LONG-RANGE SPREADING OF METALS FROM A MINE WASTE DEPOSIT
The spreading of heavy metals from a metal rich deposit in surface waters is examined from measured concentrations in draining rivers and a series of lakes downstream the deposit, during a period of 3 years. The decreasing concentrations observed in the lakes appear to be the result of mixing of effluents from the deposit with water from other origins and with different metal content. However, the non-conservative behaviour of the metals indicates a continuous withdrawal of metals due to sedimentation processes that can be described by a simple time-dependent model.
