The Spilsby Sandstone as an aquifer

The Spilsby Sandstone aquifer consists of a variably but often poorly cemented quartz sandstone up to about 30 m thick with alternating thin clays and marls. Yields are typically about 80 l/sec. Construction and development of water supply boreholes in the Spilsby Sandstone can be problematic due to the poor cementation of the unit. It can be the source of springs where it outcrops at the western edge of its extent.
