSS?
• The NFSS baseline human health risk assessment was conducted consistent with CERCLA, USACE Guidance (EM 200-1-4), EPA guidance (Risk Assessment Guidance for Superfund), and used industry-accepted computer modeling software (RESRAD). All environmental media (surficial and deeper soils down to ten feet, surface water and sediment, groundwater) as well as pipeline and underground utility contents were evaluated. The evaluation included all chemical and radionuclides detected on site (and on the adjacent National Grid power right-of-way) above background concentrations. • A broad range of receptors were evaluated to encompass every possible current and future exposure and land-use scenario: • Current: Maintenance workers, trespassers (adult and adolescent), • Future: Trespassers (adult and adolescent), maintenance worker, construction worker, industrial worker, residential (adult and child) and subsistence farming (adult and child) • Exposure pathways evaluated included dermal absorption
