Groundwater is among the world’s most important natural resources. It provides drinking water to rural and urban communities, supports agriculture and industry, sustains wetland and riparian ecosystems, and maintains the flow of rivers and streams. In many places, groundwater resources are susceptible to risks of overuse and contamination. Its sustainable management is increasingly critical; especially in climate-sensitive geographic areas such as islands and arid lands.
My main interest is in researching karst groundwater sustainability because aquifers storing groundwater in karst systems are commonly found throughout my home country, Jamaica, and other islands in the Caribbean. In Arizona, the major karst aquifer system is found in the north in the Coconino Plateau area; which includes the city of Flagstaff, and the Grand Canyon region. The physical characteristics of karst groundwater systems make them highly susceptible to pollution and climatic influences. Geologic features of karst landscapes, such as sinkholes, act as quick pathways for pollutants to be transported to the aquifer, given that there are little or no soil layers to filter pollutants en route to the aquifer.
