Many Celtic regions comprise hard fractured rock aquifers and hilly terrain. They are generally regions which have also been affected by repeated glaciation and deglaciation during the Pleistocene period. This has influenced their hydraulic properties and the groundwater flow systems which have developed. Geophysical borehole logging provides a useful method to examine the occurrence of groundwater, water inflows and the movement of water in local and regional groundwater flow systems. The downhole measurements show that wellbore flow, aquifer layering and separate groundwater circulations are common features of the hydrogeology.

Groundwater in the Celtic Regions: Studies in Hard Rock and Quaternary Hydrogeology
This book covers a diverse range of hydrogeological environments that occur in the Celtic regions of Britain and Ireland. These include hard rock aquifers of Lower Palaeozoic and Precambrian age, generally dominated by fracture flow within a shallow zone of weathering; Carboniferous Limestone aquifers, often characterized by conduit flows in karstic systems; dual-porosity Permo-Triassic sandstone aquifers; and Quaternary deposits, many of which form shallow granular aquifers. The papers presented here address a number of current issues common to the Celtic regions, including: groundwater protection policies, groundwater management in karst aquifers, groundwater development in Quaternary aquifers, groundwater evaluation in data-scarce aquifers and groundwater supplies to small island communities.
