According to an article in Wikipedia
about water supply and sanitation in Uganda, by 2010, 38% of the population in Uganda had no access to an improved water source. People rely on unsafe sources such as rivers, lakes an unprotected wells.

Spring water - Unfiltered: Had E. coli growth. Swamp water- Unfiltered: Had E. coli growth
Spring water -Filtered: No growth. Swamp water- Filtered: No growth.
Results
![Page 21: Nabisunsa Girls School, Kampala, Uganda. United we stand To carry up our flag To fight for our nations health Our hearts and minds we pour The water](https://reader038.vdocument.in/reader038/viewer/2022110116/5517b3a4550346892b8b4599/html5/thumbnails/21.jpg)
The unfiltered water from both the
spring and swamp was unsafe especially for drinking as it contained coliforms and large particles.
After filtration and chlorination, both spring and swamp water was clear and did not contain coliforms.
Discussion
![Page 22: Nabisunsa Girls School, Kampala, Uganda. United we stand To carry up our flag To fight for our nations health Our hearts and minds we pour The water](https://reader038.vdocument.in/reader038/viewer/2022110116/5517b3a4550346892b8b4599/html5/thumbnails/22.jpg)
We conclude that this method was
effective in cleaning swamp and spring water and could be used for water treatment for domestic use.
