Bathing Water Quality Prediction Using An Integrated Catchment And 3-D Coastal Hydrodynamic Model, John O'Sullivan, Zeinab Bedri, Aisling Corkery, Louise Deering, Katalin Demeter, Wim Meijer, Barthelomew Masterson, Gregory O'Hare

Conference papers

Under the new European Union Bathing Water Directive (2006/7/EC) which comes into force in 2014, more stringent bathing water quality standards, defined in terms of Escherichia coli (E.coli) and Intestinal Enterococci (I.E.), will apply in Irish bathing waters. Compliance with these standards is ensured through a structured water quality monitoring programme that is published by Authorities with responsibility for bathing water areas in advance of each bathing season. The directive recognises that elevated levels of faecal coliform bacteria in bathing areas can derive from the overland transport of waste from livestock in the rural fraction of river catchments. On days …

Environmental Consequences Of A Power Plant Shut-Down: A Three-Dimensional Water Quality Model Of Dublin Bay, Zeinab Bedri, Michael Bruen, Aodh Dowley, Barthelomew Masterson

Articles

A hydro-environmental model is used to investigate the effect of cessation of thermal discharges from a power plant on the bathing water quality of Dublin Bay. Before closing down, cooling water from the plant was mixed with sewage effluent prior to its discharge, creating a warmer, less-saline buoyant pollutant plume that adversely affects the water quality of Dublin Bay. The model, calibrated to data from the period prior to the power-plant shut-down (Scenario 1), assessed the water quality following its shut-down under two scenarios; (i) Scenario 2: continued abstraction of water to dilute sewage effluents before discharge, and (ii) Scenario …

Real-Time Prediction System Of Bathing Water Quality At Bray, Co. Wicklow, Ireland, Zeinab Bedri, John O'Sullivan, Aisling Corkery, Louise Deering, Katalin Demeter, Wim Meijer, Gregory O'Hare, Bartholomew Masterson

Conference papers

Variations in water quality at recreational bathing beaches can have significant impacts with respect to compliance with related water quality standards, such as Directive 76/160/EEC. The “Blue Flag” award which bases its water quality standards upon the guideline E.coli levels of Directive 76/160/EEC, has become the measure of recreational value of bathing areas. Loss of such designations can have significant impacts with respect to local tourist economies. A revised Bathing Water Directive (Directive 2006/7/EC) came into force in 2006 and will supersede the existing 1976 Directive with effect from December 2014.

The revised Directive gives stronger focus on the protection …
