A revised national assessment of risk to groundwater from diffuse mobile organics (DMOs) has been carried out in the Irish hydrogeological context. The original
Article V risk assessment that was submitted by the Environmental Protection Agency (EPA) to the European Commission (EC) in March 2005 was limited by the
availability of pressure information and understanding of environmental fate and transport characteristics of DMOs. The Eastern River Basin District (ERBD) project
was subsequently commissioned by Dublin City Council (DCC), on behalf of the Department of Environment, Heritage and Local Government (DEHLG), to study
risk to groundwater in greater detail, with the intent of informing future monitoring needs and a Programme of Measures required by the European Union (EU) Water Framework Directive (WFD).

The basic objectives and tasks of the study were to:

  • Improve the understanding of pesticide-related pressures;
  • Research fate and transport characteristics of commonly used pesticides;
  • In the absence of groundwater monitoring data, develop and implement a risk assessment methodology that captures both the pressure information
    and incorporates relevant physical factors that control leaching of pesticides from soil to groundwater.

For the purposes of the revised risk assessment, DMOs are broadly defined as pesticides. Pesticides are used in a wide array of settings, including agriculture, forestry, transportation, (urban) amenity, and industry. Detailed survey records of pesticide usage in the agriculture and forestry were obtained with the assistance of the Pesticide Control Service (PCS) and Coillte, respectively. Estimates for other sectors, including usage by local authorities, are less satisfactory, and rely on limited records, general literature, and information from interviews. Degrees and patterns of use by non-agricultural and non-forestry sectors therefore remain uncertain. Nonetheless, the available information suggests that the largest quantities of pesticides are used in the agricultural sector for pest and weed control.

Who is involved?

Quite simply, everyone in Ireland has a role to play. This can be from something as simple as making sure you don’t pollute your local stream, or a local community working together to establish a Rivers Trust to enhance the rivers and lakes in their area, to a Government Department or Agency helping a Minister implement a new policy to help protect and enhance all our waterbodies.

This website has been developed and is maintained by the Environmental Protection Agency, and is a collaboration between the Department of Housing, Planning and Local Government, the Environmental Protection Agency, and the Local Authority Waters and Communities Office.

LAWCO

Local Authority Waters Programme

The Local Authority Waters Programme coordinates the efforts of local authorities and other public bodies in the implementation of the River Basin Management Plan, and supports local community and stakeholder involvement in managing our natural waters, for everyone’s benefit.

EPA

Environmental Protection Agency

The EPA is responsible for coordinating the monitoring, assessment and reporting on the status of our 4,829 water bodies, looking at trends and changes, determining which waterbodies are at risk and what could be causing this, and drafting environmental objectives and measures for each.

DECLG

Department of Housing, Planning and Local Government

The Department is responsible for making sure that the right policies, regulations and resources are in place to implement the Water Framework Directive, and developing a River Basin Management Plan and Programme of Measures that will be implemented after public consultation and sign off by the Minister.
