WebThis means that the barometric efficiency of the aquifer is close to 0.95 (±0.05). A barometric efficiency of this magnitude is quite exceptional and implies that its structure is very rigid and that it is well sealed off by confming sediments. The barometric efficiency of most confined aquifers is between 0.20 and 0.75 (Todd, 1967, p. 159).
