Lake and TRaC Urban Run-off Pressures

Published by Environmental Protection Agency

Significant pressures have been identified for waterbodies that are At Risk of not meeting their water quality objectives under the Water Framework Directive. While there are a multitude of pressures in every waterbody, the significant pressures are those pressures which need to be addressed in order to improve water quality. Many of our waterbodies have multiple significant pressures. A robust scientific assessment process has been carried out to determine which pressures are the significant pressures. This has incorporated over 140 datasets, a suite of modelling tools, and local knowledge from field and enforcement staff from the Local Authorities, Inland Fisheries Ireland and EPA. Urban run-off or diffuse urban pressures are mainly caused by misconnections, leaking sewers and runoff from paved and unpaved areas. Impacts from diffuse urban pressures include nutrient, organic and sediment pollution.
