Long Lake Gold Mine: arsenic

In July 2012, the Ministry of Environment and Climate Change notified Public Health Sudbury & Districts that there were elevated levels of arsenic in the water at the south west end of Long Lake due to run off from the abandoned Long Lake Gold Mine.

Public Health Sudbury & Districts notified affected residents of potential risks associated with water use. The Ministry of Northern Development and Mines (MNDM) initiated a detailed remediation proposal.
