Canada: Mining and water Pollution

Water is essential to life on our planet. A prerequisite of sustainable development must be to
ensure uncontaminated streams, rivers, lakes and oceans. There is growing public concern
about the condition of fresh water in Canada. Mining affects fresh water through heavy use of
water in processing ore, and through water pollution from discharged mine effluent and
seepage from tailings and waste rock impoundments. Increasingly, human activities such as
mining threaten the water sources on which we all depend.
