Groundwater provides a significant proportion of rural dwellers in the developing countries with access to safe drinking water and will continue to do so in the future. Groundwater is fairly ubiquitous, but its conditions vary enormously and exploitation is often undertaken with limited understanding of hydrogeology and without sufficient evaluation of the resource. In some places, heavy water use for agriculture has led to over-abstraction and placed groundwater out of the reach of domestic users as water tables have fallen. There are also regions where groundwater quality is not fit for human consumption (e.g. due to a high level of arsenic, fluoride, iron or nitrates, or contamination from human impacts such as poor sanitation, oil spills or chemicals).
The objective of the Sustainable Groundwater Development theme is: Groundwater resources are properly considered and sustainably used for developing drinking water supply sources. The theme has three sub-topics:
- Handpump Technology
- Cost Effective Boreholes (includes machine drilling and manual drilling)
- Cost Effective Water Resource Management
