These are NRW Aquifer topology superficial [Aquifer Designation Superficial Deposits] and NRW Aquifer topology bedrock [Aquifer Designation Bedrock Geology]. Aquifer designations identify the potential of the geological strata to provide water that can be abstract and have been defined through the assessment of the underlying geology. The designations are attributed directly to British Geological Society (BGS) 1:50K. Bedrock geology (formerly known as 'solid' geology by BGS) is a term used for the main mass of rocks forming the Earth and present everywhere, whether exposed at the surface in outcrops or concealed beneath superficial deposits or water. Geology less than 1.8 million years in age are referred to as Superficial Deposits. Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back about 1.8 million years from the present. They rest on older deposits or rocks referred to as Bedrock. Aquifer designation consists of two datasets.

They usually provide a high level of water storage. They may support water supply and/or river base flow on a strategic scale; Secondary Aquifers A: permeable strata capable of supporting water supplies at a local rather than strategic scale and in some cases forming an important source of base flow to rivers; Secondary Aquifer B: predominantly lower permeability strata which may in part have the ability to store and yield limited amounts of groundwater by virtue of localised features such as fissures, thin permeable horizons and weathering; Secondary Undifferentiated: In cases where it has not been possible to attribute either category A or B to a rock type; Unproductive Strata: these are geological strata with low permeability that have negligible significance for water supply or river base flow.
