The numerical treatment of leaky aquifers in the short time range is complicated because it requires the use of very refined meshes. This range of time includes not only pumping tests but also many regional studies because the definition of short time range depends on the thickness and diffusivity of the aquitard. The groundwater system of Mexico City is an example in which the short time range extends well beyond the whole life span of the pumping wells. In this paper a procedure which permits the avoidance, to a large extent, of these difficulties is explained; it is based on the integrodifferential equations approach. In addition a method that can be applied to control the error is presented.
