The results from these studies helped to determine the best location for a water well for the community. The combined information will be used to suggest a protocol for groundwater mapping in volcanic areas with complex geology for future projects.
A group from the Colorado School of Mines used a suite of geophysical tools to characterize subsurface water for the village of Chasnigua, Honduras. The village is small, with approximately 50 families (200 people) that rely on trucking their water to their homes. They have asked for assistance in developing water well, storage and distribution system. Honduras is economically one of the poorest countries in the western hemisphere, with about half the population below the poverty line. Consequently, the people do what they can to subsist on the land. This location is one with economic hardships and complex geology and hydrology.
The project was completed using a variety of surface geophysical tools: electromagnetic, SP, magnetics, magnetic gradiometry, and DC resistivity, to try to unravel the complex structure of the subsurface. Water samples were taken to analyze the physical properties of the near-surface and assist in the interpretation process.
