Peru

Hydrogeophysics for community monitoring of groundwater in degraded dry forest quebradas of Peru This project aimed to address water scarcity and ecosystem degradation using low-cost geophysical equipment in Lobitos, Peru, by using DC resistivity meter for VES, Piezoelectric sensor on sledgehammer, 500 MHz USB oscilloscope for refraction surveys, and enhanced interpretation of VES and custom built GPR for constant-offset transects with 100 MHz antenna for common-midpoint surveys for near-surface stratigraphy and water table level determination

Peru

Zurite is a small rural village of approximately 4,000 people in the Andean highlands of Peru. All families in Zurite rely, at least in part, on agriculture. The climate is strongly seasonal, with rainfall from December to May, and a dry season from June through November. The hydrology of the Ramuschaka Watershed, which drains through the western sector of Zurite, has not been quantified. The community requires detailed information to guides sustainable water management practices.

Nigeria

Integrated groundwater potentials and aquifer vulnerability study in parts of Anambra State, Nigeria This project aims towards improving potable water access and supply for the benefit and socio-economic wellbeing of inhabitants based on scientific data and recommendation on sustainable exploitation, development, and management of groundwater resources in the Awka Capital Territory by using Vertical electrical sounding (VES), Electromagnetic (EM) and Electrical Resistivity Tomography (ERT) techniques to interpret geo-electric sections and model to give the subsurface

Nepal

Understanding high mountain aquifers to source drinking water in the Sagarmatha National Park This community-driven project aims to combines science, applied science, and human dimensions with the goal of solving the water problems of two communities in the Sagarmatha National Park (SNP), Nepal by using a combination of water quality and quantity testing, geological mapping, and an Electrical Resistivity Tomography (ERT) survey for the communities of Phortse and Lobuche to have identified the need for

Myanmar

Millions of people in Myanmar suffer from annual water shortages. During the 2018 dry season, an estimated 24,400 villagers in Mon state suffered from water scarcity. Currently, only 69% of households have access to improved drinking water as their main source. This project aimed toward improving water security in rural Mon state by enabling engineers, students, and researchers to use electrical geophysical methods to locate sustainable water supplies. By featuring a Trainer-of-Trainers (TOT) capacity-building model

Milingimbi, Australia

Milingimbi is a remote island and has an aboriginal community of about 1,600. Groundwater is the only source for water supply to the community, and at the end of the wet season the resources are scarce and there is a severe risk of saltwater intrusion into the borefield. The project used multiple geophysical and hydrogeological techniques to investigate saltwater intrusion and groundwater dynamics beneath the island.

Capacity building in Hydrogeophysics at University of Malawi

This project aimed to develop the local geoscience capacity in Malawi to provide locally sourced solutions to water resource problems by creating 2-D profiles using ABEM Terrameter 1000 with a 64-channel electrode switch and cable set along with a license for RES2DINV processing software. The project team located water sources for 4 local villages- the area surrounding Mpyupyu Hill (Kimu), the area surrounding Chanda Hill (Jimu and Kuchilimba), and the fishing villages at Kachulu harbor

Leogane, Haiti

The residents of Leogane, Haiti (Pop. 90,000) have historically relied on shallow hand-excavated wells as a source of water. The community is near the epicenter of the 2010 Haiti Earthquake, where humanitarian aid has resulted in upgrades to the infrastructure, included construction of 11 km of paved roads and 2 km of storm water drainage structures to mitigate flooding and waterborne disease. After construction, many of the shallow wells in Leogane, some of which had

Geophysics to Enhance Agricultural Productivity and Livelihoods of Smallholder Farmers through Improved Groundwater Management of the Vientiane Plain

The main aim of this project was to contribute towards the hydrogeological maps’ development, and delineate good and poor quality water to lower the risk of well failure on the Vientiane Plain. The team used near-surface geophysical techniques- Fast sampling TEM (Zonge Engineering NanoTEM system), Electrical Resistivity Tomography [ERT (IRIS Instruments Syscal Pro Switch 96)], Ground Penetrating Radar [GPR (MALA GroundExplorer HDR) and Frequency domain electromagnetic induction conductivity meters (GF Instruments CMD Explorer and Dualem

Kenya

Geophysical Studies to Improve Groundwater Resource use in the Kakuma Refugee Camp and Town Site This project was aimed to provide a reliable water resource to the rapidly expanding Kakuma Refugee Camp and Town site, home to over 185,000 African war refugees. By using advanced geophysical technology including 2-D resistivity (ERT), MRI surveys and knowledge of local geology the team located drilling sites for 6 new wells This project’s outcomes influenced The United Nations High
