| Popis: | This paper is an update on a project initiated last year with a grant from SEG's Geoscientists Without Borders program. The project benefited from prior established relationships with water and sanitation administrators in the Municipality of Villanueva and with faculty and students from the Universidad Autonoma de Honduras, campus Valle Sula. The project rationale was the substantial need for a clean, reliable source of potable water for people living in the village of Chasnigua and the interesting geophysical challenges of an area complicated with volcanic/limestone terrain. Because of the geological complexity of this region, a suite of magnetic, magnetic gradient, direct current (dc)resistivity, and frequency-domain electromagnetic studies were performed. Soil and water sampling and testing, and topographic mapping of the terrain augmented this geophysical study. Through this effort, a site was identified that holds substantial promise for a sustainable subterranean water source. However, challenges have now moved from the technical to the social context as the person responsible for land on which most of our geophysical studies have focused, is now reluctant to allow water well drilling and completion on that land. In addition to the technical aspects of this project, this paper includes a discussion of approaches that may provide a more successful outcome with regard to social contextual challenges in which these type projects are inevitably immersed. |
