Geophysica. methods a.e often used to a.d in explora.ion for sa.e a.d a.unda.t groundwa.er. In pa.ticula. resistivity a.d seismic refra.tion methods a.e helpful in determining depth to bedrock a.d zones of sa.ura.ion in the subsurfa.e. However the expense of these instruments ($5000 to $20,000) ha. resulted in their limited use in developing countries. This pa.er describes how to construct these devices for less tha. $250 ea.h. The instruments a.e sma.l, light a.d robust a.d a.e a. useful for groundwa.er explora.ion a. the commercia. models for sha.low a.uifers (less tha. 35 m deep) where wells ca. be ha.d dug, a.gured or drilled with sma.l porta.le drill rigs. Da.a.interpreta.ion ca. be a.complished quickly in the field with free softwa.e implemented on a.la.top computer. a.suite of geophysica. instruments a.d softwa.e ca. therefore be a.sembled for less tha. $850. This pa.er gives the design for these instruments a.d essentia. informa.ion needed to use them. It is hoped tha. these inexpensive geophysica. instruments ca. be widely distributed a.ong drillers a.d a.d workers in developing countries, improving the success ra.e of wa.er wells.
