摘要英国和爱尔兰的凯尔特地区地质复杂多样，支持一系列具有区域和地方重要性的基岩含水层和松散的第四纪含水层。在基岩中，含水层单元往往很小，地下水流动路径短，在很大程度上依赖于裂隙流动。地下水在历史上一直发挥着重要的社会作用，现在正重新受到人们的关注。地下水质量总体上是良好的，适合饮用，只需最低限度的处理。然而，许多水井容易受到来自点源的微生物和化学污染物的影响，如农家庭院和化粪池系统，来自分散农业来源的硝酸盐浓度在某些地区引起关注。在一些凯尔特人的土地上，废弃煤田和废弃金属矿附近不断上升的矿井水造成的污染也是一个问题。
Abstract The Celtic regions of Britain and Ireland have a complex and diverse geology which supports a range of regionally and locally important bedrock aquifers and unconsolidated Quaternary aquifers. In bedrock, aquifer units are often small and groundwater flow paths short and largely reliant on fracture flow. Groundwater has fulfilled an important social role throughout history, and is now enjoying renewed interest. Groundwater quality is generally favourable and suitable for drinking with minimal treatment. However, many wells are vulnerable to microbiological and chemical pollutants from point sources such as farmyards and septic tank systems, and nitrate concentrations from diffuse agricultural sources are causing concern in certain areas. Contamination by rising minewaters in abandoned coalfields and in the vicinity of abandoned metal mines is also a problem in some of the Celtic lands.
