Human Health and Ecological Risk Assessment

Steer Environmental conducted a human health and ecological risk assessment to determine whether contaminants identified in soils (antimony, arsenic, cadmium, copper, and zinc) on this industrial property posed unacceptable risks to human health or the environment under current and assumed future land uses and conditions for environmental due diligence and to facilitate a potential sale of the property.

The human health assessment evaluated contaminant exposures by site workers, trespassers, construction workers and utility workers. Assuming continued public access restrictions, human health risks were determined to be less than the CSR risk-based standards and therefore remediation or active risk controls to protect human health at the site were not considered to be needed.

Assuming the continued absence of vegetation on-site, operable exposure pathways for ecological receptors were not identified and therefore remediation or active risk controls to protect the environment were not considered to be needed.
