Guidance on the Authorisation of Direct Discharges to Groundwater
Year: 2014
This guidance addresses direct discharges to groundwater from point sources of potential pollution. It supplements the earlier report published by the EPA in 2011 entitled “Guidance on the Authorisation of Discharges to Groundwater” which focused on the technical assessment of indirect discharges to groundwater.
Assessment and Forecasting of Drought Flow Conditions in Irish Rivers
An assessment of drought flow conditions in Irish Rivers in the years 1989, 1990 and 1991 including a comparison with 1975 and 1976, December 2012
Year: 2012
The most severe drought flows recorded occurred in 1975 and 1976. The climatic conditions that caused those droughts are examined in this document. The drought flows of 1989, 1990 and 1991 are compared with 1975 and 1976.
Review of the EPA Hydrometric Programme
This report provides details of the review carried out of the EPA Hydrometric Programme, December 2012
Year: 2012
This review investigates the work undertaken by the Hydrometric and Groundwater Section of the EPA and the many activities that utilise the hydrometric data generated by the section. A review of individual hydrometric stations was conducted for the prioritisation of future hydrometric programmes. The review also outlines recommendations for the future implementation of the EPA–Local Authority hydrometric programme
Classification of Hazardous and Non-Hazardous Substances in Groundwater
Year: 2012
The Environmental Protection Agency have published a list of hazardous and non-hazardous substances relating to their potential risk for groundwater pollution. Hazardous substances must be prevented from entering groundwater, and the input of non-hazardous substances must be limited.
Methodology for Establishing Groundwater Threshold Values, the Assessment of Chemical and Quantitative Status for Groundwater and Groundwater Trends
Year: 2012
Information on the establishment of Threshold Values and the methods and procedures used to assess the chemical and quantitative status of groundwater bodies. Includes outline of the assessment of pollution trends and trend reversal.
Guidance on the Authorisation of Discharges to Groundwater
Version 1 - December 2011 , June 2011
Year: 2011
This provides a framework for the criteria considered important for granting or refusing an authorisation for discharge to groundwater. It addresses risk screening, appropriate levels of technical assessment, prediction of impact on groundwater quality and appropriate monitoring for different types and scales of discharges.

This provides a framework for the criteria considered important for granting or refusing an authorisation for discharge to groundwater. It addresses risk screening, appropriate levels of technical assessment, prediction of impact on groundwater quality and appropriate monitoring for different types and scales of discharges.
Poorly Productive Aquifers - Monitoring Installations and Conceptual Understanding
Year: 2010
A step by step guide to the establishment and installation of monitoring catchments in poorly productive aquifers. The document provides information on the project background and approach, borehole drilling, the construction and installation of wells and the hydrological characteristics of each catchment.
Towards Setting Guideline Values for the Protection of Groundwater in Ireland
EPA Groundwater Interim Report, January 2003
Year: 2003
This document presents proposals for the setting of environmental quality objectives and standards for groundwaters through the use of ‘guideline values’. A separate document is considered necessary for groundwaters because the issues involved in the setting of environmental quality objectives and standards for groundwaters are quite different to those that arise in the setting of environmental quality objectives and standards for surface waters. This is because groundwaters, in their pristine condition, can vary considerably from one groundwater body to another due to the influence exerted by the particular geology of the area within which the body exists.
