Geophysical Investigation of Fault Zone Aquifers and Water Quality Assessment, Nkoteng, Cameroon This project aimed to contribute groundwater location maps and provide potable water access by mapping and drilling deep aquifer sources in the community. The team made water measurements using Hannah Instrument multi-parameter probes, anions and cations were analyzed using potable spectrophotometers, and Hach digital titrators were used for alkalinity. Geometrics Geode seismograph was used for seismic refraction, a StingR1 meter for VES, and […]

Contaminated groundwater is the major source of cholera disease in the capital city of Douala (population approx. 2 million) as residents use groundwater for drinking and daily activities. The project goal is to characterize the sedimentary basin in Douala by using two geophysical techniques, time domain electromagnetic sounding (TDEM) and magnetic resonance sounding (MRS) for better understanding of aquifer systems.

Project Overview Location: Benin, West AfricaStatus: CompleteFocus Area: Water Resource Management and Humanitarian EngineeringProject Partners: Colorado School of Mines (CSM), Université d’Abomey-Calavi (UAC), and regional water authorities Overview This GWB-funded initiative addressed one of West Africa’s most pressing challenges—protecting freshwater resources while building local geoscience capacity. The project had four key goals: Approach The field team deployed a combination of geophysical methods: Students from UAC and CSM collaborated to design and build instruments, conduct field […]
Argentina
Project Overview Location: Chaco Province, ArgentinaStatus: CompleteProject Partners: Universidad Nacional de San Martín (UNSAM), Geoscientists without Borders® (GWB)Focus Area: Water Security and Community Resilience Overview In the rural Chaco region of Argentina, many Indigenous and farming communities face chronic water shortages and dangerously high levels of arsenic and salinity in shallow wells. This GWB-funded project brought geoscientists, students, and local organizations together to apply geophysical methods to locate new, safe groundwater sources. Approach Using electrical […]
