Early insights indicator report: Nitrogen concentrations in selected major rivers, January-December 2024
Summary: The purpose of this report is to provide an early insight into nitrogen concentrations in major rivers in Ireland, in advance of the more comprehensive annual water quality assessments.
The report is based on the nitrate concentration data for 20 representative river monitoring sites which are situated at the most downstream monitoring locations on the major rivers around Ireland. A map of the locations of the sites and the catchments they represent is presented in Figure 1. This current report includes data for January to December 2024 inclusive. Comparisons are made with the same period in previous years for context. Analysis is also presented to demonstrate how representative these early insight indicator data when compared to data for the full national monitoring dataset which will be published in June 2025.
