Lake and trac Historically Polluted Site pressures

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. Impacts from historically Polluted sites include nutrient, organic, chemical and sediment pollution.根据《水框架指令》（Water Framework Directive），存在未达水质目标风险的水体已被识别出显著压力源。尽管每个水体均存在多种压力源，但显著压力源是为改善水质而必须加以管控的压力类型。多数水体均存在多种显著压力源。为明确各类水体的显著压力源，已开展一套严谨的科学评估流程。该评估整合了超过140份数据集、一系列建模工具，以及来自地方政府、爱尔兰内陆渔业局与环境保护署（EPA）的一线执法与实地调研人员的本地实操知识。历史污染场地带来的环境影响涵盖营养物污染、有机污染、化学污染与沉积物污染。
