Public Supply Source Protection Areas Ireland (ROI) ITM

Groundwater sources, particularly public, group scheme and industrial supplies, are of critical Importance in many regions. The Public Supply Source Protection Areas Dataset survive Source Protection Areas (SPAs) around Groundwater abstraction points that are managed by Irish Water to supply Public Water Supply Schemes across Ireland. The objective of the SPAs is to provide protection by placing tighter controls on activities within all or part of the zone of contribution (ZOC) of the source. The Zone of Contribution (ZOC) is the land area that contributes water to the well or spring. Two Source Protection Areas (SPAs) are delineated. The Inner Protection Area (SI), designed to protect against the effects of human activities that might have an immediate effect on the source and, in particular, against Microbial pollution. The outer Protection Area (SO), encompassing the models of the zone of contribution (ZOC) to the Groundwater abstraction point (e.g. borehole or spring).地下水水源，尤其是公共供水、集中供水方案及工业供水水源，在诸多地区均具有至关重要的地位。 本公共供水水源保护区数据集（Public Supply Source Protection Areas Dataset）涵盖爱尔兰水务公司（Irish Water）为全爱尔兰公共供水方案（Public Water Supply Schemes）所管理的地下水取水点（Groundwater abstraction points）周边的水源保护区（Source Protection Areas, SPAs）。水源保护区（SPAs）的设立目标是通过对水源补给区（Zone of Contribution, ZOC）全部或部分区域内的活动实施更严格管控，以此实现水源保护。地下水补给区（ZOC）指为水井或泉眼补给水源的陆地区域。 本次共划定两类水源保护区（SPAs）：内层保护区（Inner Protection Area, SI）旨在防范可能对水源造成直接影响的人类活动，尤其针对微生物污染（Microbial pollution）；外层保护区（Outer Protection Area, SO）则覆盖地下水取水点（如钻井（borehole）或泉眼（spring））的补给区模型范围。
