The Fell Sandstone and Border Group as an aquifer

The Fell Sandstone and Border Group aquifer consists of friable, quartz-rich sandstones with minor pebbly and silty bands. It is up to about 300 m thick. Yields are quite variable due to variations in the degree of jointing but typically less than 10 l/sec from the upper parts of the aquifer. Water is soft at outcrop but becomes harder down dip particularly below cover.
