AN OBJECTIVE INDEX FOR THE ASSESSMENT OF THE CONTAMINATION OF SURFACE AND GROUND WATERS BY ACID MINE DRAINAGE

The latest publication in the reprint series of Water Technology Research Technical Report s is No. 22.  AN OBJECTIVE INDEX FOR THE ASSESSMENT OF THE CONTAMINATION OF SURFACE AND GROUND WATERS BY ACID MINE DRAINAGE

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 of such waters. The acid mine drainage index (AMDI) is calculated using a modified arithmetic weighted index using seven parameters most indicative of AMD contamination. These are pH sulphate, iron, zinc, aluminium copper and cadmium. Weighting was used to express the relative indicator value of each parameter. The pH and sulphate were considered to be of greatest indicator value as they were unaffected by sorption processes, while sulphate was also unaffected by natural neutralization processes. The AMDI as proposed is designed to detect and quantify contamination from AMD and to help categorize samples, quantify impact to receiving waters and to monitor recovery. The AMDI is fully evaluated and discussed.

Water Technology Research Technical report 19 Reissued by Tigroney Press

As part of an extensive study of the environmental impacts of the abandoned CU-S mines at Avoca in County Wicklow in Ireland, extensive studies were made of the river sediments and their toxicity. Originally written in 1995, this report examines the background to this study by reviewing the interactions of metals with the sediments including speciation, sorption processes (i.e. Interaction with particulate matter the role of hydrous oxides), as well as the sediment itself (i.e. sediment composition, grain size effects, transport and pollutant pathways). The toxicity of sediment-bound metals to aquatic organisms is also explored. The study explores the effects of acid mine drainage on the River Avoca.
