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 ...

Acid mine drainage (AMD) is a major environmental pollutant of both surface and ground waters. Intensive sampling of drainage from mine adits has revealed a seasonal variation in the Zn:Cu ratio. This is linked to secondary ...

This review examine the action of acid mine drainage (AMD), which is a multifactor pollutant, on surface waters. It affects aquatic ecosystems via a number of direct and indirect pathways. Major impact areas are coastal ...

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 ...

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 ...

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 ...

Metal Content was determined in soil and vegetation around the eastern zone of the disused copper and sulphide mines at Avoca in Co. Wicklow (south-east Ireland). A 250 x 250 m grid survey was conducted covering a total ...

The discharge of acid mine drainage (AMD) from sulphur bearing mineral deposits causes iron to precipitate as hydroxides and the formation of ochreous deposits on the substrate of the receiving river system. The sediments ...

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 ...

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 ...
