The Permian of Northern England consists of over 1800 feet of dolomites, limestones, marls and evaporites, with arenaceous deposits at the base. Although of limited areal extent, a wide variety of lithologies are represented, largely interpretable in terms of the depositional environment at the western margin of the Zechstein Sea. The structure consists of a low east to south-easterly dip, together with faults, the largest of which trend east-west and attain maximum development in the south of Co. Durham. The geohydrology is controlled by the lithology and the structure. To the north of the Hartlepool Fault System the aquifer is unconfined, and represented chiefly by the Lower Magnesian Limestone and Basal Permian Sands. It has been indiscriminately developed in the past, and at present 24 m. g. d. are licensed for abstraction. In the south and around Hartlepool, the Middle Magnesian Limestone forms the main aquifer, being confined for most of its extent by drift or marls of the Lower Evaporite Group. A groundwater investigation of this area by the Northumbrian River Authority showed that analysis and extrapolation was made difficult by the presence of hydrological barriers due to faulting and basement 'highs'. Digital and analogue simulation techniques have been used, and results from the latter indicate a net 12 m. g. d. to be available without depleting resources.
