The impact of acid mine drainage (AMD) on lotic receiving waters is complex and difficult to assess. While low pH, elevated sulphate and metals all characterize AMD these vary both spatially and temporally, with high ...

Temporal and spatial comparisons of acid mine drainage (AMD) contaminated waters are difficult due to the complex physico-chemical nature of the pollutant. An objective index has been developed and evaluated for assessment ...

The rehabilitation of a mine producing acid mine drainage (AMD) involves four discrete steps. These are site characterization, the development of an AMD water quality management protocol, a remediation strategy and finally ...

Field toxicity experiments were conducted in the Avoca River (Ireland) during August and September 1994 in order to evaluate the toxicity of acid mine drainage (AMD) to a number of selected macro-invertebrate species. The ...

Water and suspended particulate matter (SPM) was collected at weekly intervals during low flow conditions from the Avoca River (May and August, 1994). The total concentration of Zn, Cu, Cd and Fe was measured in both the ...

Both sulphate and conductivity are excellent indicators of AMD contamination. This is due to sulphate being an end product of pyrite oxidation. Unlike pH, they are both extremely sensitive to AMD even where large dilutions ...
