Using water quality criteria to sustain priority water uses downstream from mines Wilkes, Brian


Sustainable development in mining means that mines need to safeguard resource values such as water quality in their immediate vicinity. Once aquatic resource values are properly defined, water quality objectives should be set for receiving waters. If met, these ensure that the aquatic resource values are sustained. In general, objectives can be set. using criteria already in existence published by B.C. Environment and CCME. With receiving water objectives known at the planning stages, mines can engineer treatment works to deliver the effluent quality required. Therefore water quality criteria based objectives are useful to both sustain aquatic resources, and also for providing realistic targets for mine development or upgrade planning.
