Assigning Ecological Status to Unmonitored Water Bodies in 2016-2021
A technical report outlining the methodologies used in surface waters and groundwaters, July 2024
Year: 2024
In Ireland, almost 60 per cent of identified Water Framework Directive (WFD) water bodies1 are monitored. The current ecological status assigned to these waterbodies is based on the results of the 2019-2021 national water quality monitoring programme (EPA, 2021). The status for those water bodies that are not monitored must be assigned by other means. The purpose of this technical paper is to outline how status is assigned to the remaining unmonitored surface waters and groundwaters.
