UNESCO World Water Assessment Programme
Hello again - Have a look at the report below (also posted on the wiki). It is an overview of the entire water sector in Uganda but a few chapters will be directly relevant to us:
Chapter 3 - Summary of Uganda's freshwater sources including quality monitoring
Chapter 4 - Summary of rural water supply
In chapter three there is a description of a current water quality monitoring program for groundwater which means we may be able to find some water quality data for, at minimum, the region we are working with.
