ScienceWater tracing involves tagging water to see where it goes. The time the tracers take to get from one point to the other is also usually recorded. It is most commonly used in karst environments to ascertain groundwater flow rates, directions and catchment definitions (Zone of...

ScienceDifferent aquifers have differing abilities to store and transmit water. Based on the hydrogeological characteristics and on the value of the groundwater resource, GSI has classified Ireland’s land surface into aquifer categories. GSI Aquifer classes are divided into three...

The groundwater vulnerability concept is based largely on the question “can water and contaminants move in the subsurface materials (soil and subsoil) and/get down to groundwater easily?” Groundwater is most at risk where the subsoils are absent or thin and in areas of karstic...

The Groundwater Subsoil Permeability map classifies how easy water can infiltrate subsoils downwards at any point in the land surface. Permeability across the country is classified as either ‘High’, ‘Moderate’ or ‘Low’. This map is used to determine groundwater vulnerability...
