Île de la Gonâve, Groundwater Exploration

West La Gonave Groundwater Exploration Program

Project Description


Northwater provided professional geology and geophysical services to support the on-going mission to discover groundwater in the western portion of the island of La Gonave, Republic of Haiti. This region of Haiti is of the most remote in the country and the geologic and logistical conditions make it difficult to find groundwater resources. This area of Haiti is known as having the lowest water availability of any populated place in the world. Many of the residents walk up to 12 miles round-trip to secure water that is brackish and only used for cooking, cleaning and animals.

Northwater performed hydrogeological reconnaissance and an electromagnetic geophysical investigation applying CSAMT/MT geophysics technology. A two-week field study was performed which resulted in the development of 40 km of regional resistivity transects. Most of the study was performed on-foot using donkeys and mules to assist with equipment transport. Logistics were extremely challenging and field conditions were very remote and rugged.

Two separate exploration areas were targeted based on the study; an upper plateau and a lower plaine. It was determined that there were very good drilling targets in both the upper plateau and lower plaine. Seven exploration drill sites were recommended, requiring drilling depths ranging from 80 – 260 meters.

The exploration program is immediately commencing in the lower plaine with a high level of confidence that excellent sources of groundwater will be discovered at several sites there. An action plan is currently in development for the upper plateau, which requires deeper and more challenging drilling.
