Abstract

This site in north-eastern New Brunswick, Canada, was developed as an open-pit copper mine in the early 1970s. The site was left in a severely disturbed state, contaminating the local drainage for over 10 years. Contamination to local runoff included low pH, high concentrations of lead, copper, zinc and iron and elevated concentrations of metals in general. Action taken to alleviate, the problems in the local drainage and establish a programme of site reclamation is described. The programme included water diversion, improvements in water quality control, site grading, material relocation and revegetation.
