There exists an emerging market for groundwater professionals in the developing world. The majority of work in the developing world has focused on water supply issues. More recently, opportunities to assess and remediate groundwater contamination have developed. Projects are conducted by government agencies, international aid organizations, non-government organizations, universities, and for-profit consulting firms. There is little to no country by country coordination of activities. One organization may be working on a groundwater project in a specific resource area without knowledge of similar work by another organization in the same area or country. The assessment and remediation of groundwater contamination in the developing world is challenging and rewarding. This session features presentations regarding specific groundwater assessment and remediation projects in the developing world with an emphasis on innovative, low-cost technologiesand lessons learned.
