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 ...

Sampling acid mine drainage (AMD) impacted sediments is complex requiring appropriate field sampling techniques to ensure representative samples which are both repeatable and reproducible. This report examines the important ...

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 ...

During this interim period of six months from May to October, 1994, 42 separate surface water sites were monitored. Surface waters were classified into nine discrete source categories. These are 1. Springs and seepage ...

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 ...
