ENVIRONMENTAL IMPACT OF ACID MINE DRAINAGE ON THE RIVER AVOCA: Metal Fluxes in water and sediment. Part II. Metal Contamination of Riverine Sediments
(Tigroney Press, 2017-06-01)
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 ...
AN OBJECTIVE INDEX FOR THE ASSESSMENT OF THE CONTAMINATION OF SURFACE AND GROUND WATERS BY ACID MINE DRAINAGE
(Tigroney Press, 2017-08)
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 ...
WATER QUALITY OF THE SURFACE WATERS AT AVOCA MINES AND THE AVOCA RIVER: Interim Report May to October, 1994.
(Tigroney Press, 2017-06-08)
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 ...
PROCEDURE FOR THE ESTIMATION OF THE IMPACT OF ACID MINE DRAINAGE TO SURFACE WATERS AND ITS MANAGEMENT
(Tigroney Press, 2017-08)
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 ...
ENVIRONMENTAL IMPACT OF ACID MINE DRAINAGE ON THE AVOCA RIVER: Acute Toxicity Experiments in the Field Using Macro-invertebrates
(Tigroney Press, 2017-06-08)
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 ...
A Synoptic Overview of the Avoca-Avonmore Catchment and the Mines
(Tigroney Press, 2017-05-15)
As part of a long term study of the effects of the abandoned Cu-S mines at Avoca County Wicklow in Ireland a short overview was created of the Avonmore-Avoca River Catchment including summaries of tributaries; topography ...
INFLUENCE OF POSSIBLE SECONDARY SULPHATE MINERALIZATION ON THE IMPACT OF ACID MINE DRAINAGE TO SURFACE WATERS
(Tigroney Press, 2017-06-08)
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 ...
ENVIRONMENTAL IMPACT OF ACID MINE DRAINAGE ON THE AVOCA RIVER: Metal Fluxes in Water and Sediment. Part III. Metals in Water and Suspended Particulate Matter.
(Tigroney Press, 2017-06-08)
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 ...
ENVIRONMENTAL IMPACT OF ACID MINE DRAINAGE ON THE RIVER AVOCA: Metal Fluxes in Water and Sediment. Part I. Introduction to Metal Accumulation in Riverine Sediments
(Tigroney Press, 2017-05-15)
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 ...
A SURVEY OF SOIL AND VEGETATION IN THE AREA SURROUNDING THE AVOCA MINES, Co. WICKLOW
(Tigroney Press, 2017-05-24)
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 ...
