| dc.description.abstract | Documents Site Inspection performed by EA Engineering at five Granite Creek Mines: Monumental, Cap Martin, Sheridan, Tillicum, and Central. The objectives were to access the immediate or potential threat posed by wastes at the site to human health and the environment, and to collect information to support a CERCLA decision, including background research and file review; onsite and offsite reconnaisance; and collection and analysis of soil, waste, surface water, pore water, sediment, plant tissue, and benthic macroinvertebrate samples. Based on the elevated concentrations of metals detected in onsite soil and waste rock samples at all five mine sites, as well as onsite surface water samples collected at the Monumental Mine, an Engineering Evaluation/Cost Analysis (EE/CA) is recommended. | en |
