ENVIRONMENTAL IMPACT OF ACID MINE DRAINAGE ON THE AVOCA RIVER: Acute Toxicity Experiments in the Field Using Macro-invertebrates
(Tigroney Press, ireland, 2017-06-08)Technical Report (Water Technology Research), 18, 1994-11-1 (reissued 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 ... -
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, ireland, 2017-06-08)Technical Report (Water Technology Research), 21, 1, 1995-04-01 (reissued 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 ... -
Evaluation of the fisheries potential of the Avoca catchment
(Tigroney Press, ireland, 2017-08)Technical Report (Water Technology Research), 9, 1, September 1992 (reissued 2017-08-16)The Avoca-Avonmore is a potential salmonid river which has been severely impacted by industrial development throughout its length but especially in its lower reaches due to the abandoned Cu-S mines at Avoca. This study ... -
FIELD ASSESSMENT OF ACID MINE DRAINAGE CONTAMINATION IN SURFACE AND GROUND WATERS
(Tigroney Press, ireland, 2017-06-08)Technical Report (Water Technology Research), 14, 1, 1995-01-01 (reissued 2017-06-08)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 ... -
A SUBSTRATE CLASSIFICATION INDEX FOR THE VISUAL ASSESSMENT OF THE IMPACT OF ACID MINE DRAINAGE IN LOTIC SYSTEMS
(Tigroney Press, ireland, 2017-08)Technical Report (Water Technology Research), 24, July 1995 (reissued 2017-08)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 ... -
WATER QUALITY OF THE SURFACE WATERS AT AVOCA MINES AND THE AVOCA RIVER: Interim Report May to October, 1994.
(Tigroney Press, ireland, 2017-06-08)Technical Report (Water Technology Research), 12, 1994-11-01 (reissued 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 ...
