A confined aquifer has a thickness of 105m and an area of 11x10 9 m 2 . Over a period of 35 years, the aquifers supplies 100 x 10 6 m 3 of water. This quantity is drawn entirely from storage and the potentiometric level drops by an average of 2 m per year. The specific storage due exclusively to the expansion or contraction of the water has been determined to be 8 x 10 -7 m -1 . What percentage of the pumped water is supplied by compression of the aquifer skeleton?

A confined aquifer has a thickness of 105m and an area of 11x10 9 m 2 . Over a period of 35 years,
the aquifers supplies 100 x 10 6 m 3 of water. This quantity is drawn entirely from storage and the
potentiometric level drops by an average of 2 m per year. The specific storage due exclusively to
the expansion or contraction of the water has been determined to be 8 x 10 -7 m -1 . What
percentage of the pumped water is supplied by compression of the aquifer skeleton?
