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. At the close of the Hallstatt period the Celts soils. Land use includes grassland characteristic occupied much of central and western Europe, of much of lowland Ireland, upland pastoral and Britain and Ireland were home to the Gaels, farming typical of much of central Wales and the Picts and the Britons. Nowadays, the land of arable cultivation in eastern Scotland. Forestry the Britons is divided between England and is also extensive. Many lowland coastal areas Wales, and the Celtic regions are considered support the highest population density as well as principally as Wales, south-west England (the traditional heavy industry, manufacturing and Cornish peninsula), Northumbria, Scotland and service industry, and mining has left its impact Ireland.
