Underground water exploration using natural potential method: case study the Olanchito Hospital

Abstract

Geophysical exploration methods have been widely used for underground water prospecting, being the most used the electrical and electromagnetic methods, which present some disadvantages such as: high cost of the equipment, large distances and time required on the surface for data collection. In this work we explore the use of alternative methods to the traditional ones, employing the PQWT equipment that has recently appeared on the market, which is presented as a low-cost, easy-to-use and fast-time equipment for data collection, which uses the so-called natural potential method for groundwater exploration. It was possible to locate a site for drilling a well in the Hospital of Olanchito, Yoro, proving that the information provided by the equipment, always combined with geological information from the area, can be used for the characterization of aquifers.
