Description of Research Interests
I carry out research within the broad area of environmental earth science, mainly on groundwater quality. My specific interests include: Rural groundwater quality problems, particularly nutrients and pesticides Groundwater vulnerability assessment and protection schemes Karst hydrogeology and karst groundwater protection Phosphorus loss to surface waters by different hydrological pathways Groundwater surface water interactions and integrated catchment management

Research Projects
Project title Nitrogen attenuation along delivery pathways in agricultural catchments
Summary This research projects aims to investigate nitrogen attenuation processes along groundwater pathways and in the hyporheic zone in two Irish agricultural catchments: an arable catchment in Co. Wexford and an intensive grassland catchment in Co. Cork. The research is being conducted in association with the Agricultural Catchments Programme based at Teagasc, Johnstown Castle, Wexford, as a doctoral project by Eoin McAleer.

Project title Evaluation and interpretation of groundwater monitoring data and the implications for groundwater in Ireland
Summary This project involves the analysis of groundwater data collected by the Environmental Protection Agency for the EU Water Framework Directive, with the aim of providing a better understanding of Irish groundwater quality and groundwater levels. The work on groundwater quality will include focused investigations into particular topics including (i) phosphorus in groundwater, particularly in the karst regions of the Western River Basin District, and the implications for surface water eutrophication, (ii) nitrate in groundwater in the South Eastern River Basin District: investigation of sources and pathways and quantification of load to rivers and estuaries, (iii) flow and quality relationships in karst springs. The research fellowship is being undertaken by Katie Tedd.

Project title Pesticide leaching to groundwater in Ireland
Summary This project formed part of a larger interdisciplinary project on Assessment of the vulnerability of groundwater to pesticide inputs from Irish agriculture (led by Dr. E. Cummins, University College Dublin). This component of the project involved field investigations of pesticide leaching to groundwater under a range of land uses, soil types and geological / hydrogeological conditions, on selected farms in eastern and southern Ireland. The research also involved analysis of existing Irish groundwater pesticide monitoring data. It was carried out as a Ph.D. project by Sarah McManus under my supervision, co-supervised by Dr. Karl Richards (Teagasc Johnstown Castle Research Centre).

Project title Environmental supporting conditions for groundwater dependent terrestrial ecosystems
Summary Groundwater Dependent Terrestrial Ecosystems (GWDTEs) are habitats where the water table is at or near the ground surface and they directly depend on groundwater for a significant proportion of their water supply. The EU Water Framework Directive requires Member States to ensure that all groundwater bodies maintain good groundwater quantity and quality, and as part of the task of classifying the status of groundwater bodies, assessments of groundwater-related significant damage to GWTDEs must be undertaken. This research project was commissioned to inform the development of appropriate status tests relevant to GWDTEs and to highlight knowledge gaps. The project investigated the development of trigger and threshold chemical values based on conceptual hydro-ecological models of selected GWDTEs. The research was undertaken by a postdoctoral research fellow, Dr. Sarah Kimberley, under my supervision as principal investigator.

Project title Evaluation of strategies to minimise nitrate leaching losses from tillage land
Summary This project aimed to evaluate different management strategies to minimise nitrate losses to groundwater from spring barley production systems. This involved an investigation of the unsaturated zone (using ceramic cups) below replicate small plots with different treatments (mustard cover crop, natural regeneration, and no vegetation cover) and an investigation of both unsaturated and saturated zones below three larger field plots. Travel times through the unsaturated and saturated zones were investigated. The work aimed to contribute to the research base for formulating policy relating to the EU Nitrates Directive (1991/676/EC) and the Water Framework Directive (2000/60/EC). The research was carried out as a Ph.D. project by Alina Premrov; I was the main academic supervisor and the research was co-supervised by Dr. Karl Richards and Dr. Richard Hackett(Teagasc).
