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 ...

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 ...

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 ...

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 ...
