Environmental factors to be considered in geothermal exploration / production in Dominica

Abstract

Dominica forms a part of the Volcanic Caribbees in the Lesser Antilles Island Arc and has nine active volcanoes whereas the other islands have one volcano per island. Southern Dominica is the most active part of the island and includes the Wotten Waven area, one of the sites due for geothermal exploration. Preliminary surface exploration in Wotten Waven suggests the possibility of the existence of a deep high-temperature reservoir. Dominica is known as the “Nature Island” of the Caribbean and therefore promotes eco-tourism. Very often geothermal sites are found in environmentally sensitive areas, often of historic and cultural importance. Wotten Waven falls into this category, hence the recommendations suggested. The purpose of this report is to serve as a guideline to the Government of the Commonwealth of Dominica regarding geothermal development. In the event of geothermal development, and despite being a clean and sustainable source, there are several factors to be taken into consideration due to potential impacts on the environment.
