Abstract
Assesses, through a streamlined risk assessment process, potential human health and ecological risks associated with mining-related contamination at the Monumental, Cap Martin, Sheridan, Tillicum, and Central Mines (collectively called Granite Creek Mines). Arsenic and lead were identified as contaminants with carcinogenic risk predicted from exposure to arsenic-impacted surface water and soil/wasterock. Soil and wasterock threaten ecological impacts for primary plants and terrestrial invertebrates, and surface and pore water similarly pose a threat to aquatic life and wildlife. An Engineering Evaluation/Cost Analysis (EECA) is recommended, along with a data gap investigation.
