The experience of using the DSS in Narayanganj and Bishkek indicated that for cities unable to afford more comprehensive pollution risk assessment procedures before formulating a groundwater management action plan, the system would provide an economical reconnaissance-level tool to help the non-specialist characterise and prioritise groundwater pollution threats according to their type, source, severity, scale, and possible impact on different end uses and users. For the most poorly-resourced cities, this may be the first step in formulating an aquifer protection plan.
Points added to Decision Support System Tool from applying it to case-study
• Thoughtful interpretation of the options is needed to account for gradations for example in methods of waste disposal or geological protection of the aquifer. The reasons for any decision should be documented.
